Use a voice key connected to the game port of a sound card or wait till I build a digital voice key (but that will be weeks). You will have to use the keyword (something like with an in the parameter line) and I recommend getting a joystick and gutting it to interface the VOX to the gameport replacing one of the joystick switches with the VOX's relay. As for a voice key LaFayette make a reasonable unit with relay outputs. -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ Next time, give "the gift that keeps on giving": a female kitten.

Specifically, how the issue of sensitivity should be dealt with. The way the digital VOX is going to work is that with the CLOCKON frame being displayed DMDX will starting recording into a fixed length input buffer (length determined by the subject RT timeout) and then every 100ms or so (user specifyable) it will examine as much of that buffer that has not been examined already and that is examinable and look for a sample that exceeds the threshold for vocalization and when found calculate when that sample was recorded and generate a subject RT accordingly. It is the determination of that threshold that is the intriuging thing. On a conventional electronic VOX you've usually got a dial and meter and you set the microphone apparatus up and pretend to be a subject adjusting that threshold dial till you are sure it can't be adjusted any better -- you're certainly almost never happy with it, but that's a VOX for you. DMDX is not likely to be any different (except that you can get it to record the vocalization as well and perhaps perform some post run refinement of RTs), however the issue is how and where is that threshold to be set and for how long should it be remembered? Options include: (1) Only allowing it to be set in TimeDX, providing a VU display feedback and so forth and the resulting threshold stored in the registry and all runs of DMDX simply use that value. (1a) Same as (1) but having another button in the DMDX main dialog to determine the threshold and not using TimeDX at all. (2) Allowing DMDX to enter a special mode similar to a testmode (ie, as part of an item file) to determine the thresold providing a VU display &c., storing the resulting threshold it in the registry (using that value for the initial setting of course). (3) Allowing the experimenter hit a key as DMDX is running that stops the job till the threshold is adjusted. (4) A simple item file parameter and forget the registry and all that fancy crap. I don't like option 3 at all, however it provides the functionality that most closely mimics and electronic VOX. I don't expect anyone will want option 4. I prefer option 1a over option 2 because it's likely that once the threshold is set it won't need to be adjusted for individual subjects (Ken for instance asks the subject to speak louder instead of adjusting VOX sensitivity) and I prefer 1a over 1 so that in the event of constant casual adjustment of the threshold being necessary users not necessarily familiar with TimeDX won't have to run it and run the risk of inadvertantly borking the whole display system. -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ The brain works from the moment of birth until you stand up to speak in public.

Especially because it gives so much flexibility in measuring naming response times copmared to an electronic voice key. As far as configuration issues go, I think it's probably best to keep novice users away from TimeDX if possible, and to not use TimeDX to set thresholds on a subject by subject basis. Out of your suggestions then: > Options include: > (1) Only allowing it to be set in TimeDX, providing a VU display feedback >and so forth and the resulting threshold stored in the registry and all >runs of DMDX simply use that value. > (1a) Same as (1) but having another button in the DMDX main dialog to >determine the threshold and not using TimeDX at all. > (2) Allowing DMDX to enter a special mode similar to a testmode (ie, as >part of an item file) to determine the thresold providing a VU display &c., >storing the resulting threshold it in the registry (using that value for >the initial setting of course). > (3) Allowing the experimenter hit a key as DMDX is running that stops the >job till the threshold is adjusted. > (4) A simple item file parameter and forget the registry and all that >fancy crap. I think setting an overall level and threshold in TimeDX is the right way to go - ie. option 1. I think adding an item file parameter (option 4) is not very useful. The setup is likely to be machine specific and hence best configured and stored in the registry. However, like frame duration, I think digital vox settings should be written to the .azk file when used. It should also be possible to adjust thresholds on a subject by subject basis without going into TimeDX - I guess this would require something like option 1a or option 2 in addition to option 1. Maybe you should have a button in the test mode that will make changes permanent by writing to the registry, but not do this by default. That way it will be easy to make changes for a particular subject and return to the default values subsequently. As for option 3, I think a big advantage of Digital VOX is that if the voice key stops working correctly then you can still rescue the results, simply by running an analysis after the end of the experiment on the sound files that have been recorded to the computers hard drive. Maybe this makes changing the threshold during the experiment less important - though I guess having this available would be useful. There is a piece of software called RunWord, developed by Chris Kello that takes this approach - storing sound files and analysing them later. Runword includes a iece of software called RunVoice that does a two stage (forward then backwards) parse of the acoustic signal allowing very sophisticated acoustic measures to be taken from speech files. It may be that looking at the way that Runword is set up may be useful to you (or maybe allowing DMDX to use runvoice for acoustic analysis). You can find more info on it here: http://www.cnbc.cmu.edu/~kello/runword.html there is also a paper on the software that describes the acoustic analysis in more detail. Kello, C. T., & Kawamoto, A.

You mentioned at some point maybe dooing some modelling of morphology. I am all fired up after Aix (it won't last....) and have a couple of ideas. Contestant number one....Modelling the affix priming results. We have no/marginal priming for non/less productive affixes, priming for productive affixes and no priming for inflectional affixes. The idea for the derivational is that the productive affixes are in some way separate items where the non prod are locally attached. I suppose they would be more clustered in lexical space with fewer outliers due to the freedom of use and lower restrictions on what they bind with. The inflections are more so, but differ in that they are vastly more frequent and consistent, have different functions etc. Assuming we can get away without doing it all in context, can we model the priming results with simple frequency, consistency of meaning etc? Quantitative change causing qualitative differences. Do three affixes, non prod, prod, inflectional. Contestant number 2.....Delayed priming? Why we get morph and not sem? Simply speaking a form and meaning morphological relationship, the kind that exists with massive frequency in the language as a whole is a much stronger relationship than one of overlapping semantics (e.g. cello-violin) or form (electrode-elect) which are single examples? Can delayed priming be modelled? The above result is often taken as proof of a separate effect of morphology. - Mike xoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxox Mike Ford MRC Cognition & Brain Sciences Unit [Ex Applied Psychology Unit] Tel: 01223 355294 ext 241 15 Chaucer Road Fax: 01223 359062 Cambridge CB2 2EF email: mike.ford@mrc-cbu.cam.ac.uk http://www.mrc-cbu.cam.ac.uk/personal/mike.ford xoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxoxox From DMDX-owner@psy1.psych.arizona.edu Wed Jun 9 07:49:38 1999 Received: from sirius.mrc-cbu.cam.ac.uk (0@sirius.mrc-cbu.cam.ac.uk [192.153.213.178]) by psy1.psych.arizona.edu (8.8.7/8.8.8) with ESMTP id HAA11919 for ; Wed, 9 Jun 1999 07:49:34 -0700 Received: from pc66 by sirius.mrc-cbu.cam.ac.uk with Sendmail (8.8.8/V3080601); Wed, 9 Jun 1999 15:49:31 +0100 (BST) Message-Id: <3.0.5.32.19990609154931.008a74c0@pophost.mrc-cbu.cam.ac.uk> Date: Wed, 09 Jun 1999 15:49:31 +0100 To: DMDX@psy1.psych.arizona.edu From: Mike Ford Subject: [DMDX] Ooops Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Reply-To: DMDX@psy1.psych.arizona.edu Sender: DMDX-owner@psy1.psych.arizona.edu Precedence: list Sorry for the accidental mailing.

Hence it's not exactly the most tested of DMDX switches out there and has had a rather glaring hole in it's logic for a long time in that a frame with only an E switch in it produced no display queue element when it should have resulting in out of sync back buffers (which results in displays containing previous frames or parts of them). This has been fixed in 1.1.02 which has not been released yet because we are hunting for another more worrisome display error (that has the same kind of dramatic symptoms) and 1.1.02 will address that issue as well. Basically if you have scripts with the E switch in them they should be removed in any event as even when E is functioning correctly it has dramatic performance degrading issues (the DMDX help file has details). -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ Where in the world does the guy who has everything put it?

So use it in conjunction with RecordVocal for now.

n148 s64 f12 <nfb> <os 5,0,2,5>

(d) and a subject is nice for the archive, like "stray pixels". What you should do is to remove scrambling from your item file and see if the stray pixels turn up after the same item or whether it is in fact some kind of random affair. If it is random then you should observe your presentation sequence very closely and see if the order of frames has been corrupted, if so then you are facing the same error I am trying to solve in Ken's lab right now. If it always occurs at a given point then you should decide to which side the stray pixels are occuring, the left, top, right or bottom and then you should increase the appropriate number in the keyword by some small amount, for example if you notice that the pixels are being left at the left edge of the frame then an is ok, if at the top an might be required, if at the right .

The machines that exhibit this behaviour are all P166 machines and I sure as hell can't replicate it on any other box I've got, they're all faster. 'Course it's complicated by the fact that only certain people can produce the error with any reliability and even then it can take them many minutes before the error occurs but I've seen it with my eyes so I know it's there. -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ Chicago Transit Authority Rider's Rule #36: Never ever ask the tough looking gentleman wearing El Rukn headgear where he got his "pyramid powered pizza warmer". - Chicago Reader 3/27/81 From DMDX-owner@psy1.psych.arizona.edu Mon Jun 28 16:13:27 1999 Received: from jcf (jcf.Psych.Arizona.EDU [128.196.98.7]) by psy1.psych.arizona.edu (8.8.7/8.8.8) with SMTP id QAA30967 for ; Mon, 28 Jun 1999 16:13:03 -0700 Message-Id: <3.0.1.32.19990628162101.006898e8@psy1.psych.arizona.edu> Date: Mon, 28 Jun 1999 16:21:01 -0700 To: DMDX@psy1.psych.arizona.edu From: "Jonathan C.

I have released 1.1.04 that includes the following: The DigitalVOX input device no longer stops the capture buffer immediatly after a response is detected. You can use it by itself (no need to include the RecordVocal device as well) now but it will always leave the capture buffer running for the response time limit (like RecordVocal) meaning DMDX won't go on the the next item or respond to a request until the response time limit is reached. It'll stay that way until I dramatically re-design the code, you may want to pick a smaller response time limit if the ISI starts being a problem. Fixed missing quotes making scramble report a missing $. DMDX always clears the backbuffers on abort/save dialog. Stops multimon screens leaving something from n frames ago on the screen when job is stopped. S3 ViRGE PCI 325 (not the DX/GX) video card feedback clearing problem kludged. The machines in Ken's lab could somehow not display the frame that cleared the feedback message, instead whatever was in the video memory buffer from n frames ago (like 13 frames ago on a 4M video card) would be left on the screen. I have made the generation of both those messages (the feedback and it's erasure) grab the critical section that stops the display queue from being manipulated and this seems to fix the problem. My guess is that the flip of the first frame was somehow cancelling the blit of the erasure, like I say somehow because there are much more rigorous tests that those machines pass (like twenty 1 tick frames right after each other where at least 7 frames are being blitted while other frames are being flipped). Once again, the error was only seen with those S3 chips, the S3 DX/GX version I have doesn't display the error, but it's also in a 300MHz K6 machine, it could still be CPU speed dependant. -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ "... all the modern inconveniences ..." - Mark Twain From DMDX-owner@psy1.psych.arizona.edu Fri Jul 2 16:30:57 1999 Received: from jcf (jcf.Psych.Arizona.EDU [128.196.98.7]) by psy1.psych.arizona.edu (8.8.7/8.8.8) with SMTP id QAA09120 for ; Fri, 2 Jul 1999 16:30:46 -0700 Message-Id: <3.0.1.32.19990702163928.00689570@psy1.psych.arizona.edu> Date: Fri, 02 Jul 1999 16:39:28 -0700 To: DMDX@psy1.psych.arizona.edu From: "Jonathan C.

And try as you might you can't find anything else that might have exclusive access to the sound card. The problem occurs because previous versions of the Sound Driver selection dialog in TimeDX incorrectly indicated what the currently selected device was, they always left the selection as the last device, not good as the last device is rarely the desired one and if someone presses OK, voila, no more sound.

Previously DMDX only slept at the start of an item. 3/ Stopped movingimages() from moving stuff (with Blt, the BLock Transfer function) if a Flip has not completed as the blt will be queued and then go to the wrong buffer. This fixes the S3 problem in Ken's lab which wasn't related to the video card at all but instead the P166 processor was at fault. Basically if the CPU is slow enough the erase of a feedback message can wind up not being moved into video memory before the Flip of the feedback itself and the erase winds up in the wrong place leading to all hell breaking loose with the display. Once again, this only cropped up with feedback and on slow machines, if you didn't see it it wasn't happening as the results were fairly catestrophic. 4/ I made the About box a bit fancier, centered all dialogs, disabled screen savers and monitor power off programs. 1.1.07 will include a new input device that will poll joystick buttons as fast as pio12 buttons (read as fast as possible), the catch being the joystick must be an old fashioned analog thing on port 201H. It won't work on NT or win2000 (like the pio12 input device won't) nor will new fangled joysticks work with it, you'll still have to use the DirectX devices for those. -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ Any philosophy that can be put in a nutshell belongs there. - Sydney J.

My development systems are all celerons and the test machine is an AMD K6 so it works well on those processors. I don't recommend wasting money on P2s or P3s, it's almost impossible to measure the performance benefit with DMDX. If fact the AMD processors are likely to be faster clock for clock than the Intel devices. The element that makes the largest difference to DMDX is the video card and even here you have to want refresh rates in the order of >150Hz before you can justify the latest video cards (and you'd have to buy a wickedly expensive monitor for even >85Hz). Basically a TNT based video card with 16megs of ram for around $100US represents the top of the usually used hardware requirements (especially if you plan on using full color photographic stuff), otherwise a Riva128 based card with 4megs of video ram for around $50US will suffice. If you want tic durations lower than 11.5ms and are prepared to pay for a monitor to display them then a TNT2 or Matrox G400 could possibly be justified but even then the TNT specs have 200Hz in there. -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ He is truly wise who gains wisdom from another's mishap.

So that would indicate that there is trouble with your DirectSoundCapture device. I take it that you can record successfully using the plain windows routines that non-DirectX programs use? Unfortunately the diag/info programs (under Program Files / DirectX / Setup there is a program called something Like DxInfo under DX5, it's DXDiag in DX6) that I see make no reference to DirectSoundCapture devices so I don't see any way to get diagnostics there. Perhaps you could try installing DX6.1 (dx61eng.exe) and see if that rectifies things. There's not really a lot more I can do, all the code that interfaces with DirectSoundCapture checks error codes religiously and works on three different machines of mine with two different sounds cards (and SB16 PnP and a TBS Montego), one quiet old and one quiet new one. Perhaps you have run into the problem of a sound card not being able to do full duplex, that is the ability record and playback at the same time, a necessity for DMDX -- you might want to check the resources allocated to the sound card in the machine's Device Manager and see if things look ok. I was going to suggest that the sound device should have two DMA channels but I notice that the Turtle Beach Montego I have only has a single interrupt and no DMA channels at all for it's PCI audio device, the sound blaster emulation has one interrupt and two DMA channels, however I really doubt that DMDX would be using the sound blaster emulation. Perhaps your sound cards just can't do full duplex audio. -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ You can't have everything... where would you put it? - Steven Wright From DMDX-owner@psy1.psych.arizona.edu Wed Jul 14 21:20:19 1999 Received: from homebox (tec3.psych.arizona.edu [128.196.98.11]) by psy1.psych.arizona.edu (8.8.7/8.8.8) with SMTP id VAA09540 for ; Wed, 14 Jul 1999 21:20:15 -0700 Message-Id: <3.0.1.32.19990714212423.0068d6c0@psy1.psych.arizona.edu> Date: Wed, 14 Jul 1999 21:24:23 -0700 To: DMDX@psy1.psych.arizona.edu From: "j.c.f."

All the measurements were obtained with the same program running on a single Pentium 300 computer. In all, samples of 1,000 timing measurements were obtained in each of 96 different conditions. Standard deviations of the times ranged from about 0.0006 msec under DOS 6.22 to almost 40 msec under Windows 3.11, representing an increase in timing error of up to 6,000,000% Researchers requiring millisecond timing accuracy are recommended to use DOS only. xoxxooxxxoooxxxxooooxxxxxoooooxxxxxxoooooxxxxxooooxxxxoooxxxooxxox Mike Ford MRC Cognition & Brain Sciences Unit [Ex Applied Psychology Unit] Tel: 01223 355294 ext 241 15 Chaucer Road Fax: 01223 359062 Cambridge CB2 2EF email: mike.ford@mrc-cbu.cam.ac.uk http://www.mrc-cbu.cam.ac.uk/personal/mike.ford xoxxooxxxoooxxxxooooxxxxxoooooxxxxxxoooooxxxxxooooxxxxoooxxxooxxox From DMDX-owner@psy1.psych.arizona.edu Thu Aug 12 09:53:28 1999 Received: from homebox (tec3.psych.arizona.edu [128.196.98.11]) by psy1.psych.arizona.edu (8.8.7/8.8.8) with SMTP id JAA02242 for ; Thu, 12 Aug 1999 09:53:23 -0700 Message-Id: <3.0.1.32.19990812095745.006998c4@psy1.psych.arizona.edu> Date: Thu, 12 Aug 1999 09:57:45 -0700 To: DMDX@psy1.psych.arizona.edu From: "j.c.f."

You can check out the testmodes in DMDX, one of them displays the latencies in the millsecond callback, it is these latencies that are used to poll PIO12 and joystick switches, typical values on my machines are 0..2ms with the odd 3..5ms value representing about 0.00001% of the values. In the Input section of the DMDX help file are a number of timings of keyboards, variations are 2..3ms on a good device and worse with shoddy devices. Personally I don't see how you can get 0.0006ms deviation with a keyboard _ever_, the device has an embedded processor in it that scans the keyboard 5 keys at a time and when it finds a key it sends it to the PC, I can't imagine any keyboard is polled at 1/0.0000006Hz, 1/0.006Hz maybe... -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ Managers know it must be good because the programmers hate it so much.

Relative accuracy of DOS vs Windows. Myors uses a very simple test. He just presses a key and keeps it down. This sends a continuous stream of keypresses to the O/S at regular (definable) intervals. He then measures the intervals between characters. Under these circumstances, there is no polling of the keyboard (unlike the situation in an actual experiment), so this method excludes that source of variability. So, the ONLY source of error is when the O/S intervenes for some purpose. With DOS, it never intervenes, so timing is perfect. But with Windows, intervention is quite frequent, since it is a multitasking operating system. The point is that this test exaggerates the difference between DOS and Windows. Under actual experimental conditions, with a subject pressing the key in response to a display, the difference may be much less. Figures for DM/DMTG suggest that keyboard errors (using the SHIFT keys) range from 13 to 23 ms (see DMASTR Release Note 13), and they do not appear to differ markedly from those available for DMDX, which range from 40-47ms on an old AT Keyboard, 33-40ms on an OmniKey 102, and 33-69ms on a cheap Win95 KB. The "Input" section of the DMDX Help file contains an extensive discussion of these issues. 2. Inevitability of timing errors in Windows Myors says that "it is likely that the problems illustrated here are due to the multitasking kernel per se and will be evident [even] in programs written specifically for Windows." This is quite wrong. Jonathan specifically set out to write a program that took the multitasking characteristics of Windows into account. He uses the High Performance Timer, which comes on the motherboard of Pentiums, which is a very accurate, uninterruptable clock. If DMDX has been told that the refresh cycle on this machine (at this screen resolution, with this monitor, and this graphics card) is 13.75 ms (this is what TimeDX does), and it notes that 14.3256 ms has elapsed since the last refresh, then it infers that it must have missed it, due to the fact that DMDX wasn't running when the refresh signal actually occurred. So it adjusts its count accordingly. So, no error here. When the time comes for a new frame to be displayed, DMDX sets a switch such that the "flip" to the new page will occur at the time of the next retrace. Therefore, so long as DMDX gets control at any stage during the penultimate refresh cycle, there will be no error. However, an error will occur if DMDX is pre-empted by the Windows kernel for more than an entire refresh cycle. This does happen occasionally (depends on the speed of the CPU and whether you have any other tasks running on your machine), and when it does, an error message is displayed on the .azk output for that item, and on the file "diagnostics.txt". TimeDX also has tests that tell you how often this happens. As for timing RTs correctly, there are various sources of error. One is the time taken for the microprocessor in the keyboard to poll the keys. This varies from one keyboard to the next, and from one brand of keyboard to the next. As noted earlier, Myors' method excludes this error altogether. Another source of error is whether DMDX is running at the precise moment when a response button is pressed. DMDX is set up so that it asks the kernel for a "call back" every millisecond. Most of the time, this works, but occasionally, the kernel fails, and you might have two or three ms elapsing between call-backs. In this case, the RT will be overestimated by two or three ms. (This does not apply to keyboard responses). How often does this happen? Again, it will vary depending on your CPU and the other things that are running. To enable users to find out how often this occurs during their experiment, Jonathan has written two Test Modes into DMDX that can be called from the .rtf file. These indicate on the screen how many call-back errors occur, and their duration. Errors as great as three or four ms occur with a very low probability on the test beds we have used. 3. Conclusion The timing errors involved in DMDX are nowhere near the magnitude suggested by Myors (1999), and users should not be alarmed. However, we urge all users to conduct thorough tests on their own machines using the various diagnostic tests that have been provided. --Ken Forster From DMDX-owner@psy1.psych.arizona.edu Fri Aug 13 16:41:04 1999 Received: from trifid.u.arizona.edu (root@trifid.U.Arizona.EDU [128.196.137.197]) by psy1.psych.arizona.edu (8.8.7/8.8.8) with ESMTP id QAA05869 for ; Fri, 13 Aug 1999 16:40:57 -0700 Received: from cg6.psych.arizona.edu (cg6.psych.arizona.edu [128.196.98.27]) by trifid.u.arizona.edu (8.8.8/8.8.8) with SMTP id QAA08990 for ; Fri, 13 Aug 1999 16:40:57 -0700 Message-Id: <3.0.6.32.19990813164106.0089fab0@pop.u.arizona.edu> Date: Fri, 13 Aug 1999 16:41:06 -0700 To: DMDX@psy1.psych.arizona.edu From: Kenneth Forster Subject: [DMDX] Re: Revamped Web Page Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Reply-To: DMDX@psy1.psych.arizona.edu Sender: DMDX-owner@psy1.psych.arizona.edu Precedence: list From: Kenneth Forster Date: August 13, 1999 Topic: New DMASTR Web page I am starting the process of updating the DMASTR Web page.

And in light of whatever article that was recently that said DMDX couldn't do what it does I'm going to add four new modes that monitor the latency of the keycheck() routine that recieves keystrokes and decides whether they are a valid response or not. Normally this wouldn't tell us anything, however if you say held down a key so the keyboard starts the autorepeat function then you could see what variablilty (if any) is present in keyboard based RTs (as opposed to PIO and RawJoystick based RTs that vary with to the millisecond callback) due to win32 as opposed to the inherant variablility of a keyboard. -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ Old frogs never die...but they do croak.

This is usually associated with '9x not correctly knowing what monitor is attached to the machine, consequently when it reboots it goes into auto detection mode and tells the driver that there's a different monitor out there and the the driver only provides settings that the monitor can handle -- so being provided with the option ot tweak refresh rates is dependant on the monitor you have (or that '9x thinks you have) plugged into the machine. -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ Bureaucrat, n.: A person who cuts red tape sideways. - J.

With DMTG's insane screen clearing philosophy this was possible, with DMDX's default behavior of a frame implicitly clearing anything else remaining on the screen unless a no erase has been set this is not possible, you couldn't specify a no erase for the feedback, allows this.

I am trying to write an item file that will play three videos simultaneously, but can't get it to work. The item +1 “ball&tree”, “path” , “manner” / ; gives a "missing clock-on switch" despite the help file saying that: "When turning the clock on for responses at a given digital video frame with the switch the normal DMDX clock on switch should not be used as well" BUT, adding the normal DMDX clock-on switch ( * ) like below +1 * “ball&tree”, “path” , “manner” / ; results in an item that only plays the last video entered in the item. I've rearranged these several times, and it will only play the last video in the item. Is this a bug, or am I writing it all wrong? thanks for any help Matthew Finkbeiner From DMDX-owner@psy1.psych.arizona.edu Thu Sep 2 12:55:47 1999 Received: from jcf (jcf.Psych.arizona.edu [128.196.98.7]) by psy1.psych.arizona.edu (8.8.7/8.8.8) with SMTP id MAA26520 for ; Thu, 2 Sep 1999 12:55:43 -0700 Message-Id: <3.0.6.32.19990902130106.0079bb20@psy1.psych.arizona.edu> Date: Thu, 02 Sep 1999 13:01:06 -0700 To: DMDX@psy1.psych.arizona.edu From: "Jonathan C.

If you have an up to date version then something new is busted. Your other problems probably stem from using the comma operator with digital video (I don't think I've ever tested it), in that the attempt to start three streams simultaneously fails, try them with a short interval (1 tick should suffice) between them and no comma. I never really intended that this feature be used, it just happened to be a natural ability arising from the way I built the code. -jonathan (j.c.f.) /"\ \ / X ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL / \ "It's bad luck to be superstitious." - Andrew W.
