On the other hand I can't see the need in ableton for a high-er resolution faders/pots (correct me, I know you will).

I am not sure about that, spectrasymbols prizes arent very keen for one off production, and the prizes I received were insane. It could be I have choosen some not standard parameters, but I did tell them to suggest any changes to reduce the cost. Also,according to the uk distributor, the xy pads arent very reliable, I have one from them, still waiting to be tried..

I had a chat with a technician from elo, and he stated that the Carrol touch (led-photoreceptors) technology will be faster. I have tried 3technologies from them briefly, now trying to get them to lend me some touchscreens, so i can have a look a them a bit closer. It seems to me that it will be possible to get them respond "immediately", since intervals, the controller reports to the computer, are very customizable. Either from 0 to 3000ms in 10 ms steps, where 0 and 10ms setting can flaug the computer, or you can send the controller a message from the driver to respond with currently touched coordinates, or it can immediately respond when a change occurs. No affordable-responsive-working in daylight multitouch technology is available at present. I am sorry for this slight offtopic. I too wanted, to go with a polytouchable controller, but I decided to give priority to visual feedback. I am still considering Led rings or RGB leds to go around this, in which case I would use samples from spectrasymbol

regarding elo monitors: utitlity to configure the controller: http://www.elotouch.com/files/utility/smartset.exe can be ran without any elo monitors to see what can be tweaked, or just read here: software driver user guide: http://www.elotouch.com/files/manuals/sw500861.zip

Should the computer be used for the calculations, then yes, all we need is to connect the lcd to the computer without the controller. however this will limit the controller to be used on Unix systems, I reckon. I am not sure how different operating systems and programs which will be controlled would react to multiple movements at once. I doubt that there wouldn't be problems. This is why I prefer to built a controller for it. I remember reading somewhere on this forum, that since the core v3, it is feasible to send data from midibox via 100MB LAN. This would be the ideal, OSC input over LAN to the computer. Each OSC message would have an ID representing a moving point on the screen: user touches the screen --send ID and coordinates of the point of touch user moves his finger on the screen --send ID and coordinates user untouches the screen --send ID and coordinates of this point of release I see speed of data transfer as the advantage of OSC over using MIDI. However, many computers for music are setup with LAN disabled, since doing so improves latency without clicks greatly. At least on Windows machines. Therefore, 14bit midi CC messages might be actually better. --------- I want to know whether this is at all possible, so I dont waste time trying to accomplish this. Obviously I would very much welcome anyone to join me for this project, since the kind of programming of the software for the controller is new to me.

Hi, I am not very technical, and I will really appreciate if you could tell me wether this project is doable. I have long been looking into multi touch screens and apart from that diy project, whereby using a projector and camera, one can analyze the video and get the "touched coordinates". project link: http://multi-touchscreen.com/#makemultitouch . the diy version of it is described here http://portal.acm.org/citation.cfm?id=1095054 . It has a few disadvantages, namely high cpu requirements, time resolution typically of the 30fps, and facing the possibility of errors when operating in daytime. I have tried a few elo monitors, they are very well built and are using many diffferent technologies. Here are the ones I consider as candidates for this project, the technologies have moved: --- Acoustic pulse recognition: http://www.elotouch.com/Technologies/AcousticPulseRecognition/default.asp) ............supports sensing of XY axis and is stable under many conditions, even poor grounding etc. It amplifies sound generated when you touch the monitor and then comparing the waveform to a stored table of waveforms. Adjacently pressed coordinates are averaged by the controller and then sent to the computer using the driver. Intellitouch: http://www.elotouch.com/Technologies/IntelliTouch/default.asp ...................is more prone to defects, however it allows for sensing of three axis. The way sensing is done is by comparing the, pressure modulated, high frequency sound passing through the touch areas to stored table of waveforms. Again concident coordinates are averaged and passed onthe driver Carroltouch: http://www.elotouch.com/Technologies/CarrollTouch/default.asp .....two axis sensing, using a matrix of led-photoreceptor pairs --- Eah of these connect to a controller via either 5pin din analogue connection, or 8pin din digital connecton Info on the software and hardware: http://media.elotouch.com/pdfs/manuals/program.pdf My question is, is it possible to make a controller for this touch technology that will generate a table of touched points on either xy or xyz, then creates groupes of touched points and transmits each of these groupes as a touches, drages to a unix system, which will be able to interpret this as separate touches/drags to applications, which would respond accordingly, ie polytouch. All this, ideally at a rate of 1ms. MANY THANKS!!!

Thanks for the reply. It is not enough for me to have only the clcd. i will have some ribbon controllers (anyone managed to get these in europe? they seem to be only for wholesale. siemens use them in fact.: http://www.spectrasymbol.com/linearposition.html ) and external sensors and would like the display to show some data when i press them, etc. i am not a programmer, however i guess there is code to inspire from , or at least it seems that the commands are universal. having ruled out the clcd, here is another link for the ATM12864D glcd with KS0108 chip.: http://www.hebeiltd.com.cn/lcm.datasheet/ATM12864D.pdf from the pdf: PARAMETER SYMBOL RATING UNIT NOTE Operating voltage VDD -0.3 ~ +7.0 V *1 Supply voltage VEE VDD-19.0 ~ VDD+0.3 V *4 VB -0.3 ~ VDD+0.3 V *1,2 Driver supply voltage VLCD VEE-0.3 ~ VDD+0.3 V *3,4 so its negative suply voltage. however, all pdfs for this diplay are somehow corrupted. is there any other info (for programming) i will need apart from the coonections to the ks0108, which i can obtain from somewhere else?

Hi, and a big thank you for all that made this project happen!!! I am building an MB64E. 1.. What advantages will an GLCD bring? Do I understand correctly that an LCD will only support letters/numbers to be displayed? 2...my choices are: LCD: HD44780 based 16x4characters MC1604B-SYL ( info: http://www.everbouquet.com.tw/MC1604B.htm ) @10euros GLCD: KS0108 based 128x64pixels MG12864-SYL/H (info: http://www.gme.cz/linkydok/68a8fd68ac9a154d3361404c03354384.pdf ) @20euros Will I be needing MAX759 DC converter for anyone of these? javascript:void(0); Grin Thanks, Petr Ocka
