Yes, pduino makes OSC redundant, and a range of values from 0 to 1023 should be enough for most effects, but anyway, in case a wider range is needed, I think the following can be a quite simple solution : <a rel="nofollow" target="_blank" href="http://interface.khm.de/index.php/lab/experiments/connect-a-ltc2400-high-precision-24-bit-analog-to-digital-converter/">http://interface.khm.de/index.php/lab/experiments/connect-a-ltc2400-high-precision-24-bit-analog-to-digital-converter/</a><br>
This converts the analogic signal to a 24-bit value!

I second that, arduino will do! <div>But if you want to built an "pd-independent" device, you can use OSC in arduino - although much harder than simply reading values with pduino - some guys already posted code for sending OSC messages from arduino devices [1], so then you can plug it to whatever you want: pd, ardour, osc-to-midi apps, processing, supercollider :D</div>

There are two problems arising when attempting to built a USB pedal : first you need to actually make the pedal (the traditional cry baby
design is probably the easiest way to go), then you need to connect it to a good usb gamepad. I insist on the "good" here because it is essential if you want to have a decent expression pedal. The best would be to test the gamepad before buying it and turning it into a pedal.<br>

Do you have any examples (photographs, audio samples) of the device you made? I am curious!<br>Achim<br><br>--- En date de : <b>Dim 6.6.10, Pierre Massat <i><<a rel="nofollow" target="_blank" href="http://mc/compose?to=pimassat@gmail.com">pimassat@gmail.com</a>></i></b> a écrit :<br>
