A Guy Called Tom (yes, that’s his name on Vimeo) is using the TouchOSC app on his iPhone to control a modular synthesizer. Pure Data is doing the heavy lifting, converting the data to MIDI. Here is what he says about it:
TouchOsc iPhone app sending osc data into PureData Extended, where it is converted to midi and sent to the Doepfer MCV24 which converts it to voltage and controls the modular synth.
TouchOsc XY Pad controls the pitch of two Thomas Henry VCO-1 which also crossmodulate each other.
TouchOsc Sliders control Elby Steiner filter cutoff, Plan B Model 10 env cycle speed, Doepfer BBD feedback and delay. Thomas White LPG used in both mode for amplification. Delay is a Stereo Memory Man with Hazarai. Sorry for the video quality, its done using a photo cam.
Using TouchOsc is fun, there is a lot of control right at your fingertips. Actually it can control way more than i have to control :) Really cool app. Disadvantage is the steping in the control voltages that you can hear quite well, especially when controlling the pitch of oscillators. Not sure if its the midi resolution, the mcv24 or the application itself.
This is very cool. I was experimenting with TouchOSC during my Special Projects in Music Technology class last quarter. I was just using my iPod to control some sounds in Pure Data, this is taking it to the next level. Maybe even the level after that.
