I made a quick video of using an iPod Touch and TouchOSC to control a Commodore 64 in real time.
Using the default 'Keys' patch for TouchOSC, a number of parameters of the Commodore 64s sound chip, the SID, can be controlled:
• Note on and off commands for two octaves' worth of piano keys
• Filter frequency
• Filter resonance
• Enable / disable triangle waveform
• Enable / disable sawtooth waveform
• Enable / disable pulse waveform
• Pulse wave duty cycle
Although this is only a preliminary mapping, I do like where this is going from a performance point of view, and I will be working on better / more meaningful mappings in the near future.
