Multitouch livecoding

I thought it would be interesting to explore multitouch interfaces for livecoding music. Here are some ideas:

• On a cellphone, you can expand your working area by using the phone accelerometers (and gyros, if available) to rotate the phone to move around a larger virtual space.
• Quasimodal interface elements pop up during a touch and then permit continuous adjustment in one or more dimensions with one or more touches — the same or different touches.
• Waveform and spectrum displays at different scales can elucidate what is happening in a single node.
• Individually reified signal inputs might offer a quasimodal action to overwrite them with some existing signal.
