iPad controlling two synths (TouchOSC, Evolver & Nova)
Background information:
For this experiment with my iPad I designed a basic layout for TouchOSC to help me control 2 synths at same time. To do that, I create a keyboard and 2 XYpads on the layout. The keyboard points to channel 1 (the novation nova) while the touchpads goes to channel 2 (DSI Evolver).
Using a Camera Connector I can drive coreMIDI to a midi interface with USB. The one I’m using here is an ESI Miditerminal M4U, that gives me 4×4 midi ports and 1 USB port. By doing this, the Miditerminal get both midi signals and power thru the USB from the iPad, and let me send midi signals thru different ports. The last step is to configure on each synth which midi channel will they receive, so there I had to set channel 1 on the Nova and 2 on the Evolver.
