Dan, this is great. Personally, I would really like to be able to use the accelerometer to adjust different parameters in a single iPad synth. On the iPad, it really only works when all the parameters are mapped as different CCs on a single MIDI channel. So the above solution won't work (as each parameter is on a different channel).
I am putting together a layout that has 4 layers of sub-controls and uses MIDI Designer Lite as a MIDI pass-thru just to be able to do what I want. Basically, it sends a channel changing CC out to six knobs in MDLite and back to MDPro on separate knobs on channels 1-6. Those knobs have subcontrols that are all on channel 1, which will go to my synth on channel 1.
Good news, it works! But I'm afraid it will end up clogging up the iPad's virtual MIDI and slow down or crash when I already have multiple audio and MIDI tasks running on the iPad.
So my request:
Is there a way to set a channel changing knob so that it sends its commands within MIDI Designer, to another knob? If so, I can't find it. If not, please add this option.
