Correct. I was responding to the question earlier in the thread where folks wanted to know if they could change FTP patches from another source. To my knowledge there is no practical way to do so.
Back to the original question - like most MIDI challenges, it's more difficult than it ought to be... Different vendors support different functions, & they all have their quirks.
Since the FTP won't (practically) respond to PCs, you either (a) change all patches thru the Dpad, or (b) you don't... And if you're not using the dpad, why bother with the FTP app at all.
I've tried many configurations, & the two best FTP rigs I've used were:
- Hollyhock, a programmable DAW/VST host, which I used to pre-load soft-synths (perfect flexibility)
- FTP driving my GR-30 (simple & easy & great sounds, but limitations on programmability)
With Hollyhock, I used the dpad to change patches. But I basically used all FTP "hardware synths", within the FTP app; I did not use it as a VST host. This is because I wanted to preload voices in my VST to avoid patch change times (I used SampleTank Live Sets to preload all samples). So I wanted SampleTank to manage patch changes, not the FTP app. The FTP app just lurked in the background.
There are many ways to approach this. You just need to choose your favorite synths & synth behavior/functions first, then work back from there.
