I don't know if this is the correct forum to place this question but I've been jamming to some Pink Floyd lately and have found a couple patches on some Ipad synthesizer apps that fit well with 'Sorrow' and 'Shine on you crazy diamond'. I'd like to manually advance to the next note/chord with a footswitch after programming the chord sequence. Crazy Diamond is a good example since there's really no fixed timing and sort of goes by feel. Dream Foot looks like the right app but I really don't know anything about midi. I do have a Thunderbolt to Usb (camera) and wondering what my next purchase/step is.
Thanks!
