What we need now is a generic Karma. Make your own voice tables from whatever synths and arrangers you have, put in the CC codes for whatever it is doing to the voice (filter parameters, envelope parameters, LFO's etc) and the effects (types, depths, modulations, tempo syncs, etc.) and then run it from Nano or Controller keyboard knobs and sliders.
Then we can run this into whatever we want to. Heck, if it's already Mac, it can't be hard to port to iPad. Touch screen for sliders, switches, you name it.
I am surprised that Kay hasn't already tried to do something like this for all the arranger players out there. If there is anyone that gets this, it's us!
