Ah great point I have not tried the iPad app, I was however thinking of something more along the lines of a push or Roli rise, machine something with pads maybe something that could do midi to cv conversion, make it easier to tie in non midi external gear. I have not had a chance to try the new pressure sensitive iPhone but if they adapt that to the iPad ...... Could be quite interesting! Thanks for reminding me of the iPad app I will try it!
