    1. Has worked brilliantly on my ipad1 since day 1. Not a single problem.
      Try a powercycle by holding down the home and power button at the same time until you see the apple logo on screen. Then release and wait. Also make sure all background apps are closed.
      Awesome synth app!

  1. yeah it sounds pretty good and it’s really expressive. the demo almost convinces me to get the full version. but i still think it’s too expensive. at half the price i’d get it.
    one possible ui improvement would be a full screen keys area, same problem with animoog, the keys are too small.

    1. i don’t have a problem with the animoog keys, however i agree that these ppg keys are too small. And it looks like there is room to lengthen them.

    2. price is totally fair , it does really sound really goood + its super deep synth
      also hook up midi for proper keys , or use some free virtual midi app

  2. more on the keys,
    i’d like to see that panel to the right of the keys pop in and out via a button above it. as well as a way to enlarge the key size.
