Abandonware - no updates or fixes in years
App is still broken: you have to turn on location services for it to even start, but then it can only play sound via the 1/8" stereo headphone output.
Unfortunately the app seems to be abandonware at this point in time - Akai hasnt updated it in years in spite of the annoying problems and 1-star reviews.
It needs to be fixed to start up without crashing, to play audio through the iPad speaker, and to support AudioBus/ACP/inter-app Audio and iOS 7.
The synth engine also needs work - it exhibits annoying aliasing at high pitches.
