Entonal Studio finally made it onto iOS!
Here it is running in the amazing AUM modular hosting environment:
The main app is the standalone version, and the bundled AUv3 plugin is the pure MIDI processor.
It's on sale for an intro price of $9.99 until the end of October, after which it will go up to $19.99. There's already a lot of buzz over at the Audiobus forum!
