This app is a sampler instrument and a midi controller with a powerful built in chord generator.
Easily compose chord progressions with rich and emotive extensions, transpose them into any key and customize the voicings to your exact preferences.
Either use the built-in sampler instruments to play on your device, or connect to your DAW for full midi input to your favourite synths.
Use the launch pads and midi CC dials to control scenes, drums or parameters in ableton or any other DAW.
Theres also a songbook with hundreds of famous songs which you can play with very little music theory background.
The whole app is based around simple scale numbers, which are the gold standard for understanding music.
