We have just released an update of modstep that features AUv3 improvements, several bugfixes here and there and finally complete Audiobus 3 support including MIDI and audio.
Bugfixes
- fixed several smaller layout issues
- fixed an issue that could cause Pitchbend and Modwheel assignments to be converted into unusable MIDI CCs
Note: modstep does not work with iPads prior iOS 8 anymore!
