midiFILTr-VF is an Audio Unit v3 MIDI Effect and CoreMIDI capable app that improves the MIDI capabilities of a hardware Volca FM synthesizer. The Volca FM is notorious for having a unique MIDI spec that does not listen to the velocity of incoming MIDI notes. midiFILTr-VF allows you to play notes with velocity as you would expect to by adding a MIDI CC message along with each note that controls the note's velocity. The Audio Unit also allows you to control the MIDI CC parameters of the Volca FM using AU parameters.
This app requires:
A hardware Volca FM synthesizer
A hardware MIDI interface connected to the Volca FM
An Audio Unit host that supports AUv3 MIDI Effects such as AudioBus or AUM is recommended for ease of use, though the app can also be configured with regular CoreMIDI.
Added AUv3 MIDI Effect
Includes support for MIDI CC control of the Volca FM using AU parameters
Future updates to this app will focus on Apple's Audio Unit v3 MIDI Effect format rather than the AudioBus effect format. AUv3s are very well supported by AudioBus so using future versions of the app shouldn't be a problem, but you should probably start choosing to use the AUv3 version in your AB projects for future compatibility
Updated to latest Audiobus
