MIDI transpose for single midi channel
I want to use a multi-timbal organ App that has 3 midi channels for upper, lower, bass. Midi channels 1,2,3. I want to transpose +1 octave, just midi channel 2 ( lower manual ) leaving channels 1,3 unaltered. I have midiflow’s Transposer but it appears that it transposes all incoming midi channels. So far the only way I can raise just the lower manual of the organ is by running two instances of the organ App, where one instance notes on midi channel 2 are raised by an octave and where I mute channel 1,3. The other instance of the App has channel 2 muted. It works but is less than ideal.
Would it be possible to use Midiflow’s router to route channel 2 through the Transposer leaving channels 1 & 3 unchanged? If not does anyone know how to transpose the notes of a single midi channel on IOS leaving all the other channels unchanged.
Thanks IA, Thomas
