Use the solo button of the Piano group if you want to hear this instrument solo.

Please contact me if you know of a better way to do the routing.)

(Note: I don't know whether it is possible to reduce this setup to two tracks.

Create a group that contains the 'MelodicFlow' and the 'Instrument' track.

Now all the notes that are generated by MelodicFlow will come through to the instrument. Set the Midi From box to the 'MelodicFlow' track, and set the second box to 'MelodicFlow'.

'Instrument' track: This track contains the instrument and the effects.This setup will combine the notes of the chord track and of the melody track to one note stream. Set the Midi From box to the 'Chords' track. 'MelodicFlow' track: This track contains the MelodicFlow plug-in.This will push the melodic rhythm notes to that track.

'Melody' track: Set the Midi To box to the 'MelodicFlow' track.For each instrument you will need three tracks: A track which contains the notes of the melodic rhythm (in the image: 'Piano Melody'), a track which contains a MelodicFlow plug-in ('Piano MelodicFlow'), and a track which contains the 'real' instrument and the effects etc.This is important for solo/mute behaviour. Put a simple piano instrument on the 'chord master track' and turn off the Track Activator (purple).The 'chord master track' (yellow) contains the chords.
