Combine a player and MIDI track to drive a single instrument
I'm using Ujam's Amber virtual guitar plugin driven by a Logic keyboard player track. It works really well, but Amber uses key switching and other modifiers to control playback params dynamically, for example altering mute amount, strumming patterns, etc. The problem is that the player track provides the only input to the plugin, and thus I don't have an opportunity to inject the control keys.
Is it possible to run a MIDI or software instrument track that provides the key switch controls in parallel with the player track, and merging the output of the two before sending the data to the plugin? Perhaps by stacking some tracks? I know I could do it by converting the player track to MIDI and then adding the extra data manually, but this is really cumbersome and means I lose the controls provided by the player - for example I may want to re-use the same player settings in a different region, but with different keyswitch settings.
