These instruments include Kontakt Session Horns, Session East West Hollywood Brass, Addictive Drums, etc - so when I load up a GM song (in GP?) which plays through the 1 GM VST, the other specific instrument plugins for that song will also load so I can add live elements. Requirement 2) one more performance layer is created on by using another keyboard controller that’s used to trigger VST instruments that play keyswitched phrases and loops in real-time (live) that are synced to the song’s MIDI tempo. Requirement 1) I also play other instrument VSTs live over each MIDI song backing track using multiple keyboard controllers running different VSTs and FX (ie piano, organs, lead synths, guitars, percussion, horns).
Note 2 (and 1/2) other critical live performance requirements i.e., are Roland SoundCanvas or Purity/Sonic Cat a good fit? Is there a different solution? I hope to use GP to que up sets of songs on General MIDI files that I will use as backing tracks and need a recommendation for a General MIDI VST (so Windows) that sounds good that will play up to 16 separate instrument channels simultaneously.
