Okay, I have several MIDI tracks being sent to a VSTi multi part. Trouble is although the MIDI is playing, and the audio is all set as per normal, I am getting no audio out from the VSTi, and indeed no midi input is seen via the LED bars...
 
If I connect an external keys controller and play the parts I get sound from the VSTi?
 
I cannto figure why I am getting no sound (or input) from the MIDI tracks.
 
Any ideas?
 
Thanks
 
Using Soundfont files and have now tried two VSTis Jeskola and SFZ+. Both of which load the SF2 files, and I can actually play them llive from the controller, but yeah, nothing when I try to send a MIDI file to them.

Please explain your routing of the MIDI tracks and the VSTi audio tracks.
