Hi Rich,

I just tested it, and it looks like MIDI Thru will only play through the Default Synth, sorry. I'm not 100% sure if it's supposed to work that way or not, but I'm reporting it as a bug now.

Sorry I didn't have an immediate fix for you. If you need help getting your ASIO driver working, feel free to give our tech support line a call tomorrow, 1-866-983-2474.

Thanks
