Dammit... Suddenly my VSTi's won't make a sound...

[skinnyj]

I'm using the latest version of Reaper. When I go to set up a VSTi MIDI track (ex: drums), I get no playback sound. It reads on the track and master meters, but there is no output. The track is armed and monitoring is on. This is frustrating, as it used to work fine. The only major change I can think of is that I've added the M-Track since I last tried something.

Thanks in advance for helping with my idiocy.

Okay... I don't know what I did, but they are working now.

did you not set the M-TRACK as the default playback device for that session?
