I purchased VB3 from GSI in 1974. I've been very happy with the sound but recently I've been experiencing a problem. Sometimes I will insert an instance in a new project and I'm unable to get it to sound with my MAUDIO controller. I am able to see the midi activity in the step sequencer and if I click on the note in the step sequencer it sounds. I inserted several other VST instruments and everything else seems to work. If I load an existing project that has an instance of VB3 in it, everything seems to work. I suspect I have something set wrong somewhere, but I can't find a difference between one that works and one that doesn't. Any suggestions on where to look?
