I can't get my VST instruments to work in Band In A Box. I click the Plugins tab on the mixer, and assign a VST to slot 1 on the Melody track, but when I play back the track the melody is still playing on a midi instrument, not my VST instrument.

Is there something else I have to do?

When I click on the name of My VST in the track field to open the Plugins dialogue, I click on the keyboard of my VST instrument in the editor but no sound is produced from there either.

Any ideas?
