Pentagon as Vocoder - No output

I right clicked in an audio track (audio already there)and inserted Pentagon. Left clicked on Pentagon and turned Voice Modulator to ON Inserted a Midi track and made Pentagon the output Selected a patch (tried multiple patches) on Pentagon Hit play and nothing (no vocoding, no original audio) Ideas? Thx, Mike F.

Yes, I just figured it out. I guess it should have been obvious that there needed to be midi notes in the midi track. It wasn't stated on any of the videos or threads but now that I've done that it seems to be working fine. Thx, Mike F.
