It has been a loooong time since i last used GPO. I had to reload it which went OK but, there is no volume output.Each time i press a key the red marker ? activates.Using a powerbook and axiom 61..Any advice would be great.
I assume that you are trying to run GPO3 from the Kontakt player (v2) in standalone mode.
If so, have you configured your inputs/outputs from the Files > Audio / MIDI setup screen?
Did you push up the mod wheel? That controls volume on most patches. If you've got no idea, try the harpsichord patch; that should work straightaway.
