Can anyone advise a set-up to allow the ndb pipe organ library to be played live, with real-time registration changes etc? (I am not up on the use of program change messages in Gigastudio) At this time I'm just using an M-Audio Keystation to access different loaded sounds via its 4 zones, with a Berenger midi-pedal to allow volume and crescendo effect with its two expression pedals. This works fine, but is restricted and a mental challenge when re-setting for a new 'bank' of sounds.
