I am the one this interface was designed for and I have found it exactly what I wanted. Mind you if I change my mind I might be trouble but I investigated alternatives and found this device just so valuable. It gave me 2 manuals of 61 notes each, pedal board of 31 notes, stop control of 32 stops and one variable volume control for the Swell control, and a number of Program Change controls - which are unused at this point in time. That was just what I asked for and at a cost significantly lower than using a Midi Merge device. One Midi output feed to the computer.
All I can say is I'm very pleased. Jordan Petrov programmed the device to suit my needs and he could probably do the same for you if you needed something different. The payment system using Western Express was OK and Jordan was most reliable in his supply even to this side of the World in Australia. Sorry this reply is rather late but hope it is still of use. Good luck. Brenton.
