I have a Norwich organ which dates from 1990 and uses the Musicom system. The tone generation side of the organ has expired (not a problem as I want to use an external tone source) but the capture system remains intact and workable. The organ is 2 manual and I would like to add a third manual with 8 stops (for which I have matching drawstops ready to go and compatible keyboards) My questions are:
1. There appears to be space on the capture boards to accommodate the extra 8 stops, so should it be as simple as wiring them in? The boards with Darlington transistors appear to have selector switches at the bottom to ‘channel’ the system.
2. The Musicom system uses 8x8 matrix for scanning keys and pedals. It is possible to add midi to the existing system easily or is it best to bypass with a stand-alone encoder?
Thanks in anticipation
