At this point the DMUX board should be under production; however the issue with different libraries for the SMD ICs made me wait until the components arrive prior to sending the board for production. In the mean time, I decided to make a few modifications: now, Ground, +15V/-15V, +7.5V/-7.5V and Noise are all sent to the Voice Boards thru the same connector, making wiring cleaner. In the original design these are divided in two connectors. Also, connectors between different boards now have matching pinouts. For some reason, in the original Memorymoog, pins, say, 1 to 5 in one board would connect to pins 3, 2, 5, 1 and 4 in the other, making for pretty confusing interconnections. Now, pin 1 in one board goes to pin 1 on the other and so on. Oh, and rounded the corners in the boards!
Made an effort to reduce the number of vias in the boards by routing the traces as efficiently as I could. In some baords I could eliminate some 50 vias or more.
