"Aaux card for the Buchla 208 / Music easel.
It's a 16 step envelope trigger module which offers drum computer like step input for two different Envelope outputs. Here a brief description:
- 16 three way switches, up selects output 1, down selects output 2
- Output is a simple envelope with only decay with a potentiometer and a CV input
- Length can be set to 16 steps or 8 steps, in which case it's basically a dual 8 step envelope trigger
- Sync input for syncing the Buchla 208 pulser to an external sync source
All in all a very straight forward card to use, but still a very complex card to build consisting of a 4 layer PCB behind de frontpanel, a 2 layer main pcb and a backpanel, sandwiched together. The 4 layer pcb and the 2 layer main pcb are connected via a total of 28 pins divided over 6 connectors."
