These are my build notes for the NLC Double drum module.
I have a version of this in my NLC synth and it's a great module.

I plan to put this in with my Buchla. I don't have a face plate so will make that too.

From Andrew's notes:
"The core design was originally (used) in a Japanese DIY
magazine from the late 70s and was intended as a standalone, self
—contained device to be used with a drum kit.
The cool thing about this module is that it uses an envelope detector
so most input signals should trigger this.

I usually solder the SMDs first ... to both sides of the PCB.

The 22n SMD should be a 22k resistor?

BC547 --- NPN transistor - four needed --- the unlabeled trannies on PCB
BC557 --- PNP transistor - just two needed.... marked as pnp on the pcb.
