[sdiy] Preliminary Living Vocoder BOM

[JH.]

Yes. It's designed to connect a Matrix, like the EMS 5000, but "only" a 20 x 
20 Matrix. (The EMS has 22 x 22.)
You can also use 40 jacks instead (20 Send, 20 Return, with the Return jacks 
normalized to the Send of the same channel.)
Channel attenuator potentiometers also go into that send/return loop - you 
wire them after the matrix or Return jack.
If you don't want to connect either, ju just put in 20 Jumpers on the 
connectors.
The connectors have a 3rd pin, where you can deed an external CV for each 
channel. This is basically the EMS 5000 concept. *And* you can use this with 
a set of 20 potentiometers for a filterbank function during silence 
bridging, like the Sennheiser Vocoder did.

Meanwhile thing is powerd up, and there was no smoke. It stlill sounds 
crappy, but it's just a matter of optimizing some component values. At least 
it's alive, and not still-born. :)
