[sdiy] Korg Lambda envelope

[David Moylan]

What I'm talking about is the envelope generation not the VCA section, 
that's taken care of elsewhere in a chip.  The envelopes (per key) use a 
global Attack and Release setting.  It's a strange topology with 
reversed diodes and I can't quite figure out how to decode it.  I think 
the diode resistance is being modulated

Have a look.
