BMC 019
This is a microcontroller based module that combines an Attack-Release Generator with a delay. It can be built in either +/-12V or +/-15V systems without any modification, and other than the pre-programmed microcontroller, uses no hard to find parts. When used with the expander from BMC003, it has voltage control over all of the parameters.
These merchants probably sell this module. Huh?
