Two channel wavefolder + VCA
VCA Timbre is a module equipped with two channels of VCA,
where the response can be adjusted, and a Buchla-stylewavefolder (Timbre) on each channel.
The VCA outputs and Timbre inputs are internally connected,
allowing you to vary the input gain to the wavefolder and therebyincrease the range of folding effects.
These merchants probably sell this module. Huh?
