MOTM

I will buy at least two of these.  This module will greatly help with
dynamic articulation of sounds.  I like the feature set including the
Velocity VC level, with a few suggestions...

I'd like to have simultaneous linear and logarithmic outputs - same FP real
estate and less cost than a lin/log switch or knob.

Two freely patchable attenuators works.  Another option is the Evos ADSR
type VC selector which cycles through all combinations of the four CV
parameters.  This requires a knob and 4 LEDs though.

You might not need both burst and cycle switch settings.  If you put a
pullup on the gate input, when you switch to burst/cycle without a gate
input you get continuous (cycle), if you have a gate input it functions as
burst.
