I am debugging the Frac VCA (MOTM-1190) which is the 'core' for the MOTM-130
Pan/Fade VCA.
Happy to report this is a cool module:
a) the input has an "overdrive" so that at full level, a "warping" THD will be
present (triangles getting 'sin-ed')
b) the output side has a 2-transistor 'gentle clipper' for rounding of signals
above +-6V pk-pk
The design uses no OTAs (like the '110 and the '190). I will run plots of
frequency response and THD later this week.
The Frac version does ∗not∗ pan/fade but the MOTM version will.
Hats off to JH for another winner.
