Hi and thanks in advance for any help.
I recently picked up a used Slim Phatty for strictly control voltage use (no MIDI at all).
The control voltage source works perfectly (1V/oct adjustable), but the Slim Phatty needs 1.166 V to play an octave. In other words, feeding a 1 V change into the Phatty yields an interval of a minor seventh - one whole tone off. The Phatty requires 125% more than spec’d.
I searched and tried suggestions from other Phatty tuning problem threads (latest software, warm up time, all calibrations and resets, autotune off and on), and there was never a change. MIDI pitch tracking always worked correctly, only the CV pitch input is way off.
To reiterate, MIDI control in not an option, and creating a voltage expander to increase 1V to 1.166V is not a useful solution.
Could anyone help with something I’m missing here?
Thanks.
