Hz/Volt conversion/calibration (for MS20) - Airell - 11-18-2023
Hi there,
From other posts and the manual, there is no separate 'Hz/Volt' calibration, right?
When measuring C-0, it's 0v in 'V/Oct' but 0.25v in 'Hz/V', C-1 is 1v and 0.5v resp., until C-5 is 5v and 8v (C-6 is out of the volt range for Hz/Volt).
The doubling in Volts is 'relative', there is no there is no 'offset to tune'. For instance, 0.5v and 1v and might be a C-1 and C-2 on old gear X, but a B-1 and B-2 on gear Y (on my Vintage MS20 case). Not a big problem, I can change it by detuning the MS20, but there is no such setting on the NerdSEQ, correct?
Cheers, Airell

Correct. There is no specific calibration here. You could add a fixed offset using the mappings of the upcoming firmware and output from another output. It would mean you use a 2nd output but I think at least it would do the job. I think I spent only attention to it when I added the Hz/V functionality and since then nearly no one ever asked for it.

Ok, no problem.
Maybe I can use the calibration screen with the idea to 'offset' a channel from there by changing the values?
I assume the values there are 'pre-Hz-conversion', so it would (for my case) only be only a ~2/12th of an octave offset (from B to C).
So, setting the track to Hz/V, calibrate in the calibration screen, measure result from instrument with a tuner. That could do it?
When using mapping, could adding the Mod output of the same track to CV out via a mapping do it? I guess there is no 'adding of a (dummy) value' via mapping? Haven't seen much of the upcoming firmware yet.
Otherwise I still could offset (detune) on the instrument itself. Loving 40-year old technology
