I’d say it makes more sense (although that’s perfectly fine) to program the range that best replicates how the MS20 is calibrated - via its own keyboard - whilst it’s theoretically the same, the drift either side of the nominal range would make it tricky to set up based on those values if it needed a tweak
.
The MS keyboard outputs Midi 48 > 84 which is equivalent to C4 > C7
C4 is 1V
C5 therefore 2V, C6 therefore 4V
C7 is 8V
.
sure the ratio is theoretically the same (except there’s an octave shift)
.
If those settings needed a little tweak from nominal, i’d say it makes more sense to tweak 1V and 8V because the oscillator calibration is better within that specific range
.
If your MS is set up nicely then it won’t matter at all, mine wasn’t so i calibrated it (Nominal footage range is 8’) - it’s nice and easy to dial in these
C4 = 1V and C7 = 8V Hz/V pitch & S-Trig gate
- this also means the A4 keyboard defaults to the middle of the MS key range - that may well be the reason to offset the octave of the settings for the Analog Keys, but i’d have assumed it would offer the A4 default +/- one octave without using the octave up/down
