Bipolar performance knobs scale - 63 or 127?

I’m not sure what to set as the mod amount for performance knobs when they’re bipolar. 63 initially seemed to make most sense but then I realised this wouldn’t give the full range if e.g. the original parameter wasn’t set to 0/12 o’clock.

I’d like to be able to ‘transfer’ settings to the original preset when I find something nice using the performance knobs, and I’m assuming that if it’s set to 63 then you could simple add/subtract the perf knob amount directly on the preset to copy/save their effect to the preset.

Just wanted to check if any tips/preferences about this?

I’d choose my favorite setting, then adjust my ideal depth, compromise between negative and positive max.

I’ll give it a try but might standardise on 63 so I can apply changes to presets. I tend to use the performances as quick ways to edit/come up with new sounds more than ‘performance’ so this will probs make it easier to work out changes to save on the original preset.
