generalize replace/overdub switch about tidal-looper

[thgrund]

I think it might be a good approach to leave the rLevel at 1.0 and calculate the pLevel for overdubbing.
Do you have a source from which I can read a calculation, or on what basis is your calculation based?

I'm not sure how overdub is usually done. My assumption here is if you record a second loop over the first one, you should lower the volume of the first one in order to stay approximately at the same level and avoid clipping. So the formula I wrote is doing just that: if pLevel = 0.7, you lower the previous loop's volume to 70% while adding the new signal to a volume of 30%.

But maybe I'm mistaken, and one should simply leave some headroom when recording, so you have space for a few overdubs without clipping. In which case, my proposition does not make sense.
