Derive.Scale.Ratio
Description
This "scale" generates pitches which are ratios of the pitches in
another pitch signal, #ratio-source. The intent is to tune one instrument
relative another.
It's not a usual scale because there is no notion of scale degrees or
transposition or anything like that. The degrees are ratios, e.g. 3/2 or
-9/8. A positive ratio will multiply with the source pitch, a negative
one will divide. The source pitch is only sampled at the beginning of the
relative pitch, so if the source is moving the relative one won't move with
it.
