[sdiy] LFO range as equal tempered pitch modifier

[cheater cheater]

the problem with quantizers is that they don't do sweeps. They're fun
but an LFO with a permanently enabled quantizer is mostly useless
because it doesn't do what an LFO is expected to do, i.e. sweeps.

One way to do what you want is to take all the waveforms that get
mixed into a certain modulation point, normalize their mix to 1V p-p
(you can do it immediately since you know the signal amounts of things
routed to that input), and then multiply all that that by what ever
interval you want. Then you get to influence the relative amounts of
different things modulating your parameter but you always get the same
depth and therefore interval.

BTW, if you want discontinuities in an LFO waveform, it's enough to
have an extra bit that tells whether the transition should be linear
(interpolated) or an intermediate jump.

Cheers,
D.
