That often gets called a "skew" control. I've often seen things like it on
LFOs (i.e., the Korg MS 'Modulation Generators'), but to my knowledge not on
an ∗audio∗ oscillator (Serge may have something that does this, I don't
remember).

I could be wrong, but I thought there was talk of a "shape" control
something like this for the upcoming MOTM 1u VCO...?

I don't have my MOTM-320 VCLFO yet---is this what happens to the Triangle
output when you sweep it's Shape control?

I don't recall where I first heard about this idea / feature, but it sounds
really neat, and like the kind of thing that would be on a MOTM module.
There is a function I've seen that's sort of a PWM for triangle waveforms.
It sweeps the shape from sawtooth to triangle to reverse sawtooth smoothly.

Forgive the poor ASCII art, but this is the idea:
|\ |\ /\ /| /|
| \ --> | \ --> / \ --> / | --> / |
| \ | \ / \ / | / |


Any chance of seeing that on a future VCO? Is this technically feasable?
Or am I daft and its already around?
