p5.Oscillator - how to get current value?
How is it possible to get the current value of an oscillator?
That is, within the draw() function, I want to sample the current value of the oscillator.

While you can getFreq and getAmp, I don't see a way of sampling output from glancing briefly at the P5.js-sound oscillator source.
For low frequency oscillators one workaround might be that you could compute a representative value using a known start time...?
Yep. I also didn't see any solution in the sound API. This is weird that it is missing. I come from Max/Msp, and it exists there. Any 'signal' can be sampled.
Computation using start-time, if problematic since the oscillation freq changes by the user moving the mouse, and I don't want to stop&start the oscillator everytime the freq changes.
Good thinking though (-:
I added a Feature request on p5 github. https://github.com/processing/p5.js/issues/1895
