I could end up wasting an entire afternoon on this; I've been tinkering with accum, counter, += etc. But gen phasor is pretty simple, right? How can I reset a phasor to zero frequency (and phase?) after it has completed ONE cycle? I intend to send it a frequency (=length) value, it executes that ramp and then returns to zero and stops, awaiting a new or repeated frequency value. Here's a wrong example:

quick-and-easy-stop-a-gen-phasor-after-one-period

. . . . it's for a simple one-shot envelope generator source.

thanks to an old thread where vichug provided this (in a different context), and thanks to his annotations I hacked it.

It allows for a one shot 0. --> 1. --> 0. phasor ramp, that waits at 0. Now I can make all sorts of nice sample accurate envelopes.

Here is another slightly different version, I think it's a little better CPU wise.

another version with gate and retrig mode.

when retrig mode is 0, it allows the ramp to reach 1 even if it receives a new trig.

it's made with the codebox, but don't worry, it's not that complicated, and more practical.

well..; happy to have been unknowingly of some help at some point anyway :)

I tend to hold on to patches like these, never know when they'll come in handy, so thanks again.

Bertrand, those are very economical and transparent, many thanks.

there's one little mistake, for timing accuracy, you need to change
