How to get the proper duration of an env in the Pattern context?

[scztt]

I posted a slightly more advanced example of how to use envelope passing in a real workflow here:

Envelope passing for Synths and Patterns

I work pretty heavily with Env’s passed as synth arguments - often I’ll just stick an envelope on every parameter I’d ever want to modulate, and then build a Pattern infrastructure to actually send the envelopes I want. Because it’s come up recently on the forum, and because I think it’s super powerful - I spent an hour and came up with a pretty basic but complete distillation of how to use Env’s in a Pattern context, dynamically building them from simpler parameters to enable all kinds of nice…

Among other things, I’ve got a post-processing phase in \finish where I ensure all my Env parameters are actually Envs, and set their durations to 1…0. Then later, in the synth, I rescale them back to \sustain… this is a bit of a simplification, but I think it’s roughly the right approach for scaling env arguments, depending on use-case of course.
