Hi all,

I'm currently working on a project where I'd like to store waveforms in tables or arrays which I could then use with some kind of line objects as amplitude envelope generators for triggered events.

I've been able to figure out how to create break point style tables via the documentation (like a standard ADSR), but I'm wondering, is it possible to generate tables/arrays using exponential/logarithmic curves?

I'm thinking of these as similar to the kinds of unipolar tables that are generated using the GEN08, GEN05 families in Csound, that are read with an oscil1 or phasor.
With this approach I'm hoping I can simply swap tables in and out of different patches when I need them.

I'm fairly new at Pd and Csound and have only been studying them for about a year, so if its something obvious or simple I apologize.

Thanks for your help!!

I believe this might help:

Whoah thanks!! Lars' bezier curve patches help alot. That's really close to what I was looking for. He mentions in his post that he's going to work on a version that computes several points, which would essentially be able to create the envelopes I was envisioning for my project.

Unfortunately my math is not very good and I'm having a hard time trying to follow the design, but will work on it.

If anyone else has enveloping design/implementation suggestions using tables/arrays or otherwise feel free to post.

Thanks!
