@Lindon That is a good option. Thank you for the suggestion.
I had thought about it. I guess the main reason why I don't go that route is that I like to keep envelope independence. I have things set up in a way that independence plays a role in an effort to produce uncommon textures. The other thing is that the idea of having different types of envelopes stacked over each other for a single purpose still doesn't sit well with me. I can't exactly get it to behave the way I want. And I'm not sure, but I think there isn't a way to control hold, decay, and sustain stages for the table envelope. So the whole thing just becomes too convoluted.
I would still like to have mono envelopes. Interesting sounds can be produced that way. But I think this may not be the right project for all that.
