Track and take envelopes

1) GetEnvelopePoint and InsertEnvelope point work only with track envelopes. Trying to find something similar for Take envelopes. For example for now I can't write a script like "copy/paste" take envelope points. 2) Can't find how to show/hide track envelopes by name. For example I write script "copy/paste" take envelope points, I have nearly all what I need, but I don't know how to show certain envelope on track

You can hide/show track envelope using the SWS extension API. Look at my Hide envelope script in my script pack. Sure, the envelope have to exist first. I don't remember if it works on takes. Try and tell us :P

here is the script. you may find infos in it. :)
