I want to fill an audio array of 1024 samples with two exponential curves, a simple attack and decay envelope. While I can easily create the curves I want I'm have a hard time putting them into an array. What is teh best practice for loading different curves into an audio array using tilde objects? I've attached a patch that creates the two curves, if anyone can show me how to get them into the array one after another I'd be most appreciative. I've tried to use a delay object with a 4 millsecond delay but that was no good for me. Again, any suggestions of ideas are most welcome.
Rory.
p.s. as a Csound user I've got really used to using GEN routines. I'm happy not to have them in Pd as it forces me tothink about how the routines work, if I could only figure out how to get them into a table I'd be happy!
You may be interested in using [vline~], which allows you to easily schedule ramps all with one message. You may also be experiencing a problem with synchronizing your event rate delays to the writing of your audio array. Look into [bang~] for stuff like this.
Look at this patch to see if it suits your needs more.
I tend to do this kind of stuff with regular tabwrite and use [until] to do it all at the event rate.

maybe my abstraction [jmmmp/array-edit] (in pd-ext) can help you. play
around with it, or tell me about something you might want improved.

in pd there are no "audio array"s its just how you use it
curves, a simple attack and decay envelope. While I can easily create the curves I want I'm have a hard time putting them into an array.

i attached a version with delay. if you want to do other modifications of the array than just putting thing behind each other the problem is that [tabwrite~] has no possibility to write something at a specific point but from start. for that you could in your case use [tabwrite] - see above - you can play every array at audio speed. i also did an example with [tabwrite] as an example. i hope this helps. g.
