easiest way is to use a combination of a [line] object and some [delay] objects to control the desired changes in the output of [line]. also, its maybe worth checking out [vline~] object. i recall that iemlib has some examples of adsr envelopes using the t3_bang objects (allegedly more accurate..) but it's nice to make your own. ;)

I want to specify a simple adsr envelope; having looked at the help files on the line and line~ objects it seems that I can only specify an initialization value followed by one set of coordinates. Is there any way of specifying multiple sets of coordinates within one message or do I need to deal with each segment of the envelope seperately?

Thanks L

the t3_line~ object from the iemlib_t3 library can do this (it's part of the iemlib that isn't built into pd, i think), and all of the coordinates can be specified with millisecond accuracy.
