I have an audio file containing three states : attack (from 0. to 

2889ms), then the loop (2889 to 10000.) , then the release. I wonder 

how, when banged, this file could be played with the attack part first, 

then stay on the loop part as long as another bang is received, then 

Is it possible WITHOUT risks (timing ? glitches ?) or do i have to 

emulates the ADSR the usual way (adsr~...) ?

not sure what you mean but doing what you say i spretty easy with 

groove~ - if you start at sample 0, define (with info~ ...) the loop 

then your bang switches to loop 0 and plays the file until the end...

groove~ - if you start at sample 0, define (with info~ ...) the loop 
points, and send message loop 1

well if you want your envelope code to work

sampleexact under all circumstances, you have

if the accuracy needed is not about the time point

when something starts, but more about synchronizing 

the process with the another process, you could

downsample the envelope stuff for 2 or 4.

i have never used adsr~ because it is too unflexible 

for my needs (and does not exist for OS 9) but that

would be a way to go. just try to avoid sending 

messages to start 10 of them "at the same time" - use

A last annoyance forced me to leave this "audio enveloppe" approach 

aside : even after doing a clean edit in soundforge, the loops still 

glitch (near unaudible but they're here).

By the way, i'm using this thread (i'm still a mailing list user...) to 

mention a few weird things i've discovered while doing this patch :

- info~ (on win) doesn't give the Sustain Loop Start, nor the two 

Release Start / End Points. Only the Sustain End. I assume this object 

reads the loop infos from an *.aif* file (which is not common on pc, we 

use .wav most of the time), so i've edited some .aif's in soundforge and 

saved these loops within the files, with no results...

- pattrstorage seems to be very touchy (still on win) : if you delete a 

pattr already bound to an object, or delete this object itself before 

deleting pattrstorage, you could say bye bye to your patch and go
