double_UG

i try to modulate the buffer playback speed with function. In the attched patcher

the function triggers curve~ witch playback the sample. If i have a straight line

from 0 0 to max max in function the playbackspeed should be constant. In the attached

pachter the playback speed rises at the end of the buffer. But why ? I can clearly hear

the pitch rising and the loop isnt round. So can anyone tell me whats wrong ?

Guess this has something to do with the curve mode of the [function]. Try my patch with [play~] instead of [index~] : it plays fine. then set the envelope to curve mode and replace [line~] with [curve~]...

The same happens in your patch with linear / curve mode for the envelope : it seems that in curve mode, what looks like a line already has some log / exp applied. I modified a few things (yellow objects). You had forgotten to send the setdomain $1 for [function]. Now it plays at the right speed. What I don't understand though is why there's some silence at the end of the loop. That may come from the use of [index~] but I've never worked with it...

strange thing, I made a test patch witch works fine in MAX Standalone, but not in M4L.
