Re: [PD] how can I clear [vd~]
I actually went the easy way and doubled the [delwrite~]. After adding the
delay time to the [switch~] off message it worked just fine.
This is because I have delay times of 20 - 50 ms for doubling notes. Since
note events are not happening any faster then that it is working.
Indeed, using higher delay times would still result in clicks. So Mathieu's
fix for [delwrite~] is the only real solution for this. I'm going to check
it out when I get some spare time.
I hope this fix will be added to pd vanilla's / pd-extended's releases!!!
Thanks for spending the time, Mathieu!

Re: [PD] how can I clear [vd~]
Oh, I agree. I'd much rather use [vd~] than hack a workaround. But I don't think all of us are in the level of compiling our own externals (I, for one, have never done it). I'm merely suggesting it as an alternative. It is a pretty simple workaround, though. If you use [poke~] to write, then the delay time is just an offset to the index of [poke~]. And then, as you suggest, one can use whatever object that employs whatever interpolation method one prefers. .mmb On Wednesday, February 2, 2011, Mathieu Bouchard ma...@artengine.ca wrote: On Tue, 1 Feb 2011, Mike Moser-Booth wrote: You could also just build a delay using a [table] as the buffer.
