Hi, i'm using pd 0.40.1 on Linux and your patch is working fine... to improve your sampler: if you want to have a constant amplitude for the whole chunk , you should try to multiply your cos~ by *~ 10 and then a "clip~ -1 1" object : This causes no glitch but a quasi-constant amplitude...

Hi,

Is it possible to load up files "on the fly" to use in a sampler. When I try to do this with [openpanel] and [soundfiler] it crashes PD. Once, it crashed before anything was even playing. Is this any kind of known bug? Maybe an [openpanel] problem?

I need to do be able to load samples on the fly, for improvising with an electroacoustic ensemble... I'm using one of the extended test versions of PD, 0.39.2, WinXP.

Attached is the patch I'm working on. It's just a simple variation of one of Miller's test things. Also, if anyone knows ways I might extend it to make a better sampler that would be great... I basically want to play small bits of sample files, at random, without glitching when I shift the read point. I don't think this is the best way to do it, but DSP is not my forte...

Oh, I've never gotten the new GOP feature to work right, either. How the hell do I change the position of the red rectangle???
