Has anybody else experienced audio breaking up when using an mxj~? Even the

simplest mxj~ object seems to make loud crackling sounds when I move or

resize a window. A bit gutting as I've just spent far too much time building

a bunch of effects! Should have done a bit more testing first. (Win Max

What's your CPU usage like? Crackling often indicates a resource shortage.

When you say moving windows - which ones? Max windows, or are you doing

When you say moving windows - which ones? Max windows, or are you doing 
Java gui things?

You're right it is a CPU thing. I'm not doing anything fancy whatsoever - for testing I've got an mxj~ object that simply copies the in to the out so the cpu reads more or less 0%, then I'll do something like minimize the patch, or drag the patcher window somewhere and the CPU shoots up and the sound crackles. hmm... does this mean I should really be doing this in C instead of Java?

I can't see any intrinsic reason why it should, but I'll admit to be 

being a bit mystified. At this point it may help to know some details, 

like os, java version etc. If you post your code, I can test here and 

see if I can replicate (or spot any boo-boos).

That would be great thanks. I'm using Win XP, Max 4.6.3, JRE 1.5.0.120.
