Thanks gang! Yeah, it's the Pd array I am trying to emulate. Using LCD, I can make it work as long as I can specify the size of the LCD object and scale the drawing to it. That works really well for things like the 512 sample waveforms used in [cycle~]. See my patch below for that. Luke, thanks for that link! I, too, am no jitter expert, but that's pretty cool! I'm going to dig around in that one for awhile.
