steve - what you're missing (and paul s. is missing) in describing it
as pull-OR-push is that both are important:
HDR:
every fragment we *push* samples to the plugins
and we *pull* samples from the hard disk
Real-time FX:
every fragment we push samples to the plugins
and we pull samples from the plugins
Software synthesis:
every fragment we pull samples from the synth
so its really pull-AND-push.
