The minimum is 4ms, but I set this by comparison to my Odyssey, 
there's no reason they couldn't be tweaked to run faster. The 
response is exponential and computed at the sample rate, so I believe 
they should be bang on.

The architecture I've gone for isn't quite a pulse, it's 2 osc / 
filter / amp, with 2 LFO, 2 env and fully patchable modulation. I 
guess I could build a "pulse emulation" patch in the modular version 
I have in development with little difficulty.

Only if it's late compared to anything else...dialing in a small 
track delay in a sequencer isn't a problem, and 20ms (which I can get 
with 1 voice) isn't much more than nothing. For instance reality has 
a 17ms latency afaik.

There's a v1.5 beta of the demo version of VAZ on my pages with 
DirectSound support if you want to check this out.
