You were right. I'm glad I asked about this.
In 0.38, under ASIO, I only get one option for output and for input.
In 0.39, it offers me the whole list. After I went down the list and
actually selected ASIO for both, I can get down to about 7 ms with
both input and output active and still run my sequencer.
Awesome. I'm on 0.39 from now on.
Incidentally, at least on my system, ASIO only runs with 48 K or 96 K,
there is no 44.1.
Thanks for all the info!

> the total latency should be a bit more, (256 samples for ASIO + 64 for pd's internal blocksize) / 44100 and maybe a ms or so for the DA. so around 8 ms. which shuld be acceptable unless youre a scientist.. in which case you can use the RT kernel, set the ALSA/jack buffer to 32 samples, and run pd-devel with the cb-scheduler..
