[PD] windows latency down to 15 milliseconds

[PSPunch]

asio4all is certainly a nifty program.

I'd like to share a story regarding this application I thought was
interesting.

A few months ago I purchased a MIDI controller by Alesis which came with
a soft synth. As far as I know, most soft synths have pages in their
manual explaining methods of reducing latency on your sound card.
Adjust this buffer, increase value if choppy cause you've gone too far,
else just give up and go for a better card... ya-di-ya...

Same with this Alsis product? No...
The manual just noted links to asio4all as a solution.


This application (at least the version I have installed) has extremely
political messages in its GUI. I hope it does not effect consumers
impressions towards Alesis.
