Hi,

I want to use PD to process the sound of my guitar in real time. The lowest latency i can get in Windows is arount 15-20 ms, which is a little to high for me.

I've been struggling with many linux distros, including Ubuntu studio 8.04 and 8.10, and Pure Dyne, but none of these seems to work properly on my laptop (i have a Dell Latitude 520 with 1 GB RAM and an Intel Core 2 Duo chip).

What OS would you recommend? Or is there a way i can get a lower latency in Windows? I have tried Jack for windows, but it's at an experimental stage at the moment, and i have been able to make it work...

I find this very frustrating... Pure Data is such an amazing application, but i can't make it work the way i want.

I've been able to get low-enough latency with Windows XP (3 ms, I think) using an Edirol FA-66 soundcard with a firewire interface. I think I also had to set PD's priority to realtime using taskmgr.exe.

Are you using ASIO driver? I get really low latency with my integrated card using Asio4All generic driver, as well as Edirol FA-101 firewire interface using its own ASIO driver. I've been running PD on Windows XP for quite a while now, and I'm very pleased overall.

My laptop is a few generations behind yours (Pentium M 1.6GHz) so you should be able to achieve even lower latencies using Asio4All.

Good luck!
