I sometimes get a very annoying and loud tone from the DirectSound and ASIO drivers. There is no way to stop it but closing the application using the driver, or if no application is using it, to restart Pulsar. It happens most often, but not exclusively, when using Logic. The tone sounds like a sawtooth around 500Hz. I'm using WinME, Logic 4.7 and Pulsar 3 software. I've been considering reformatting and starting fresh with WinXP and SFP 3.1a though.

Any thoughts on the matter?

XP + SFP3.1a is very, it has removed bunch of bugs for me, and ergonimy is now alot better. The LIVE BAR is a very good thing.

Go for it, and update. But for XP, make sure you have LOTS OF RAM... With enough ram XP is very very good.

well,maybe a good description of what you're doing from nose to tail (including master/slave relationships) would help.actually,rereading your post,it sounds more like grounding....

Actually to me it sounds like you software-wired yourself a feedback loop... careful about wiring something through a mixer in Pulsar and also having audio monitoring enabled in one of your programs, or you'll get LOUD feedback. :smile:

Well, it can't be feedback because it happens with the DirectSound driver as well as ASIO. The only software that uses dsound on my computer is WinAmp...

Alright, I actually reinstalled everything cuz I upgraded to XP. I still get the same problem. The buzz tone is emitted from the ASIO driver at random moments. I can stop it by launching Logic (or any other app that uses the ASIO driver). But then, sometimes it will start when Logic is running, then I must close everything to get rid of it. It's definitely not feedback nor a grounding problem. It's a loud tone similar to a sawtooth oscillator. My Pulsar 1 is master, an Alesis AI-3 is slaved on the spdif port, not that that matters much I would think. My computer is a Pentium 3 700mhz with 512mb of P133 sdram. Any clues? Thanks guys.
