DP3 & 350mhz imac, buggy as hell Options

I'm running DP3 on a 350 mhz imac with 512 megs thru a midi express xt. I'm having serious latency problems when playing back a sequence and when inputing notes. This happens sporatically.

Should I upgrade from Mac OS 9.0.4 ? If so to what ? MacOS 9.2.2 ?

Also, if suggesting resolving possible extensions conflics, please be specific.

Thanks in advance

First, let me suggest that you use your extensions manager to make a set of extensions just for music work that has ONLY the extensions that you absolutely need to run DP3 or other music apps. This may help.

Second, I hope you are not using virtual memory. Virtual memory should never be used when working with audio or midi as it will slow things down.

Third, do you have OMS? Is it setup correctly?

The only other thing is it could possibly be your midi interface. Check with the manufacturer for info on system compatiblity and latency issues.
