I am running Jamstix 3 on a pretty loaded system (Quad Core Q6600, 8GB RAM, Win 7 64bit, Separate HD for Samples). My soundcard is the EMU 1820 PCI with both PCI Cards and the external breakout box. I am running the Windows Vista 64bit drivers (Have not tried the new 64bit beta drivers) at 4ms and with the exception of the Jamstix samples not playing cleanly all the time, I am having no problems with any of my other sample/synth VSTi's. I noticed this problem occurring up to 10ms of latency, as soon as I move it to 12ms or higher, the problem goes away. The CPU even at 4ms is barely being hit so I don't really think thats the problem. Any ideas?

I could try the beta drivers but thought I would check here first.

Are you getting crackles?

Yes I am... Not on every drum hit, but often enough to be noticable. I would also describe it at times as sounding like some notes being choked off (not in the good way that closing a high hat or grabbing a cymbal chokes off a note). Hope that makes sense. Any suggestions... Oh I think I forgot to mention I am running it in the latest version of Sonar Producer 64bit.

Please increase LoD PreBuffer to 64k in the JS3 Options and see if it solves the problem.

I will try that tonight when I get back to my studio and let you know how it goes. By the way, the new drums sound great!

Here is the update... I tried changing the Pre-Buffer to 64K as you suggested but unfortunately I'm was still hearing those "glitches" sporadically. I tried playing with Priority and Enable Load-On-Demand settings without success and eventually set things back to where they were intially (Enable Load-On-Demand - enabled; 32K Pre-Buffer, Priority - Higher; Core Assign - Auto).

Then I went and changed the sync setting on the sound card from External Source: S/PDIF to Internal: 44.1KHz and that seemed to fix things. It sounds very clean now. I will keep experimenting and let you know if I encounter any further problems.

Thanks for the quick response!
