Hi I'm a newb, looking for help with my multimix too.
I've had so many problems, and the forum has helped so much (and Alesis technical support has not!). I am unfortunately in the UK so haven't been able to speak to them by phone but their emails have been very scarse and very slow!
The first problem I had was with my firewire card. I purchased a new TI one, and can now record without it skipping (which was my first problem).
I have a PC and a Laptop. The PC was built for recording music and the laptop for browsing the internet, they're both of similar spec. (1gb RAM, 40Gb SATA Hard Drive, AMD 2800 processor, Service Pack 2, NET Framework 1.1 etc.).
Strangely, everything works perfectly and as it should do on my laptop (4 pin firewire) but not on my PC (6 pin firewire).
The problem I have on my PC is playback, recording is now fine.
On my PC, I've set it up with exactly the same settings as my laptop, hoping it would work. I've tried in both modes (WDM and ASIO). In ASIO, it won't play at all (just freezes when I click "play"), and in WDM, it works for a while but then it just stops, and it'll only start playing again when I go in to the Multimix control panel and either click "Set Clock Master" or change one of the other settings and then change it back. Then it works fine for a few seconds, and then it just stops again etc...
Very frustrating, and very strange - how can it work on my laptop but not on my PC when they're both configured the same?
I bought my Multimix on ebay so cannot return for a refund. Am desperately hoping I can get it to work as it should.
I would like to help any others that have problems out there with this product as far as I can, as I've been fiddling with it for a week and learnt a bit!
I'm using Acid Pro 6.0 for recording
Many Thanks
Keith
