I was reading the forums on RME's website and I'm starting to even reconsider that option. Seems like a lot of people are having problems getting their products to work with the new Apple MacBook Pros.
Anyways, with regards to latency I've read that some DAWs don't calculate it correctly. I don't know if Live is one of them. It shows the input latency and output latency separately and adds them together I guess. That's where I got the 20ms time from.
I'm also using a seperate drive for my audio it is a G-Tech 200GB 7,200rpm drive. I have it connected to the sole firewire input on my computer.
I'd like to get more mileage out of the Mini for now, but I'm not sure if that is possible. If I load two soft instruments into Live and have them play a simple midi track my CPU usage spikes to 25%. I'm looking to have up to 10 instantiations of soft synths, drums, etc. in my sets. Either way I probably have to buy a new laptop because I'm not hauling a CPU, monitor, keyboard, etc. around to gigs.
Thanks for all or help and advice!
