I am a young musician in a band called 41 Marquis (www.myspace.com/41marquis www.purevolume.com/41marquis www.famecast.com/41marquis) looking to do some recording. I just got a computer built with 4 gbs of ram and a intel quad core processor. I also own a Peavey 16 channel mixer (non-usb). I have the chance to get the M-Audio Fast Track Pro USB Interface to line my mixer through and also get Sonar Home Studio 7 Xl (worth approximately $350 together) or get the Focusrite Saffire firewire interface that includes Cubase Le with it for about $450. Which would be better to do? Is Cubase Le a relatively good program? Were are mainly just looking to produce some good sounding demo songs to post on our myspace.
