Greetings everyone! I have been reading alot on the forum about Logic and Mainstage. I am currently using a very old version of Sonar on a very outdated machine. I am looking to use a laptop to play back multiple tracks and output them to 8 outputs of a MOTU 828. We no longer have a bass player and would like to run bass plus some sequenced keys, harmony vocals, and extra guitar parts. Our sound guy would like to mix each channel as if it were a live performcer on stage. We play in the neighborhood of 40 to 50 songs per night. Here are my questions: 1. Will mainstage load and run 8 tracks of playback through 8 outputs reliably with that many songs? 2. How big of a machine should I be looking to buy? 3. Anybody gone from a Windows program to Logic? Do you like Logic better and why? I know this is alot of ground to cover but I want to make sure I'm investing in the right tools for the job. Thanks in advance for your advice!
