Converting midi tracks to real instrument tracks
Alright, now on to question #2. This one's more of a general question concerning optimizing performance. I've been recording on garageband for a few months now and have made a decent amount of songs with between 16-28 real audio tracks. I've been able to record drums, drum machines, guitars, synths, and bass(not all at once) ran through a Roland Digital 8 Track for multiple inputs with minimal delay. The only time I've experienced the problem where it stops mid song and says "too many simultaneous notes" has been when I'm well over 20 tracks and adding EQ's, etc. to each track. Recently we've tried to introduce midi to our setup by using controllers and I'm having problems. I understand that midi tracks have a different timing, and take up more memory (at first I thought they required less); but it's gotten to the point where I can't record for more than a minute without a stoppage when I only have 3 real instrument tracks and am trying to record a midi track. I've tried messing with all the settings in preferences with no luck, will converting those midi tracks to real audio (like my first question) make much of a difference? Also, in the future I'm planning on getting a Firewire or USB Audio Interface and Pro Logic; would this even make much of a difference? Or does all of this come down to processing power (meaning it's time for the dual intel processor)? THANKS FOR ANY ADVICE, SORRY THE QUESTION'S SO LONG
