Hi, Whenever I use my Roland keyboard to trigger the software instruments (via midi) in Garageband, I have severe latency/lag problems (so bad that sometimes it skips notes altogether). I am not sure how to correct this. Can anybody help? I have an iBook 800 mghz processor, 640 megs RAM. I am using an M-Audio 410 Firewire audio interface and a Roland ep7ii as a midi controller. I have already tried optimizing (reducing buffering) and direct hardware monitoring through the M-Audio Firewire 410. I don't think it's a monitoring issue anyway as the notes actuallly get recorded the same way they sound (which is quite terrible). I know using the software instruments require a lot of processing power so I tried using a firend's Powrboook (1gig processor) to do the same thing and there was no difference. I have also noticed that there is absolutley no delay/latency at all if I use Gragaband's on-screen keyboard to trigger the same software instruments so this makes me think the problem lies not with my computer or with Garageband but somewhere in my M-Aduio Firewire 410 or with my keyboard. I am switching to Logic as soon as it comes out but not sure if this will make any difference. Any thoughts, ideas or suggestions would be appreciated!
