Logic Pro 9 plugin latency help please

[shreddersinc]

I have a song i've been working on for a while, but when I try to record midi from my keyboard it has alot of delay. I know this is from it (plugin latency)being set to all....but if i set it to audio and software instrument tracks the delay is gone but the project sounds horrible. I know this is from the busses I have set up.
So my question is whats the easiest work around? Do I have to delete all the busses?
I just can't help but to mix as I go along

Any help is appreciated
Thanks

Did you check the settings in your Audio Preferences the buffer?
You could freeze all the other tracks of your project. They will sound but wont be as demanding to you CPU. However IMHO the latency is more often due to buffer size. There is also the Low Latency Mode...
Do a little search into the manual under Latency:
