EXS 24 Logic Sampler Users Group

...when using exs24, a couple of MIDI tracks and a two audio 
tracks. This is on a G4 450 with 192mb RAM. 

Can't seem to figure out why my physical MIDI intsruments suffer 
DREADFUL MIDI timing, whereas is ESX24 has bang on?

Hope someone can help, sorry if this has been covered before...
