1) Enable 2 VIs to play drums from an external sequencer like the MPC.
Set the Buffer in Logic to 32 or 64 samples. Play back and listen.
2) Now, with the same setup, up the buffer to 1024 or 2048. Listen to that and take note of how the timing changes to something which is impossible to listen to.
Using Logic as a host for VIs on a separate CPU is not good beyond a buffer of 32. Not because of latency but because Logic is
1) Altering the incoming midi timing based upon the set buffer
2) Logic wont distribute the CPU load to multiple processors while in this mode.
Only way to get a good timing is to use the stand alone versions of the VIs and leave Logic out of it. The stand alone versions WILL distribute to multiple cores very nicely and they WILL NOT alter their incoming midi timing regardless of buffer size
