I recently upgraded to Lion because of my side-activities as an aspiring iOS developer (no iOS5.1 SDK on Snow Leopard).


Since then, I noticed that Logic Pro MIDI reactiveness has hit the bottom: hitting a key on my keyboard doesn't take effect as soon as expected, making it impossible to play live.


I went to Logic and Reason and made them run in 64-bit mode, this kinda improved the situation but it still is non playable.


Has anyone some idea of how I could make Logic Pro fly like... one week ago, in 32-bit mode on Snow Leopard?


For info, my sound card is an M-Audio Fast-Track Ultra, and I use a CME UF8 USB as a master keyboard, as well as an Akai MPD-26 controller.

Logic Studio, Mac OS X (10.7.3), 2TB Case-sensitive FS/RAID 10, 8x2GB RAM, EVGA GTX 2
