U can tweak a little bit the buffer, but then u get a slight delay, (which doesn't happen in cubase on acount of its PDC - Plug in Delay Compensation), 2 b able 2 get more plug ins running.... It depends a bit but I am using mainly the eq. so u can have about 20 eq+ 1 reverb+1 delay+ 2 comp/lim.... after this U'll still have some space but not all that much!
