I've used Logic Platinum for Mac OS 9 since Emagic's version 4.x. I've been leery about making the move to OS X because of sluggish performance and plugin/hardware incompatibility and instability. I have finally heard enough positive feedback regarding Logic 7.1 to upgrade. Will my system be able to handle Logic Pro 7.1? Other than EXS-24 (and Reaktor for sound design), I don't use virtual instruments, but do a good bit of my mixing in-the-box. My setup is as follows: -Emagic Logic Audio Platinum 6.x -Emagic Sounddiver 3.x -Reaktor 4.x -Dual 800 G4 (Quicksilver) -1 GB RAM -2 Seagate Cheetah 10,000 RPM SCSI drives (one is 9 GB & the other is 18 GB) -MOTU 2408 & 1224 -Emagic Unitor 8 -Lexicon PCM-91 (connected digitally to MOTU system) -TC Electronic Fireworx (connected digitally to MOTU system) -TC Electronic D-Two (connected digitally to MOTU system) -Tascam DA-40 (connected digitally to MOTU system) -Many various external hardware synths, samplers, dynamics and effects processors -Mackie 32x8 I am purchasing/upgrading to the following: Apple Logic Pro 7.1 MOTU PCI-424 card (I am upgrading it to the PCI-424 through MOTU this week) UAD-1 Ultra Pack Waves Native Platinum Bundle (also upgrading from older OS 9 version this week) Most of what I do is techno. I would appreciate comments or suggetsions from anyone regarding what kind of performance I can expect with my system and or anything else that I should consider while upgrading my studio.
