Okay, let me float this one past you all: I would like to put together a new system for orchestral composition using East West Quantum Leap sample libraries (EWQL). As always, I want to do this as economically as possible. Keeping that in mind, here is an idea I would like the tech-savvy to discuss: The latest generation of quad CPU iMacs have a new feature: "target display mode". When activated, an iMac's screen can be used by another external computer, and any open and running applications on the display-donor system continue working. So... If a person bought two 27" i7 version iMacs, upgraded each with 16 RAM ($200 from OWC), one could use the first as the main system, spanning the desktop across both displays. On that machine (we'll call it the "left" one) one would run Logic and plug-ins. On the target display mode machine (the "right" one) one would install a dramatically pared down OS, a copy of VE Pro (a popular sample engine for VSL and EWQL users), copies of node-worthy 3rd party plug-ins, and several EWQL sample libraries (either on the internal drive or external drives using TBolt). Both machines would also be connected via gigabit ethernet so that a) the "right" machine can run VE Pro and feed the data to Logic on the "left" one, and b) spare CPU cycles on the "right" machine would be available for use as a Logic node by the "left" machine (whatever the system isn't already using to run VE Pro). Seeing that the i7 chips use hyperthreading, each machine reads as having 8 cores in Logic. The result would be a 3.4ghz 16-core 32GB RAM system with dual 27" monitors included for under $5k for the hardware. Yes, I know there are limitations to what can be done with Logic node sharing, and two 8-core machines do not equal a 16-core computer. But with everything I've heard about VE Pro, I bet this configuration would do some heavy lifting. Two Mac Pros without the monitors or RAM upgrades (running slower @ 2.8ghz) would cost more. iMacs cannot be expanded like a tower can, but with Thunderbolt a lot of future i/o external options will be available. Also, I hope the next Logic upgrade allows for stable 64-bit node utilization via all of the faster network connections: FW800, GBE, & TB. That would be an important consideration before moving forward. If Apple engineers don't fully nail that down, however, this system idea wouldn't be worth it. Reflections?
