Hi All! With the advent of Logic 9, the ability to use more than 4GB of ram and new affordable iMacs that can be loaded up with 16GB of ram(!) I thought it'd be interesting to provide a 'benchmark test'. It reminds me of one I saw on the net a few years ago and is not necessarily scientific in it's measurement :) Here's how it works: 1. Download this Logic project: [url]http://www.sendspace.com/file/ytx28t[/url] 2. Quit all other applications except Logic. 3. Make sure you are setup as follows for our results to be comparable: I/O Buffer Size = 512 Process Buffer range = Medium Low Latency Mode = Off 4. Press play and one by one select a region on a new track and unmute it. When you are not able to play the whole Cycle region without the overload message. When Logic interrupts playback write back to this thread with the following info: - version of Logic (e.g. 9.1.0) - version of OSX (e.g. 10.6.2) - Mac details (e.g. MBP, 2.4, 2GB ram) - number of tracks successfully played back (e.g. 32) Do Not add or remove any plugins or change the presets ;-) Ok, let the benchmarking commence!

Wot? No one else wants to start? OK, I'll bite :) - Logic 9.1.0 - OSX 10.6.2 - MBP 2.4, 2GB ram - 14 tracks played back successfully.

Ok, Logic 9.1.0 OSX 10.6.2 iMac 24" 2.8GHz Intel Core Duo 2GB RAM 16 tracks played successfully! (But barely...on the return to the front of the cycle it failed within one beat.) Jamie

iMac 20" 2.66 GHz intel core duo 2GB Mac OS 10.5.8 Logic 9.1.0 16 tracks, crashed on 17th

iMac 20" 2.66 GHz intel core 2 duo 8GB Mac OS 10.6.2 Logic 9.1.0 running in 64 bit 16 tracks, crashed on 17th????? I have one third party plug in, BassStation by Novation. Novation tells me that this is 64 bit compatible, so why no change from 32 bit Logic (in Leopard) with only 2GB Ram? Any ideas?

27" iMac i7 4GB Mac OS 10.6.2 Logic 9.1 64-bit 38 tracks. All 8 cores were running. 7 touching red and 1 pumping half way to the red. Not bad! I figure this will improve with more RAM. When I get the full 16 I'll run it again and see what happens. Jamie

17 tracks played successfully, in both 32 and 64 bit mode. 10.6.2; 9.1; iMac 24", 4 gigs RAM. For me, so far, Logic prefers 32 bit mode. I ain't going to be paying €400+ to double my RAM anytime soon, either.

Hi Glenn, Thanks for adding to this thread. What processor is your iMac? You may be able to click the "edit" button to edit your initial post if you try within 10 minutes of posting. :)

2.66 ghz C2D.

Interesting... I have the same machine, Glenn. But I have only 2GB RAM in it and I was able to crank out 16 tracks. I would think your extra two would have given you at least a few more tracks! I wonder why that is... Jamie
