EXS 24 Logic Sampler Users Group

Has anyone figured out what the most efficient Mac/HD system for getting the
most out of EXS24 mkII is?  I'm not happy with the performance of my system.
I'm using the following gear:

Mac dual 450 G4 with 1 gb of memory.  I have an IBM 7200rpm Ultrastar drive
mounted internally and partitioned into 2 40-gb volumes as a secondary
internal drive.    

I have 2 external 120 gb WD caviar 7200 rpm drives mounted in firewire
enclosures which have all of my EXS intruments and associated audio files,
with aliases of all this in my Logic Audio folder on my boot drive
(factory-installed 30-gb Quantum Fireball--not sure what speed it runs at).

Running Logic Audio 6.1 using the "mac" Audio driver, and TDM.  I have an
old PT 24 system with an extra farm card.

I don't think I'm getting the performance I could.  I get system overload
messages quite frequently!  Every day, I wonder what I need to do in order
to get real performance from these incredible software tools--currently
hampered by lethargic hardware.

Tim, I'm assuming you're outputting EXS through the Mac's own audio output
because I can't see any other way you could be doing it.

You MAY receive better performance if you -

*Add better native audio hardware for native audio engine output.

*Get a faster computer.

*Check all your settings and make sure your system is well optimised.

*You don't mention how much ram you have. If you have less than 512 MB then
add some. A GB + is preferred.

Since EXS is a native based system your old TDM rig won't be helping it at
all. In general the best native audio system is the fastest DUAL CPU machine
you can get your hands on with lots of ram and at least one (this may be
enough) fast dedicated audio HD - preferably not on the PCI bus - meaning
not SCSI. IDE (internal) or external firewire is fine. The best audio
hardware (no flames please) to support this MAY be the RME HDSP system since
it's been constantly reported as having less CPU drain than any other NATIVE
based hardware and exhibits industry standard (lack) of latency.

If you optimise your Dual 450 and run good audio hardware and plenty of ram
you'll get decent performance. Drive speed is not too much an issue since a
cheap 7200 rpm IDE drive will give 48+ tracks no problems.

Hi Tim,

Make sure you have the dual processor option enabled in your audio hardware and drivers. It may be that, because you are using an old D24 system, you may have to have it unchecked.

If you can run with it on though, try putting an  I/O plugin on some of the EXS tracks. This will force them to run off of the second processor, and thus should increase your performance. You need to set the I/O plugins inputs and outputs, but can then just bypass the plugin. It just needs to be instanciated in order for it to do it's work.

How many voices are you getting? Are you streaming them or running 
them from memory?
