THE ULTIMATE G5 8GB RAM LOGIC SYSTEM
I want to build the ultimate 8GB RAM Logic system. Klaus Bidault says he sold 
his 20 Gigastudio Pcs and now just uses a Mac G5 for all his samples.  How 
can one Mac G5 replace 20 Gigastudios?

On the VSL forum, Steve Von Kampen posted results of trying to utilize all 
8MB of RAM he had in his Quad using 4 MBs for Logic 7.2 Pro/EXS24, and 4 
MBs of stand-alone VSL VIs, but found that the VSL VIs leaked ram.

Is there a way for one G5 Quad with 8MB RAM or one G5 dual with 8MB RAM 
or two linked G5 Duals (each with 4Mbs RAM) to fully utilize all 8Mbs of RAM 
without leaking?

Has anyone tried:
1. All Logic systems, including Logic Pro 7.2 can only utilize 4 Mbs of RAM, 
running 128 EXS24s.  Anyone tried using 4 Mbs RAM to run Logic with 128 
EXS24s—and the other 4Mbs RAM to run the EXSP24 sample player as a 
stand-alone VST?

2. THE EXSP24 is a VST--which is limited to 16 MIDI channels.  Anyone 
opened several instances of the  EXSP24 stand-alone using IAC to access 
128 MIDI channels?

3 Both the EXS24 and the EXSP24 are extremely efficient RAM users.  Has 
anyone built an EXS24/EXSP24 equivalent of the VSL Vis that used only VSL 
EXS24 samples (not the VSL Vis) – but didn't leak RAM and could fully utilize 
8Mbs of RAM?  The VSL Vis basically offer 144 cell matrices.  I've never done 
it, but has anyone built one single EXS24 instance with 144 modulations?

So you could have 
one EXS24 instance with 144 string modulations
one EXS24 instance with 144 Wind modulations
one EXS24 instance with 144 Brass modulations
one EXS24 instance with 144 Percussion/other modulations

This takes advantage of the EXS24 uniqueness as a sampler—it only has to 
load samples once, so:
a.  you could load one Full Strings sample from Garritan,  VSL, Sonic 
Implants, and just using that one sample set tweak them via modulations 144 
different ways. 

OR:
You could build one single super EXS24 instance with:
STRINGS: 32 modulations via controllers
BRASS: 32 modulations via controllers
WINDS: 32 modulations via controllers
PERCUSSION, ETC: 32 modulations via controllers
This would be one super EXS24 instance that functioned as a super sampler.  

I'm thinking aloud, need your help:  The VSL Vis are nice but expensive, 
Kontakt 2.1 has excellent scripting, Gigastudio VST will be  interesting—but 
the EXS24 is the most efficient sampler because 1) it only has to load an 
instrument and sample set once and 2) you can combine hundreds of EXS24 
instruments into one super EXS24 instance and have an unlimited number of 
modulations.

Appreciate your thoughts, comments.

That was his theory, but it turned out to be nonsense - an  
intelligent-sounding term that meant very little in this case.

I'd like to help you set your system up, but with all due respect it  
would take too long to explain everything all over again. Please look  
at that same VSL thread where I explained how much RAM you can access  
on a G5 for the 15th time.

If you have any specific questions, please ask them. I'm not trying  
to be rude, but it would take 20 minutes to wade through your post.

I Don't know how well it works in practice, but I just tested the old  
idea of running two instances of logic simultaneously...

you cannot run 2 instances of Logic 7.2, as it comes up with an error  
message, saying another user has that application open....  BUT, you  
CAN run one logic 7.2 pro and one logic 6.4.2 Pro simultaneously...
but you have to make sure that the Logic 6  version doesn't try and  
open a Logic 7 song or autoload.


other than that, you can load sample libraries into the two quite  
happily past the 4GB limit overall....   each one is still limited,  
but the combined total goes past 4 Gb ( i have East west platinum  
libraries (largest 2 of each group) and some  big piano libraries,  
and BFD, and so on  loaded as i type.

444	 Logic Pro	maxhodges	22.90	16	2.80 GB	3.47 GB	1,842	205.91 MB	 
2.69 GB	1:09.41	409,709	296,568	
413	 Logic Pro	maxhodges	52.20	35	1.45 GB	2.04 GB	351	115.69 MB	1.46  
GB	14:52.09	1,239,761	437,696	


I haven't time to get really silly with it....    But in both Real  
and virtual memory these two instances add up to over 4GB.

and no crashes yet....

the system used is a Rev A 2x2GHz PPC G5 , with 6 GB of DDR 400 RAM.

can't speak about audio quality, as it's past 2 am here and i'm NOT  
in a soundproof studio  room, just working in my home office/work  
room/studio....  under my kid's bedroom.

Likewise I haven't really explored Midi and audio communication   
yet,  but I guess OSX Jack could move audio between them, and IAC  
midi would be fine....

I wonder if this might also be another solution to the issues being  
had by those with Quad core g5 PPC machines unable to wring the  
maximum grunt form their investments?


I'm not a vienna user yet, but saving hard towards it !

A lot was written about this a couple of years ago. In reality it's  
not a very stable or workable system. You run out of CPU, and it's  
generally a PITA to use.

For quite awhile I've been experiencing a problem when loading songs 
or templates that contain EXS instruments. Certain instruments will 
load as if the sustain pedal is in the "on" position, and only 
removing and re-loading the instrument will fix it. This happens even 
in templates where there are obviously no sustain events. I've had 
this happen with a variety of sample instruments from VSL, SAM, PMI 
and others, so I don't see any connection to a particular vendor. Has 
anybody else run into this? Any help appreciated.
