What type of known memory problems might exist between Logic (Logic 8 in particular) and either Kontakt 2.23 or Kontakt Player 2.23??
If there are known memory usage issues, what can be done to help/fix the situation??
My MacPro set-up: 2.66 GHz Dual-Core X's 2 5 GB RAM, 3 HDD's (one for programs, one for sound libraries and one for audi) and Mac OS X 10.4.10. I have not upgraded to Leopard (but did upgrade to Logic Pro 8). By-in-large, Logic Pro 8 works fine. However, I usually "network" the Logic sequencing projects with Muse Research's Receptor (version B) and/or an aging Dell Precision Workstation 650 using Musiclab's MIDIoverLan CP3. This has proven stable for me. For my most recent project, I decided to see how many instrument plug-ins I can utilize within the Logic Pro 8 program (without benefit of this "network" set-up). For this project, I'm using one instance of MusicLab's RealGuitar and 16 instances of Kontakt Player version 2.23 for a total of 17 instrumental tracks. The instrument libraries used are Garritan's GPO and JABB. With this many individual (not multi) track instances used, the activity monitor is showing high RAM usage. For some of the instruments, I could not use the KS choices (trumpet, trombone) because the extra RAM caused Logic to crash as I mounted more instruments.
I tried adjusting the DFD. Still, there remained high RAM usage and the occasional crash. For some of the crashes, I either got the endless colored spinning wheel or a message basically stating that there was no memory available for the DFD. I am no expert with the advanced workings of Logic and the DFD associated with the Kontakt plug-ins. But I am surprised that using just 17 instrument tracks with this newer Mac Pro computer (with 5 GBs RAM) is causing problems. Sadly, I am not an expert Apple user to be able to tell whether it's the computer or Logic or Kontakt. I suspect, though, its some kind of issue between Kontakt and Logic.
For my audio, I use MOTU's 2408 MK3. For my midi in-put I use M-Audio's Keystation Pro 88. I do not think either one of these devices are causing the apparent memory problems.
By the way. . . before I purchased my newer MacPro computer, I had a similar instrumental set-up using my aging Dell Precision 650 workstation with 2 GB of RAM using Steinberg's SX 3 program. I used the same GPO and JABB sound libraries. It did "challange" the Dell computer (I had to adjust buffer/latency settings to MOTU's 828 MK2 used with the Dell computer), but the computer didn't crash like what I'm experiencing at present.
I don't mind "networking" my computers together in order to use larger instrumental plug-in tracks. But I would think that given the "power" of my newer MacPro I should be able to handle more than 17 GPO & JABB tracks. Yes? No? I really do not know.
Given my current computer set-up, how many instrumental tracks (using libraries associated with Kontakt or the Kontakt Player) should I get??
Thank you in advance.
