Hi SVONKAMPEN,
I did all tests on this machine: Power PC G5 2.5 Dual/6GB RAM/OS 10.4.6/Logic Pro 7.2.1
1)
I loaded:
K2 (2.0): 1GB (with Chamber strings perf-leg programs)
VI (1.06b): 1.67 GB (with L2 Preset Solo Violine and L2 Preset Flute 2) 2 instances
I didn´t encounter any problems. This setup worked fine.
After I added some more programs to Kontakt I got a message saying: "Memory is getting low" although there was still enough RAM free according to the readout in the activity monitor.
2)
For this test I updated Kontakt 2.0 to the latest version.
1 Kontakt 2.11: (loaded Epic Horns and some Chamber Strings, 28 instruments in total)
1,14 GB = memory readout from Kontakt GUI and the memory readout used for Logic (RSIZE) in the activity monitor showed 1,6 GB
VI (1.06b): (loaded Solo Violin Preset L2, Solo Cello Preset L1 and 14 more Vienna Instruments = 16 in total. It was not necessary to load content to all of them because you didn´t play all of them simultaneously. To get the mentioned amount of memory I decided to load two huge presets of instruments you suggested).
1,9 GB = memory readout for VSL server in activity monitor
I played a violin line, a cello pad and horn chords, but unfortunately nothing weird happened. Everything played back smoothly.
So, obviously I will have to do some more tests when I am back from my holidays.
Best,
M a y a
