In a recent thread at http://www.northernsounds.com/ubb/NonCGI/ultimatebb.php?ubb=get_topic;f=18;t=001427;p=2 I listed a full orchestra of instruments which I had loaded into 1GB of RAM on my system. Others indicated that they were unable to duplicate my results on their systems. I gave a detailed step-by-step listing of the RAM usage for each instrument in that load along with the RAM usage for the OS and sequencer.
I was talking to Alan Lastufka last night and we may have bumped into a clue concerning the difference in instrument loading characteristics between systems with equal amounts of RAM. We noticed that each instrument was consuming approximately twice as much RAM on his system as on mine. The only obvious difference between Alan’s system and mine is the type of RAM being used. I’m using DDR PC2700 and he is using RDRAM Rambus PC1066. His RAM is 4 channel. He is also using 768MB of RAM compared to my 1GB but this is irrelevant to the issue of load size per instrument.
Let’s try a little survey: Try loading the following instruments and check the instrument size readout in the player (below the “Keyrange” box). The readout should be the same as given below (these readings represent the actual size of the instruments):
French horn 2 Solo – 13MB
Steinway Piano Duo1 - 124.15MB
Alan got close to double these readings with his system. See what you get and please identify the type of RAM in your system. With enough information here we may be able to narrow the field of likely suspects. Thanks.
