In the Woodwind manual there's an approximation of memory usage for each preset, matrix or preset. Here's a couple of examples:

Patch Ob2_perf_legato level 1: 979 samples/61mb ram
Matrix Ob2_perf_Universal level 2: 2165 samples/135 mb ram
Preset Ob2_preset level 2: 7073 samples/442mb ram

level 1 is std edition, level 2 is the extended edition of woodwinds II.

Bjarne, can I download the manual from somewhere?
I'd like to take a look.

well - its in the user area which requires access. Hmn - maybe CM or someone will send you a copy?

Anyway I added some examples in my previous post

Hi Henrik,

haven't tested this with Woodwinds, but I'm doing string stuff quite often which also requires 3-4 VI instances. I have 2 GB RAM, and when I load basic setups for 4 instruments (legato, repetitions, several single note articulations) there's still headroom left. If I want to do detailed work on single tracks when the rough composition's done, I bounce the tracks and then work on one VI after the other using the other instruments' bounced tracks for reference.

Kind regards,
David

Thanks, Bjarne, that's exactly the info I am looking for. If someone could send me the manual for Woodwinds I and II, I would be very happy.

oh - and another tip: Its straight forward to calculate the RAM usage.

Each loaded sample requires 64 kb of buffer in RAM so:
Number of samples x 64kb = RAM usage.

So loading the entire Woodwinds I extended version will require:
101,964 x 64kb = 6,2 Gb of RAM !!

Fortunately you don't need to load it all up to get working [:D]

Hi David,

Hm, it sounds like I should be able to work somewhat decently with Woodwinds on my machine then.

Wait, wait, wait - what??? Where do you get that figure?

According to my experience, if you load a 128MB instrument, it will use approximately 128MB of memory. You can see that in the Activity Monitor window on Mac Os X. Don't know about Windows, but it shouldn't be too much different..

You're both right ... 16 Samples take 1MB memory - and an instrument that requires 4 MB will not have more than 64 samples, etc.

Cheers,
David

Ok, then - it seems to me since we already know how much memory an articulation takes, it's very easy to know how many of them you can load [:)] ... no need for other type of calculation, isn't it?
