S8T and others,

Depending on how poorly or successful this has been for you testers, you might have needed to adjust your 32-Bit Float setting in EXS24 preferences. It will improve performance at the cost of RAM (although whenever I play with it it always reports using the same RAM as before; maybe because it's 64-bit now).

So toggle that thing to the OTHER setting and see how it affects the results. It will be significant, one way or the other.

And be forewarned, doing so, may RELOAD the entire sample/instrument set that is up in the Logic where you change that setting (and it will be perhaps on relaunch of other because the pref file is the same for all of them).

I look forward to hearing results. i am very busy these days but am still loading sounds up and trying to get to some practical tests of my own. Although the theory is clear enough i can predict my systems potential.

> i tried copy/pasting it from one environment layer to the next only to find my midi wasn't getting through.

You move objects between layers by selecting them, holding option and changing the layer from the flip menu. All cablings stay intact.

You can't copy/paste a Physical Input object cause there's always only one of it. Might lead to unpredictable results, as you observed.

Another quite basic approach is to drag objects between two open Environment windows. But you probaly knew all that and i'm boring you.

i did not know that about the environment and appreciate now knowing it. thank you. the list of things i know is much smaller than the list of things i don't.

Evan

i will try changing the settings, but it is my understanding that they don't have any affect with VM turned on. but, again, the list of things i know...

cheers

what are your settings in EXS' VM? mine are set to fast, less. i can only guess that yours are higher because i am having no trouble loading 64 instruments, of which at least 16 are legato/performance set and at least 16 are ALL. my largest VM size is just over 3 GB (the actual RAM used really doesn't seem to actually mean all that much). ...


Nope... Mine have been fast and less since the last series of tests. From your other posts it seems like we have many settings in common, buffer size etc. btw- I've tried the 32bit float on and off, and it doesn't seem to matter as far as memory goes. It says it matters, but I didn't notice it.

A few quick questions:
--Are your Exs settings for SR conversion set to best or normal? Mine is best. I don't know if that would matter...
--Could this be related to Sample Merge? I merged with 2g settings and share mode.
--Maybe I'm just choosing more layered samples. I tend to prefer keyswitches and mod wheel layers rather than separate midi channels for each articulation.

On a side note... I just noticed something last night. I didn't realize the "basic" instruments were spread across whole steps and limited to two layers. I actually pulled out the "gasp" manual last night to check some things and that jumped out at me. Guess it didn't click before.

Even with the limited tests I did last night, I am convinced that this is going to work, and that finally I will be able to have the template that I need loaded. I would like to get some input on why you set up so many midi channels. For me, it seems easier to have a part on one channel. I record a rough part line with a generic articulation then go back and add keyswitches to add expression and realism. What is your workflow like using different channels for each articulation. Do you record a part and then copy the pertinent notes to whatever track has the articulation you want? This may be OT, but here’s why I ask. From the way I’ve recorded in the past, it seems like it may be worth it to build a few huge keyswitching instruments for each part or section, but if I’m missing something about the separate midi channels I don’t want to go to all that trouble.

Thanks for all your input and work on this! You da' man ... (though I have serious plans to conquer the universe with my 2 g5's Big Smile )

if you don't mind listing the 24 instruments that cause such a high RAM load, i will load them and see what my RAM figures are. i know that is a lot of work and if you don't have time, i understand.

my EXS setting is currently "original" so perhaps that is it. will test it and see. also, my samplemerges were 2000 and share.

i was hoping to try out using individual articulations because that way i could have each labelled in the master and quickly select it. i have never really been a keyswitch guy - pre VSL - and so haven't gotten completely comfortable yet with it. but i'm learning its advantages.

am off to try and learn more. will share results.

and i suspect you will conquer with the 2 G5s. i think that is going to be a very elegant solution.

also, like keyswitching, i keep meaning to actually learn the manuals as well. i just need more time.

thanks. i will get to that as soon as i can (today for sure) and return my RAM results. if there is a difference, we'll hunt down why.

and yes, so far it appears that the EXS prefs of sample storage and SR conversion don't have any influence on RAM load with VM enabled.

session sample rate appears to have a very minimal effect - there appears to be about 5% more CPU demand for 48K session as 44.1 - but that could just be the increase caused by higher sample rate than sample rate conversion. in the end, it doesn't appear to be enough to really make a difference.

cheers

You will recover about 3% CPU by QUITTING the finder. Not sure how I did it, but for the longest time I have that option. Simply look up QUIT FINDER PANTHER on Google. There is some modifcation or app that you run that permanently enables the option.

Every 1% counts!

Does it, Evan? Seriously, I think I'd rather be conservative and leave a little overhead so I don't have to worry when I'm working.

Well Nick, all you do if you want the finder on a whim is click on it in the dock. Freeing up 3% CPU couldn't be any easier or more menu/grapgically driven in nature.

well, i can't duplicate your full song because i don't have the pro edition of the cube - just the pro performance set. so, for example, i don't have your basic_all instruments for solo violin or cello.

so i tried to substitute with something close (in the case of those two, i chose double bass all and flute all).

but to the best of my ability i loaded up those 21 instruments and am at a Real Memory total of 1.46 GB, Virtual Memory total of 1.81 GB. can't imagine that your instruments are that much larger than the substitutes i used, so it seems like something else is going on.

fwiw, my EXS setting were SR Conversoin: best; sample storage: original (these settings seem to have no affect on RAM amount)

VM settings in EXS are disk drive speed: fast; hard disk activity: less.

have you tried resetting the VM tool in your autoload, then reloading the song?

ok

i had 12 logics open at once - 1 master, 11 slaves - with a total of 552 instruments loaded which required 25+ GB worth of VM space.

the bad news? well it took over a half hour to load and just having that many logics opened - not playing, just opened - had my processors pegged at 100%. for the record, they were also pegged with 12 songs opened with no instruments loaded.

so 12 songs is too much to expect. i think 4 at once is more likely (though extreme).

from what i've seen, the only setting in Audio Driver prefs that really affects performance is the Process Buffer Range. having it set to large improves CPU performance for slave logics (though not by a lot). nothing in the EXS prefs seems to have an affect.

with one slave logic, i found setting the I/O buffer to 64 was fine. not sure about multiple logics. but each logic app can have its own buffer setting.

anyway, it looks to me like 1 or 2 additional logic apps with 64 instruments in each is definitely doable on a G5 with 8 GB RAM.

not going to be loadind the whole library anytime soon, but this is definitely an improvement.

well, everything will end up being a trade-off. do you want to load more instruments or play more at the same time?

i can easily load 6 logics - 1 master, 5 slaves - with a total of 290 instruments (which use almost 13 GB of VM space) available with a quicktime movie and still be able to select and play any instrument. of course just playing them back takes around 70 percent of the CPU, but still there is a surprising amount of room for composing.

anyway, the big bummer so far is the latency. while it seems that an I/O buffer of 128 works with all 6 songs, just that slight delay without the I/O plug in is a disappointment. and the I/O plug in, when employed a lot, does cause major CPU penalty.

i tried what i could think of to get around the latency to no avail. my brain is fried so i'm off for the weekend. unfortunately it looks like my testing time may be up for a while.

anyway, if you wanted to use logic/EXS/G5 as a gigastudio replacement, you could most likely have 300+ instruments available at once, of which you would probably be able to stream about 90-100 at once.

but for the latency, it could be great.

in the end, using the I/O plug, i suspect one additional logic will be about the limit on a current G5. all in all, not bad. and it just might leave enough room for Jack to work.

Well that's about what I expected. Around 300 Instruments. I am about to start a film and will try to see if on a G4 Dual 1.41Ghz, which is what I have, will benefit by running a SECOND logic, but I doubt it. Especially with how I like to load ALL instruments, I'm sure I'll already be pushing my limits.

stupid8track,

Sorry for the delayed reply... had a busy weekend. I tried your suggestion about resetting the VM, but still get similar results. Thank you so much for trying that song load. Something weird is happening. If you agree, let's try something very simple to maybe see what's going on here. Today I loaded only one performance instrument and compared the before and after TOP readings. If you could do the same with this one instrument, then perhaps we will see if there is something very different in our settings somehow.

The instrument I loaded is:

VI-14_perf-leg_p+porta_f (not merged)

Before the load TOP reported logic Vsize at 349 mb
After loading the one instrument the Vsize is 551 mb

Total instrument Vsize 202 mb

I'll be interested to see how you compare.

VSIZE on logic boot = 511 MB
after addition of 1 stereo EXS = 516 MB
after opening VI-14_perf-leg_p+porta_f = 710 MB

this was the unmerged, original VSL file.

Thanks S8T,

That helps a lot. We are just a couple of megs different in loading size. I'm going to guess that our other load size difference is choice of instruments. Perhaps the logic basic load difference is because I am set with minimal audio tracks.

I'm working on templates and large keyswitch instruments as I have time.
I have noticed the pro edition is substantially larger due to half-step samples, velocity layers, etc.

Here is a workflow idea that I am leaning toward:

• Building a basic orchestra template with fewer articulations for general composing. Work out arrangement, tempo, voicing, etc with this template, then bounce to PT.
• Building more detailed templates by instrument section including most all available articulations and replace section by section adding expression, realism etc. Then bounce each section to PT replacing the basic mockups.

I wish that you could load EXS instruments with program changes. (if there’s a way to do that, then I missed it somewhere). Then you could have several logics as instrument templates and let your master midi song set the instruments in each logic. It seems that having a massive “all available” template is still out of reach. I don’t like the logistics of having to save at least 5 different songs for every one I’m working on, but that seems to be what will be necessary. It appears unlikely that any template setup will cover all the bases, but we are sure a lot closer than we were just a few weeks ago!!!!

At least you can *copy* a loaded EXS instance in the audio config window inside the same song, so you don't have to navigate twice like mad each time to get near your desired preset.

Hi all, Hi Evan,
Maybe it's time to do a "resume" of this discovery !!
What to do precisly, how to sync those LogicAudio, how to retrieve all those EXS24 outputs etc...

enormous thx you BG ( big Gourou)
