EXS 24 Logic Sampler Users Group

Being that the EXS24 is 64 voices, I'm assuming that if I have one 
sampler open that's holding down a pad using up 32 voices, the 2nd 
sampler I open will only allow me up 32 voices?  Or will each sampler 
I open up allow me 64 voices total?

Upon trying to use voice 65, what happens?  Is voice 1 cancelled and 
you able to hear the 65th voice?  Or does the sampler not allow 
you "steal" from the other voices?

Thanks!

64 voices per open sampler!

Put your EXS in '32 bit float mode' and you can play twice as much 
(total) voices, but it also eats up twice the amount of RAM wich is 
supercheap nowadays BTW. (EXS24 instrument 
editor/preferences/samplestorage/32 bit float)


Cheers,

Nick (with 2 gig's of RAM, repairing his Karma)

Sorry, voice 65 is stolen, but I don't know from where. My kurz 2500 is 
an intelligent thief, with only 48 voices he knows that bassnotes 
should not be stolen when there are decaying middle-range notes.. But I 
guess the EXS just picks whatever comes first..

Does one get the benefit of 32 bit float after samples have been imported
from, say, gig format? Or does the benefit only occur if the samples are
imported with 32 bit mode active?

As far as Gig conversion goes, all the conversion is doing is extracting the 16
bit wavs from the gig archive and storing them as 16 bit wavs on disk.
Gigasampler does not yet support 24 bit audio formats.

The 32 bit preference thing is merely a CPU saver.  All audio passing through
the audio engine is in 32 bit float format. So, if you have not activated 32
bit float setting in the EXS24 prefs,  the samples load into RAM in 16 or 24
bit format -- whatever they are in on hard-disk. 

Before each voice can be processed by the EXS24 it has to be converted on the
fly to 32 bit float -- this process consumes CPU cycles. If you activate the 32
bit setting in the prefs this conversion takes place during loading of the
instrument to RAM and you save on CPU when the instrument is playing.

This benefit is probably negated if you have disk steaming active as the
conversion of samples streaming up from the hard disk has to happen on the fly.
With streaming active only the initial attack of samples is stored in RAM --
the rest streams up from disk as needed. This might explain the limitation on
the sample start modulation (set it all the way up and you are still only a
little way into the sample) -- if it was otherwise the whole sample would need
to be in RAM for instant response.

Hi Murray,

I guess that you are referring to the older Gigasampler which is no longer 'in
production'.

Gigastudio, which has been shipping for a couple of years, supports 24 bit
audio...

That's correct.

An interesting tidbit is that it is possible (with Translator, on Win, so 
far) to create a .gig file that contains 24-bit waves. Giga can load it and 
it dithers it on the fly This means that at least you get to retain the 
information on the file.

But if you resave it in the Giga editor, the 16-bit dithered info gets 
written. This is also the case if you import 24-bit waves into the Giga 
Editor and save it.

How useful this is, I don't know, but at least it could be handy.

Nemesys has stated (at least Jan of last year) that 24-bit streaming on 
their patented system is really tough and perhaps not desirable as it would 
bog down the system too much. They were claiming that their new compression 
schemes solved that problem; however, this was pertaining to v3 and hasn't 
emerged yet.

So then, gentlemen (et les femmes, aussi),

One should, if one has the RAM resources, set the EXS-24 for 32 bit 
float, even if the samples were not imported as 32 bit float or 24 
bit fixed.

Thank You,
