EXS 24 Logic Sampler Users Group

I am running Logic 6.1, MAC OS 9.2.2, 768 RAM and Protools HD 2 
system. I seem to be maxed out at 15 EXS instances.  Any way to 
increase these?

Sorry for being sloppy and just pasting the whole thread below, but 
there's some confusion here and I want to straighten it out.

First, Logic has 64 Audio Instruments available, and you can put 
ESX24s on all of them (on DTDM auxes) *in addition to* the ones on 
DAE tracks. Usually Audio Instrument #64 is used by the Klopfgeist.

The main difference between putting EXS24s on a TDM object and a DTDM 
object is just that the former can be recorded directly to disk 
without using up your eight ESB inputs into the TDM mixer. This comes 
at the expense of being able to Freeze the track. (Someone correct me 
if I'm wrong, but I haven't found a way to Freeze on TDM objects.)

The other difference between TDM and DTDM EXS24s is that you also 
have fewer channels when you use TDM objects. I believe the limit is 
16 stereo channels of this DirectConnect stuff, i.e. I have 12 stereo 
EXSs and four stereo ESBs on TDM objects; if I remove two ESBs I can 
set up two additional EXS24s. This would have to do with the number 
of Auxes allowed. Someone correct me if I'm wrong here as well.

My Autoload has 63 + 12 stereo EXS24s set up, and only one 
DirectConnect chip is being used. That's in addition to the two chips 
being used already: one for the Mix Engine and one for the 
StereoMixer24. What's more, deleting all the TDM EXS24s has no effect 
the TDM chips. So I don't think it's accurate to say that this is 
DSP-intensive, since it takes up one DirectConnect chip either way.

Also note that you're likely to run into memory, disk performance, 
and voice count limitations before filling up all these EXSs. But 
they are available, and it doesn't cost anything to have them set up 
and ready to load with samples.

Finally, something's wrong if John's getting errors. I wonder if it 
isn't just the amount of memory assigned to Logic. EXS24s use memory 
not assigned to Logic, but Logic probably needs memory to set up all 
those instruments.

Thanks for straightening this out. I don't actually have a TDM system. 
But I have done some work recently for a client setting up his EXS 24 , 
the DTDM environment, and ESB plugin; so it was somewhat fresh in my 
mind at the time. At least the basics of it anyway :-)

Good to know. I thought you needed a special TDM version of the EXS in 
order to run them directly on DAE tracks.

This seems to make sense.

Good to know. I knew the actual ESB/Direct Connect plugins were pretty 
DSP hungry. But I didn't know what kind of DSP was involved in running 
EXS's straight in your DAE/TDM mixer. Good to know it doesn't take up 
any extra DSP. I'll advise my client on this new found information.

You can instanciate an EXS24 on either a DTDM instrument or a DAE AUX, so
you have the best of both worlds and total freedom when it comes to EXS
processing.
