EXS 24 Logic Sampler Users Group

Using Logic Pro 6.4.1 and EXSmkII, is there a way to assign a sample 
to a root key that will automatically loop the sample over and over 
after a single key(note) push? My very limited experience has found 
that in order for a loop to play, I have to hold the key down or 
repeatedly push the key in time with a beat. I would like the loop to 
repeat after one push and then use the other keys(samples) to play 
over that loop. This is probably a real simple yes or no, but I 
assure you I have thoroughly read the EXSII manual that came with 
Logic Pro and have not found this feature covered. 

Thanks

No, it's not.  And yes, it can be done.  But no, not in the EXS itself.

Enough yes and no's? :-)

The way to do this is by setting the sample to loop in the EXS 
Instrument Editor.  Then create an environment patch that filters out 
note-offs, so that only the note-on reaches the EXS, creating a 
'hanging note'.  And then you have to think of a way to switch the 
note off again.  This could be "switch off as soon as a note-on on 
the same channel is received" (like a monophonic synth), or "switch 
off as soon as the same note on is received again" (making the note 
work like a toggle).
The 1st part is easy: use a transformer to convert notes to 
controllers, use a 2nd transformer to filter out controllers with 
value=0, and then convert controllers to notes again with a 3rd 
transformer.
The other part -- a mechanism that allows you to switch off the 
hanging note again -- is trickier, since it requires you to store the 
note-number of the currently sounding note.  This can be done with 
e.g. a fader that assumes the value of the last played note.

I hesitate going into too much detail, as it is my experience that 9 
out of 10 times when I start writing stuff like this, people respond 
like "oh... yeah.. sounds cool, but... uhm... I don't really 
understand what you're talking about at all" :-).

Thanks for the reply Hendrik, but you said it best yourself, it's way 
too much trouble. This is the only way? I'm better off looping a 
region and using a long audio file as the sample, right?

Well... that depends...  If you want the ability to switch between 
different loops -- i.e. hit C once, have the loop play indefinitely, 
hit D which stops the previous loop and starts another one, etc -- 
then the environment solution would be worth it.
