EXS 24 Logic Sampler Users Group

Hi All,

For those of you who may have missed it on the LUG yesterday, John Lehmkuhl posted a nice little step by step tutorial on setting filter cutoff and key tracking parameters to be effected by velocity to get more playable instruments. I found it quite useful and thought I'd pass it along. Here it is:

To make this simple I figured I'd do this "tutorial" with a pre-existing
program to start.  Follow the steps below:

 From the EXS factory folder, load up "Stereo Grand ECO".
 From my Korg Triton keyboard, this is not very dynamic, even though the
filter is turned on.
 To give the filter more range lets do 2 things. First, bring down the
filter cutoff (big know top middle of screen that says "Cutoff" above it). I
wanted to make this a much darker piano since it's not very pretty when it's
bright. So I moved the cutoff knob from it's 11:30 position to about 9:00.
That made it nice and dark, but almost too dark. I want it so that if I dig
in with velocity, that it will get brighter. To the right of the filter knob
You see the "ADSR" slider. Actually, you see 2 halves, the top half is the
"Top" of your velocity range and the Bottom half sets how dark the sound
will be with a velocity value of 1. Take that top half of the circle and
raise it up - I have it at about 70%. Again this is VERY subjective based on
what keyboard controller you use (the Nord Lead plays WAY to sensitively
with the above setting compared to the Triton's velocity curve).

Now that the sound is very dark when you play soft, it might be too dark in
the lower range of the keyboard. That's what the "Key" knob is for. With
it's current setting, it is filtering the bottom of the keyboard range too
much so bring it down to about 9:00 and notice how the bottom range of the
keyboard is brighter now  - much better.

 It gets too dark sounding too quickly. That is because the Env 1 "D" value
is too short. Crank that slider up to about 90-95% and play the top register
really hard to hear the filter action.

 Finally, to make it even more expressive you could have the Amp respond
more to velocity. It's not very dynamic in its' default setting. So, Grab
the lower half of the slider called "Level" and bring that down to 30% (it's
currently at about 60%) and notice how the sound is now even more softer
when you play softly.

Viola !!

Now you can play solo piano with the "Stereo Grand ECO" patch where you
couldn't before.


Hope this "helps" ==)
EXS can do so much more, but lets start with this.

Sincerely,
John Lehmkuhl
