Programming tip from John Lehmkuhl

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: --------------------- Message: 13 Date: Tue, 19 Nov 2002 13:35:26 -0800

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
