keyboard velocity direct to filter cutoff

On the Sub 37, is the only way to have velocity affect the filter cutoff via the envelope VEL AMT? Is there no way to do it directly?

Thanks.

When the KNOB SHIFT button is blinking you can use the FILTER SUSTAIN knob (now FILTER
VELOCITY AMOUNT) to make your sounds get darker as you press the keys slower on the keyboard,

Page 32 of the Manual says DECAY but it really is SUSTAIN.

Thanks.
That's actually what I'm doing according to the instructions here....

I was just wondering if there was a more direct way to route it.

Hi aldred,

Quite often you'll find that there's some way to do something on a Sub 37.

Traditionally, having Velocity modulate Filter EG AMT is the most "musical" way of doing it. Why? Because, if you're using a Filter EG to create a dynamic timbre that goes from a desired brightness down to either silence or a specific darkness, you usually don't want the endpoint (FILTER EG SUSTAIN Level) to change based on Velocity. Typically, you only want the earlier parts of the sound to get brighter as the Velocity increases... and then, eventually end up at the same desired darkness regardless of the Velocity.

Multiplying VEL AMT x EG AMT is a great way to achieve this when the SUSTAIN knob is at, or close to, zero. Why? Because any Velocity multiplied by zero is still zero, so, no change.

But... that's not what you want. So...

Set MOD 1 or MOD 2's MOD SOURCE knob to PGM. Press the CONTROLLER button to highlight it and use the Up/Dwn arrows to get to the MOD 1 EDIT (or MOD 2 EDIT) line. Press CURSOR.

You're now in the MOD BUS (1 or 2) EDITOR.

USE the Up/Dwn arrows to get to PGM SOURCE and scroll to VELOCITY. (It's the 2nd-to-last of a long list of choices.)

Now, the FILTER AMT knob in MOD (1 or 2) will allow VELOCITY to increase or decrease (CW or CCW) the Filter Cutoff, independent of the FILTER EG/FILTER EG AMT/VEL AMT settings.

Thanks!
I had to set the PGM DST to F EG AMT for it to work. That's the right thing to do, isn't it?

And one more question if you don't mind. Why is it that the FILTER AMT knob is attenuating the effect by default? I couldn't find anywhere to specify it in MOD EDIT.
Am I missing something?

Thanks.
