I noticed something about the way S1 implements keyswitches.

This is what a guitar part looks like to start with:



Just a few short keyswitches.

Sounds like this:

But if I setup the keyswitches it looks like this:



This make the keyswitches sound until the next switch.
Hear the difference:

I found I could make a new keyswitch called Stop that calls an unused key like C-1:


After doing that it sounds like the first one, back like it should sound.

Nice if there was a way to switch that behavior on and off.
