Activating a button with another's off command - MIDI Designer Q&A

You want one button, when turned off, to turn another button on? What about when turned on, should it turn the other one off?
Yes. I'm using a bass sound, I want to press a button and activate a program change that takes me into slap bass while I hold it. Then when I release the button it will re-activate the original bass sound. Sort of like a shift function. This all works with the supercontrols I have set up, except the part when I release the button I can't get it to shift back. Thanks.
Unfortunately, program change momentary buttons only send their "on" value. I'll have to cook up a solution for you, but the pieces are going to be a knob which sends the program change and a momentary supercontrol with the "force not stepper" set to on. I'll respond tomorrow with that, but if you figure it out first, more power to you.
sorry, I'm lagging on getting to this. Soon, thanks for your patience.

Hi and thanks for your question. Would it be okay if the control that sends the program changes is a knob instead of a button?
 
If that's okay, you have this setup:
 
Knob: it's a program change knob that has a min and max set to the two programs that you're interested in going to and from, respectively.
 
Button: it's a momentary button, supercontrol of the knob. It is set to "force not stepper." Otherwise it would step through the values of the knob on each press.
 
That's it. While the button is pressed, we're in program 2 (the max of the knob). Otherwise we're in program 1.
 
Note: For anything more complicated, the knob would need to be a supercontrol of buttons (which would become a button group).
 
Please let me know if this answers your question or if I've missed the point. Thanks!
