At first I tried debouncing the switch, didn't go well for me
It's basically a fixed expression pedal with no pot.
Here's the clip:

Here's the wiring diagram:
Mess around with the resistors, start with R1 = R2 and then decrease or increase the R1 value until it gives you CC Value 64.
You do have to measure the resistor values.
** CC value 64 works for me, it might not work for your gear. **
*** If you have another expression pedal that you wanna use, be sure to plug it in to an EXP port.
It affects the CC value of the other port somehow. ***
I end up with R1=9.33 kOhm and R2=9.75 kOhm.
Theoretically, if R2=9.75 kOhm then I think R1 should be around 9.45 kOhm but this is the closest I have.
This works fine sending MIDI CC to my Atomic Amplifire (tap tempo, turning things on/off).
No switch bounce problem at all.
