I built this box, and it's sort of working, except I have an issue: tempo isn't registering correctly when using it to tap tempo for my Eventide Time Factor.
It sometimes sets tempo to 500bpm, and most of the time tempo is quite off.
By comparison setting up an IA button on the GCP (set to momentary) works flawlessly and very accurately, so I figure it's not related to the TF itself.
Might it be related to the switch I'm using on the tap tempo box ? I bought this one:

Thanks in advance, I'm pretty much stuck here !
Because the port you are using on the Ground Control Pro is intended for an expression pedal, it will not correctly read a momentary switch... actually, it is reading it "too correctly"
When you press the switch, the contacts bounce against each other. The Ground Control Pro is reading this bounce and interpreting it as movement between the endpoints. Neither the TimeFactor or the Expression Pedal port on the Ground Control Pro have data filtering to prevent this unwanted data from false triggering a Tap. The next Ground Control Pro software update will include the necessary filtering to use a momentary switch in the Expression Pedal Port, but for the now you will have to use an Instant Access button for controlling the tempo on the Time Factor.
I hope that helps!
p.s. I see you asked about the switch type earlier, sorry to have missed that
