I know some pedals do this and I'd love to have the same functionality on my Axo pedal. So I have two momentary footswitches (hardware wise) on my pedal. One of them is a faux bypass switch, the other makes it so whatever is in the delay buffer is stored/frozen/repeated indefinitely. For longer delay times/loops having this footswitch be latching makes sense, but I've also found that I quite enjoy freezing short samples to get a glitchy stuttery effect. But it would be neat if I could have that be momentary, like little bursts of samples. Some pedals, like the Pladask FORM2 solves this by you either being able to tap the switch for latching/unlatching or hold the switch for 500ish milliseconds for a momentary function. Is there any way to do this in the patcher?
Momentary AND latching footswitch?
Everything you describe can be done, for latching and unlatching, there is a generic object in the "Logic" section, (can't remember what its called, am away from my pc till much later today), it can turn a momentary switch into a latching one, this is the reason why all my foot switches are momentary, because you can choose. not only do I use an option to have latching or unlatching, but I have my signals invert-able as well. For example, you can start a trigger by taking your foot off as well. This is all quite simple to setup. I can't remember exactly, but I may have even posted the object.
As for the millisecond period, this can also be done, but is a little fiddly to get it the way you want, but very doable.
This is how I've been doing it using the logic/toggle as Gavin recommended
I've been using a mini 2 way toggle to switch between momentary and latching but you can set it up to a midi pad or whatever to trigger it. If you want to use another momentary footswitch to do the toggling, just add another logic/toggle between between that footswitch and the mux switch and it'll work the same
Thanks, but I don't want to add more toggles or switches. The pedal design is already done, I was just wondering if I can use objects to make the switch work as both a momentary and latching switch, so tap to latch and unlatch, or hold (for a few hundred milliseconds) for it to act as a momentary switch. If that's impossible, it's OK. Just thought I'd ask the OG masters. 
try this. Note that you have to decide how the momentary function should work when the toggle is on. Like now when the toggle is on momentary will keep it on and turn off once the button is released.
You might need some more logic patching if you want the momentary button to temporarily turn off the toggle.
OH HI.
Some of the other forum axodads were asking for this, so I patched up a solution:
Works great!
