Hi!
PoKeys does support matrix keyboards (128 buttons), It can work as a keyboard emulator and/or as direct IOs for Mach.
Also new "PoNET kbd48CNC" keyboard with LEDs and light sensor will start selling in 1 week. We have a stock already. They must be programmed and tested before. Keyboard is watter and dustproof and has beautifull frame made from hard anodized aluminium. The keyboard is connected to PoKeys with 5 pin cable.

One by one.
Just do it it can be done

Yes, you need cap for each input.  Please connect them with shortest possible wires.

Can you please add a schematics how and what you connected to PoKeys?
For digital inputs there is no hardware debounce. There is a very cheap and easy way to get in order with hardware.
For example 100nF ceramic capacitor connected to between PoKeys input and GND could help a lot.

Hi!

More than 2 MPGs can be connected to PoKeys.
