I am working on a 4 player CP that will also have dual SNK Rotary Joysticks. I'm sure I can share inputs to keep my count below what an Ipac4 can handle but I will need to either buy Druin's Rotary Interface or an MK64 to use my rotaries.
If I use the MK64 that means I could avoid sharing altogether and still have a plethora of extra inputs for whatever junk I feel like adding (and BYOAC gets $5). And how complicated would it be to have both the Ipac and MK64 installed together?
If I use Druin's, the CP may be easier to program? And I can also add a switch(s) to change to the Frontline circuit shown on Druin's webpage to add another capability to my panel (I think).

Has anyone tried the MK with an Ipac?
I'm leaning toward Druin's due to price, ease and hoping that the Frontline circuit works.
I never saw Druin's FrontLine circuit before. Pretty impressive.
I don't understand what you are asking? Why would you need an I-PAC/4 and an MK64 - That would be 108 inputs? 64-12 for the rotary inputs + 56). I think it would work (if a keyboard had 108 key to define), using either the I-PAC/4 in USB or one controller daisy-chained to the Keyboard pass-thru.
Druin's interface will work with the I-PAC/4 without the MK64.
Did you mean to use Druin's interface with the MK64 (and no I-PAC?) That should work, but I would use the MK64 normally (like an I-PAC) and then wire the SNK's to Druin's circuit. This means you would only have 60 inputs b/c Druin's uses two inputs per joystick.
Only drawback is Druin's interface (I think) still requires +5V, but you could get this from the computer, or if you E-mail Ron, I think he will set up one of the MK64 input pins to supply a +5V output.
