I built a test control panel out of an empty speaker box:

I went with the LED-Wiz+GP as my I/O controller. I figured that this would be efficient for my needs given that I only wanted to use a few buttons and the only force feedback devices I was going to use were LEDs. However, the initial keyboard input setup was riddled with problems. It took a full day of wiring, soldering, swapping around inputs, and configuring the keys to get everything working perfectly. And let me tell you, it wasn't easy... Well, setting it up for VP was a breeze. The problem was getting it to work with HP.
Ultimately, it took a combination of a couple methods to get everything running correctly. First I followed mameman23's advice:
tiny update for this week. glass is ordered, will be here next week. T moulding installed to other side of the head. standard buttons wired up.
currently sourcing shaker and solenoids this week.
Spent the day getting a ledwiz+gp working perfectly in both Hyperpin and VP. bit of a nightmare to start with but with some different key assignments its all working.
trick was as follows:
in hyperpins settings.ini I removed all the entries for the pinball wizard device, also removed the line in the keyboard settings for Genre (don't use it and was giving issue with the enter key). then mapped in the settings.ini file the UP and Down keys (left and right scroll in Hyperpin) to the left and right arrow keys (37,39).
the in Xpadder (free version), I mapped the left flipper button to both left shift and left arrow, and the right flipper to button to right shift and right arrow.
save all your settings and ini files, and working perfectly.
After doing this, it "kinda" worked correctly. However, I was still having issues with buttons executing multiple commands at once (even though they weren't programmed to in the config). For instance, the right flipper button was sometimes executing a table to start up as I was scrolling through the menu. The Launch Ball button was also triggering the flyer to pop up sometimes. Obviously, I couldn't be havin' that.
To get the config the rest of the way, I also followed some of granter's progress over at the HP forums:

So yea, it took a combination of tweaking XPadder and HP's Settings.ini, as well as swapping around the inputs on the LEDWIZ itself to get everything to work properly. For anybody reading this thread, I would suggest buying an ipac or keywiz for your button inputs and a regular ledwiz for your force feedback devices. Otherwise, be prepared for a lot of trial and error.
The LEDWIZ+GP is cool in concept, but its execution leaves a lot to be desired.
