Basically if you need the short version, find the ones that look like this: OwnHammer-Impulse-Responses\OwnHammer-Public-Beta-Redux\Wav\44100-Hz_Stereo\OwnHammer_412_PBR-BOG-ST_V30-CH_57_USA-Modern-2.wav
Rename it to this: 001 OwnHammer_412_PBR-BOG-ST_V30-CH_57_USA-Modern-2.wav
Put the SDCard in yout PC and copy that into the EPDA folder (might want to back up what's on it first to your hard drive in case you need it and back up your card once in a while just in case so you always have your favrites on there)
You MAY have to visit the website if the cabinet firmware is not loaded and get that file. Here's the firmware page with downloads and instructions: http://www.logidy.com/?pid=9
One thing that was awkward for me at first was that even after you finally get it working, when you change IRs, you have to tap the [Recall] button because I think it writes that IR to memory (plus side is that will work from then on even without an SDCard, but to me is just an anoyance). I'm guessing though that if you have the footswitch, you wont have to deal with that?
This is a great little box, I'm glad that made it in stereo, that adds a lot of possibiliies. I find that the stereo ones sound better to me, even if you decide to record to mono tracks or convert them to mono tracks.
