Hi Bastl Instruments!

I'm trying to build the MG2 from scratch. I ordered all the parts and took your schematics and made my own PCB and assembled it, and I'm trying to now get the software working.

Of course there are a few hardware aspects that are a little different on my board, such as the RGB being common cathode instead of anode, and I successfully hacked the mg2HW class to get my LEDs, buttons, and display working nicely.

I've run into an issue with the waveRP library though. It seems that the most current version of waveRP has no way of getting the Sd2Card pointer from the SdBaseFile pointer that is passed to the WaveRP::play() and other methods. I've successfully initialized the SD card and the root directory, but when I hit a big button to play a sample the MG crashes and either reboots or doesn't respond.

Do you have any suggestions? I am willing to do some hacking in the WaveRP files if you can give me some direction, or maybe you can provide me with compatible SdFat library (the one that you guys use).

Thanks so much!
