 (h1 [Wavedrum])

 (p [I wrote a ,(ref "/tags/wavedrum.html" "series of blog posts") in
     which I document my efforts to understand and possibly manipulate
     the firmware of Korg’s Wavedrum.  The PCB is easily accessible
     and exposes big connector pads as well as a microSD card—an
     invitation to play with the hardware.])

 (p [Although I’m perfectly content just playing with the hardware, I
     do hope that my work will eventually allow me and others to
     modify the data on the Wavedrum such that custom sounds and loops
     (and possibly algorithms) can be used.])


 (h2 [Current status])

 (p [It is possible to load firmware from the microSD card by pressing
     ,(em [Write]) and ,(em [1]) while powering on the Wavedrum,
     followed by pressing ,(em [Write]) again (another undocumented
     mode can be entered by pressing ,(em [Write]) and ,(em [Mode])
     while powering on).])

 (p [The Wavedrum unfortunately rejects any modified firmware.  The
     Oriental edition will not load the firmware of the Original/Black
     edition, nor will it load the firmware of the Global edition.  It
     also won’t load any modified firmware (e.g. where the only
     difference is that two bytes are swapped).  I intend to figure
     out how the Wavedrum validates the data on the SD card before
     deciding to reject them.])
