(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.])
