+# Wavedrum
+
+I wrote a [series of blog posts](/tags/wavedrum.html) 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.
+
+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.
+
+
+## Current status
+
+It is possible to load firmware from the microSD card by pressing
+*Write* and *1* while powering on the Wavedrum, followed by pressing
+*Write* again (another undocumented mode can be entered by pressing
+*Write* and *Mode* while powering on).
+
+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.
