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. + + +## Blog posts + +- [Disassembling the Wavedrum firmware](/posts/2014-09-18-wavedrum-firmware-disassembler.html) +- [Connectors on the Wavedrum's circuit board](/posts/2013-12-09-wavedrum-connectors.html) +- [Firmware comparison between Wavedrums Original, Black and Oriental](/posts/2013-10-31-wavedrum-data-comparison.html) +- [Hacking the Wavedrum](/posts/2013-08-11-hacking-the-wavedrum.html) + + +## Software + +[wavedrum-lib](http://git.elephly.net/wavedrum/wavedrum-lib.git) + +: Haskell library for parsing, editing, and writing Wavedrum + programmes (presets). + +[sharc-disassembler](http://git.elephly.net/wavedrum/sharc-disassembler.git) + +: Very rudimentary, partial disassembler for SHARC ADSP binaries + helping me to understand the Wavedrum's bootloader. -- cgit v1.2.3
