			Now you are ready to reprogram your Radel Nano Dx.
			Upload any compiled hex file as you would for any AVR controller. (see here: http://www.youtube.com/watch?v=YtTpUbnct6s&feature=relmfu)
			The chip is a AVR ATTINY 2314 (-20) and you do not need to program or change any fuses since they are already ok.

			Radel Electronics Pvt. Ltd. is the pioneer in the field of electronic musical instruments for Indian music. Radel started in a garage in 1979 and has today state-of-the-art facilities for designing and manufacturing a wide range of Digital Indian musical instruments. Time to hack one of their products I would say.<br>

			The hack is based on a careful reverse engineering of the devices main electronic board. The reverse engineering was pretty straight forward thanks to the careful design the Radel engineers made. Most components are SMD and labeled. Here the PCB and the schematic that goes with it:
