Dunc's AlgoMusic
Dunc's AlgoMusic is a modest Windows homage to the Commodore Amiga program AlgoMusic. Music is generated from strings of text, either entered by the user, or pulled from a database within the software. Letter order is irrelevant, but case is. Instruments are defined by .WAV files, and can, presumably, be swapped-out. The software does not currently record the audio (it appears that no end point is created; music continues indefinitely) but the task could easily be done with a number of audio programs. The free Audacity, for example.

DuncanGEN
DuncanGEN is a modified version of Dunc's, which instead uses a sound library sampled from the Sega Mega Drive (YM2612)!
