I used this to generate the "random" stuff on the FDS noise. It is a Visual Basic.net program so make sure you have the framework installed. If you click on either of the buttons it creates a list of numbers and copies them into the clipboard so you can paste into FT's FDS instrument definitions.
The 10min songs were generally all done with Mex so it was kind of a "competition" but not really.
Noise notes was set up by me setting the hz really high, then making different volume envelopes for the noise, then writing music around those pitches.
