From c1988 came the legendary Yamaha PSS780 Music Station. It’s sort of a consumer DX7 with mini keys, a drum machine and rudimentary sequencing. You can edit the sounds which is cool. I got mine for 0, though it’s only partially functional and such can only be used as a MIDI tone generator which is a shame. Hope to get it fixed. Check out http://www.youtube.com/watch?v=TZ_yvI4gE0c

Follows from my 790 beats last year!

Sorry no tempos here, but range from about 60-180 bpm. Both bars of the pattern should be available for sampling. There are 99 patterns, with some repeated.
