Some sounds from the mighty MB6582 (8x8580). Warning, not all of them are traditional leads or arps.
collage from old patches I recorderd:
No effects expect occasional cutting/looping, reverse and pitch shift from DAW.
Even older sounds: http://soundcloud.com/enth/sets/some-random
5 tracks, testing and testing2 uses shitty digital guitar effect pedal and some sounds are from preset bank.
Got 4 and a half banks full of weird patches, might record more later if I bother. And I’ll share some of the actual patches once I get to cleaning and indexing them… There’s even a topic for it but seems pretty empty atm
