Joe Mansfield's forthcoming book Beat Box: A Drum Machine Obsession has been on a few sites this week. This pic was on The Wire's website. It makes me feel a lot better about owning five drum machines!
The Maestro Rhythm N Sound for Guitar G2 shown here featured on the Beastie Boys' underrated Check Your Head album and I wonder if it inspired the track below.
PS -- Really like this idea of retrofitting MIDI. It's beyond me but tickles my recent obsession with circuit bent gear. Cheers Techdef!
