William Sun Petrus took an old 1920s Remington Portable typewriter and modded it into an electronic drum machine. Basically, it works as a MIDI controller, so it can play whatever sounds he loads into Ableton. He had to remix the live audio so you could hear it over the mechanical clacking sounds though.
Awesome Drum Machines
Roland’s latest electronic rhythm maker, the TR-6S packs a six-track sequencer into a portable, battery-powered box. What really makes it special is its ability to play sounds from famous drum machines like the 808, 909, 707, 606, along with preset and custom samples, as well as FM-generated tones.
Korg’s portable drum machine is packed with 60 patterns and 120 fills, and has 16 Velocity-sensitive performance pads for editing your own patterns. It can run on AA batteries or AC power, has a built-in 2-watt speaker for practice sessions, and a 1/8″ stereo output and footswitch inputs for live performances.
