We all know that some of the best synths now run on computers, but Fridgebuzzz's Atari Synth is the first we've seen to be actually built into a piece of computer hardware.
Based on the case of an Atari 400 console, though the innards are all new, this is a 12-oscillator, three-modulator square wave synth.
Triggering of the 12 oscillators comes via the arcade-style pushbuttons (you can also activate a 'drone' mode), while the sound can be tweaked using the knobs on the top.
Audio output and power sockets are round the back, where you'll also find a volume control.
If you fancy buying the Atari Synth, we're afraid you're out of luck – it's already been sold – but Fridgebuzzz does say that it's working on a handheld version.
