It's time to relive the futuristic electronic disco sounds of the '70s, '80s and '90s with GIO-1, new firmware for the M-VAVE FM-1. It is generative: it writes music in these styles as it plays. Pick a song, play along on the keys and let the lead answer you, drop in effects, and nudge it in the direction your feelings take you. Feel love and enjoy!

What plays

• Bass. An analog-style sequence out in front: two saws and a square through a four-pole ladder (or an FM voice), short decays, the dry note on one side and its echo on the other. Seven pattern shapes, written in chord degrees so they follow the changes.
• Pad. Strings, a choir or detuned saws on the chord, voice-led, through a slow stereo phaser.
• Lead. Ten voices, from Mini and Odyssey to Theremin, FM Brass and Robot. It writes its own phrases. Play the white keys and it follows your line, answers it, and makes it the song's theme.
• Drums. Four on the floor, claps on two and four, open hats off the beat, and syndrum fills.
• The form. Each song is a set of sections with their own chord changes. It loops for ever, repeating, skipping, dropping a layer, or moving the whole song up a key for a while. Sixteen drop-in effects are under your fingers.
