Nanoloop is the name of a sound editor created for the Nintendo Game Boy. The cartridge includes a sequencer, which can be fiddled with in real time, while the song is playing, and a wave form editor, in which you can build your own sounds. The current edition of Nanoloop, 1.2, is sold out, but version 2.0 is said to be available soon. Wonder what kind of music such a toy — er, tool — might produce? There’s a nearly four-minute demo (track here), which has the dutiful blips of a video game, its occasional modulations suggesting level changes. And with its echoes of contemporary glitch music, the extended fadeout owes more to Autechre than to Mario. More info at nanoloop.de.
