Konkreet Labs put together this demo video of their Synth In A Book – a MeeBlip synthesizer built into a vintage hardcover book:
MeeBlip is being fed MIDI signals from Ableton Live and the audio out is then processed again by Live. Konkreet Performer is controlling the MIDI velocity as well as audio effects.
MeeBlip itself was a breeze to build, the book casing was a bit trickier and probably spent more money on different types of glue than on the MeeBlip itself.
Another device you probably don’t want to take on the plane, unless you like body cavity searches.
Build photos are available at the Konkreet Labs site.
