Some folks bring out an heirloom table runner when they have company, but what if you sewed your own and made it musical? We'd never put it away! [kAi CHENG] has an Instructable about how to recreate his melodic material, and there is a link to his website, which describes his design process, not just the finished product. We have a video below showing a jam session where he exercises a basic function set.
GarageBand is his DAW of choice, which receives translated MIDI from a Lilypad. If you don't have a Lilypad, any Arduino based on the ATmega328P chip should work seamlessly. Testing shows that conductive threads in the soft circuit results in an occasional short circuit, but copper tape makes a good conductor at the intersections. Wide metallic strips make for tolerant landing pads beneath modular potentiometers fitted with inviting foam knobs. Each twist controls a loop in GarageBand, and there is a pressure-sensitive pad to change the soundset. Of course, since this is all over MIDI, you can customize to your heart's content.
MIDI drums come in all shapes and sizes, from a familiar game controller to hand rakes.
