speaking of an interface. "drool" is a crank operated drum sequencer that i am working on. this is the first working all-in-one prototype. i only have this crappy video demonstrating (to myself) the newly added <i>autoplay</i>. which is "without the crank". so the idea gets lost in the video.
the sound is generated with solenoids as well. the data is send via midi. i actually build a custom cajon for that installation, but the hardware part is still a big issue. i'm currently having one month "exhibition break" on that project.
