Steve Cooley designed a pretty deluxe hardware interface for controlling music software, better known as the Beatseqr. Since it’s based on an Arduino Mega, the device can of course be reprogrammed to make use of onboard faders and LED buttons in a variety of ways. Beatseqr sends data out in the form hi-res OSC messages, which can be converted in software down to MIDI. Source code for the project is available on github and prebuilt versions of the hardware are now for sale on Maker’s Market.
