Hamster Mix is a portable MIDI controller powered by Arduino that connects via MIDI over Bluetooth. It allows you to control effects as well as play MIDI notes within five octaves. The twelve keys and the ability to switch up and down through octaves makes it easy to control an entire piano’s worth of notes with a compact controller, which is about the size of a hamster. Hamster Mix connects over Bluetooth to Macs, PCs, iPads, and even mobile phones. You can use it to control any MIDI-enabled music program, including Ableton, Garage Band, FL Studio, Reaper, and more. Two additional buttons and two potentiometers allow you to set your own custom effects. You can even use the buttons as a Bluetooth track launcher instead of as a keyboard.
You can also control phone apps with MIDI support such as GarageBand, FL Studio Mobile, Reason Compact, Audiokit Synth One, Moog apps, and more. Use Hamster Mix to make music on the go with a device that fits in your pocket and requires no wires or bulky equipment.
