Hamster Mix Bluetooth Arduino open source midi piano
“Hamster Mix connects to Mac, Pc, and even mobile phones through Bluetooth. You can control any midi enabled music program such as Ableton, FL Studio, Reaper, and more. 2 additional buttons and 2 rotary controllers allow you to set custom effects. You can even use the keys as a Bluetooth track launcher instead of as a piano. You can control phone apps with MIDI support such as Ableton, Fl Studio, Korg’s iPolysix, and more. Use Hamster Mix to make music on the go with a device that fits in your pocket, meaning no wires and no bulky equipment.”
