“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.”
