You'll be notified about news and stock updates for this project.

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 5 octaves. The twelve keys and the ability to switch up and down through octaves makes it easy to control an entire keyboard pianos worth of notes with our compact controller, which is about the size of a hamster. Hamster Mix connects to Mac, PC, Ipad, and even mobile phones through Bluetooth. You can control any MIDI enabled music program such as 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, meaning no wires and no bulky equipment.

Documentation & Support

Manufacturing Plan

We are assembling, testing, and packaging every " " to ensure quality and consistency. We’ve already manufactured and shipped X units to beta testers, which allowed us to fine tune our production process. We are also assembling all PCBs in-house to ensure consistency.

Fulfillment & Logistics

After our production run is complete, we will box everything up and send it along to Crowd Supply’s fulfillment partner, Mouser Electronics, who will distribute products to backers worldwide. You can learn more about Crowd Supply’s fulfillment service under Ordering, Paying, and Shipping in their guide.

Risks & Challenges

We are all aware of the global parts shortage that is affecting nearly all electronics projects these days. While we’ve already stocked most of the PCB components and other hardware we will need for the first batch of " ", there is still a small chance that production could be delayed. In the unlikely event that happens, we will keep you all informed through our campaign updates.
