We have worked hard to make Freedrum extremely lightweight and precise. Freedrum uses the new Bluetooth MIDI standard which provides very low latency and makes it compatible with most iOS and macOS music software. Windows 10 support has recently arrived with the Anniversary Update.
Freedrum is powered by a tiny, high-capacity LiPo-battery, which can be fully charged in just under an hour, while providing enough power to keep Freedrum running for seven hours of constant drumming.
Inside the enclosure there's a PCB with a gyroscope that detects movements and interprets them as hits on a drum. Together with the detected force and a few other magic parameters it is then translated into MIDI. The MIDI signal is sent via Bluetooth to the connected app (e.g. Garageband on an iPhone) which then plays the actual sound via headphones or onboard speakers.
