There is now a portable, silent, and easier way to play the drums on the go with Freedrum. It's a set of four sensors to realistically emulate a 12-piece drum kit. With a companion app, you can set up and personalize your drum kit over 10 zones. You can use it with other software. Freedrum works with MIDI over Bluetooth. Attach the sensors to your drum sticks and feet and you’re ready to rock. With a rechargeable battery, you'll get to play the drums up to 14 hours.
