Gemini Sound GPP-101 expandable wireless MIDI keyboard — 24 light-up keys, Bluetooth 5.0, magnetic expansion to 72 keys

A starter piano built for the way people actually learn today — wireless, app-connected, and small enough to throw in a backpack. Gemini Sound's GPP-101 pairs with your phone or tablet over Bluetooth, lights up the keys to show you what to play, and magnetically snaps together with more units when you're ready for a bigger range. It's the easiest way to go from "I've always wanted to learn" to actually playing. Key features Light-up keys show you what to play — Each key glows to guide your fingers through songs and lessons. Follow along in real time instead of squinting at sheet music you can't read yet. Snap on more keys as you grow — Magnetically attach a second or third unit to go from 24 keys to 48 or 72. Start simple, expand when you're ready for both hands and bigger pieces. Wireless and cable-free — Connect to your phone or tablet over Bluetooth and play through the POP Piano app or any MIDI-enabled music app. No dongles, no tangled cords, no setup headaches. Grab it and go — Slim, light, and built-in rechargeable battery. Practice on the couch, on the train, in your kid's bedroom — anywhere you've got your phone. Works with the apps you already want to use — Compatible with iOS and Android, and with any music app that accepts MIDI input. Charges over USB-C like everything else you own.
