"Really wanted something OP-1 sized but more performance focused (and cheaper), so i made it myself. It runs on AMY, i've currently added the built-in patches and implemented a BLE MIDI keyboard mode, later will start adding my own instruments.

Originally planned to use korg nanokey2 as the keybed, but the feel was so bad that i had to switch to low-profile mechanical key switches.

Overall extremely happy with the result, especially given that it's my first big electronics project"
