ซอฟต์แวร์ synth สำหรับคีย์บอร์ด USB Midi
Plug in a USB Midi keyboard and play it. No settings, no distractions.
Supports legacy devices that the Marshmallow Midi API doesn't. All the heavy lifting is done by two great libraries, https://github.com/kshoji/USB-MIDI-Driver for communication with the device and https://github.com/billthefarmer/mididriver for sound generation.
