This is the DONNER N-25 compact MIDI keyboard. I used it as a sub-keyboard for DTM, iPad, and laptops. It's USB-C powered and can be connected directly to a PC, Mac, or iPad. Despite having 25 keys, it has basic functions like octave switching, transpose, sustain, and program change. It's lightweight and doesn't take up much space, making it suitable for portability and space-saving environments.
