The KAWAI Q-80 is a digital sequencer with MIDI input/output and audio input/output, and was a famous machine highly favored by even professional musicians. I used to use it a long time ago, and I'm selling it to someone who is looking for one. I have confirmed song output from an external sound source via MIDI. The sound source in the photos is not included. Song save and load from FD is possible. Each switch is also working fine, but please understand that I have not confirmed all functions. I will include a third-party AC adapter and one check FD. - Brand: KAWAI - Model Name: Q-80 - Accessories: AC adapter, FD - Input/Output Terminals: MIDI in/out, Foot SW, Metronome, Tape Sync - Display: LCD display Thank you for looking.
