Yamaha QX-1 Digital Sequencer Recorder

The QX1 was the first MIDI sequencer by Yamaha: clearly aimed at studios with its high price and its MIDI capabilities back at a time when very few synthesizers had digital connections.

It features a built-in 5.25" floppy disk for data storage and 8 independent track with 8 separate MIDI OUT terminals.

Recording can be carried out in real-time or step-write modes, with enormous overdubbing capacity. The QX1 permits highly detailed editing and manipulation of all recorded data.
