QX3Digital Sequence Recorder / 1987
This MIDI sequencer equipped with a 512 kB memory is capable of recording and playing back up to 48,000 notes’ worth of data.
The resolution is 96 pulses per quarter note. Featuring a built-in 3.5-inch floppy drive, the QX3 was essential for live performances at the time because
it was capable of storing and reading data on general media and suffered fewer problems than computers, such as freezing.
