"The main voice is monophonic, with simple preset accompaniment rhythms (with 15 options for the rhythm's voice) controlled by the 'Gling' safe-note system. This heavily limits its potential as a solo instrument, not only because the beats are laughably thin but because the accompanying voices are fixed in their patterns.

There are 100 preset melody voices, mostly the standard Yamaha PortaSound two-op noises, but there's also a surprising amount of useable sound effects and slow, evolving (but moving in very obvious digital steps) pads. It's charming in its own incredibly lo-fi way.

The real area where it shines, though, is the step sequencer. It's visualized on an LCD screen in full stave notation with rock-steady tempo, adjustable to insane degrees! Notes can be edited in or out of the sequence at will. If this thing had MIDI out it would have become a cult classic."
