It is a rhythm box analog pads (cymbal, snare, kick, two toms) and presets. There are 12 presets, you can combine them to make more complex rhythms. To change the sounds, there is a knob to tune, the volume knobs for the cymbals / hi-hats and kick, and that's it!
There is also a knob for tempo, bpm, but are not shown.

UTILIZATION

Use could not be more simple. You can type the pads or trigger presets, or both at the same time.

SOUNDS

The sounds are not at all ralistes (requires analog), but I find them really do mal.Elle trs electronic sounds.
The snare is snappy, it looks a bit like that of the TR606. The cymbals are not bad, although sharp. But the best sound is really the kick: when you put the volume back kick, a kick really gives a solid, widely used for techno or house.
Otherwise, the toms are not bad for such old toms make electronic drum, toms sounds like we can agree on some disco songs.

OVERALL OPINION

I use it recently prs 3 years. It is a rhythm box rev limit (for non-programmable), but the sounds have a color I find quite particulire and truly original. If you want to give a touch of your analog rhythmic idalie it is for a, especially given its price (I paid under 100 euros).
It is clear that as the only box rhythms limit but it really sounds good to throw some old school electro, it serves well.
Exprience I would do with that choice.
