- 12 OBS preset rhythms {rock, disco, 16 beat, swing 2 beat, swing 4 beat, samba, bossa nova, beguine, tango, march, slow rock, waltz} with piano(?) accompaniment
- rhythm fill-in
- main & accompaniment (with rhythm) volume sliders
- tempo +/- buttons (20 steps)
- semi- analogue monophonic sound generator similar like VL-1; the digital envelopes (with audible zipper noise) are linear and thus sounds unrealistic because they fade silent too soon.
- chord sound with fixed timbre (3..4 voice squarewave organ)
- simple analogue percussion with transistor noise (base, low tom, mid tom, high tom, snare, open & closed hihat}
- CPU= "NEC D1868G 007, 8441XK, Japan" (80 pins SMD)
