auction details:
"SUIKO-ST50 is extremely rare and most strange japanese electronic musical instruments
it was originally made for japanese traditinal music circa. 1990.
SUIKO-ST50 was a expensive and most full functional product of SUIKO series

SUIKO-ST50 was very expensive and made very limited quantities those days
originaly made for the very small circle of the people who seriously studying japanese traditional music
and never sold at ordinary musical instruments market
so i'ts very hard to find even in Japan nowadays...
this is your first and last chance to get this vintage bizarre gem!

it has 2 rows of button keyboard
this keyboard specially designed for playing glissando easily like koto(japanese harp)
front row of the keyboard is japanese scale,so just playing randomly you can easily get exotic japanese melody!
it has internal stereo speakers and stereo output jack,phone jack,pedal jack,AC jack

there are various switchs for special japanese tuning, sustain,octave shift,vibrate,bend,mono/poly switch etc
trill switch easily simulates unique trill playing on Koto(japanese harp) two bend lever are available,pitch and sound level
most strange function is auto chord button(left below 4 button)
hold one keyboard and touch this button it automaticaly generates special exotic japanese style chord
it's not same as western theory but it from various japanese moods of poetic minds,really exotic!
and it also has auto play/rec function,you can record and play your performance
and play another instruments over your recording sound

many sounds are selectable,mainly japanese traditional instruments like shyakuhachi(japanese bamboo flute),koto(japanese harp) to oboe,strings,chorus etc..
in drums mode it become exotic rhythm section full of japanese traditional drums and percussion
so you can play all these percussion by tapping keyboard

sounds are very realistic,warm and strange!,unique original japanese sounds
even chorus or strings sound has dark vintage sound color like mellotron

I recommends SUIKO-ST50 for the artist who tired of western electronic instruments and seeking for fresh and bizzare sounds
and also recommends those who seriously studying japanese traditional music
