"apparently in the early days of digital synths a unknown organ company developed the technology that is now in the seiko ds-250. in the early 80's the original designer asked for a price too insane for the market to handle and it failed miserably, that's when seiko licensed the technology and synthesis methods and failed with it's production of this keyboard.
it reminds me of old organs i've used like the conn electric band sans spring reverb or the moog organ sans filter except the seiko is bi-timbral. it has some basic preset sounds selectable for each timbre which define timbre and attack while there are simple controls on each voice for volume, decay, modulation slider with a on/off switch for a delay into the lfo cycle. you can detune the voices up to 14 percent and you can assign each note of polyphony a few selectable intervals. a chorus reminescent of the old junos. single voice mode, bitimbral mode or split point voices. key transposable, volume controls, pitch wheel, on/off buttons and a nice layout with simple but nice led displays.no memory but it's simple to setup. midi in/out./thru. midi seems primitive as i could really only get note on/off to respond although there is a way to recieve each voice over midi by a 16 way rotary switch by each voice. supposedly you can control detune via midi CC although this is from word of mouth. 1 voice per 2 output on 1/4" also on the side panel is alternate summed mono output, headphone jack, pitch fine tune, stereo rca outputs. input to footswitch sustain (works as sustain on/off rather than hold) input for trs expresion pedal for volume.
the video below is a short demonstration of the actual unit.. you will find a few other very rare mp3's online as well but i am not going to seek permision to repost here.. just do a search."
