Seiko DS202 1980’s Digital Synthesizer Keyboard with Sequencer & Synth Modules, Power Supply
I bought this synth used in 2012, and at best it was capable of its basic keyboard functions, but it always had a surprise glitch and would have to be powered down and restarted. I’m in a selling mode now, so I had an electronic technician give it the once-over this month. It was occasionally capable of providing its keyboard programs and rhythms and its chorus, vibrato, sustain and auto bass functions and speakers worked well. However, sometimes simply touching the keyboard would drive it into loud microphonic static noise, and the C5 key wouldn’t produce a sound. We tried cleaning the contact strip to address the silent note, and wound up with 10 keys that wouldn’t sound - C3, C#3, D3, D#3, F#3, G3, C4, F#4, C5 and F#5. At that point we decided to button it back up and put it up for sale. Included are the DS-202, DS-310 digital synth, DS-320 Sequencer and Seiko power supply. The two keys that have been super glued back together are sturdy.
As you can see in the first image the keyboard and both modules light up, but the modules are untested. For what it’s worth, I have an office where someone who is interested in buying it will be able to listen to it through an amp. $495, trades considered.
