Anyone know more about these? Looks like a scaled down version of the DS-310.Update via Qwave in the comments: "The DS310 was the digital additive synthesis add-on for the DS202 and DS101. I used to have the DS202 with the DS310.

The DS310 could only be screwed and connected on the left back of the DS202 and DS101 keyboards. The DS320 was always on the right side of the keyboards back panel.
The DS310 had the ability to create and store 4 (four( sounds. Each sound was made up from 3 different spectrums of 16 harmonics each. And these spectrums were crossfaded and overall envelopes by one of the 3 (or 4?) preset envelopes with variable time segments.
Because of the limited memory slots I wrote down the sound on paper too. I stil got some of the paper today. I also recreated two of my favourite Seiko sounds on the Waldorf WAVE's build in additive wave and wavetable generation pages.
The sound available through this additive synthesis were kind of a budged Synclavier to me then. You could do nice sounds unavailable be all synths under 10.000 US$ then (early eighties). But there was always one oscillator. So you needed to layer the sounds (available only on the DS202 keyboard if my memory is still right). Or use the DS202 build in single preset chorus for wider sounds. The low end was also very thin. So you usually ended up using extrem digital sounding things.
And yes, once you changed the spectra, the DS310 needed to calculate a second or two to make the new sound audible. No real time. But this was kind of stone age of digital synthesis in the years before the DX7.
I sold the Seiko to gain money to buy me a PPG wave 2.2 in 1987."

Fascinating. Thanks for the info Qwave.
ReplyDeleteLooking for a 13v 15w ac adapter for a DS-202.

Actually, the sequencer's model number is the DS-320, not the 302.

Thanks! :)
ReplyDeleteNeed a power transformer for my DS 202, or an adapter to convert the standard 12 v plug to the Seiko plug. It's a versatile instrument with the DS 310 module I have attached to it. I am also looking for a DS 320 module.
