Siel DK80

Siel DK80 Image

The Siel DK-80 is an odd synth that could be said to bridge the gap between low end mid-eighties Roland and Sequential type synthesizers. It is an analog synth with digital control. It is also bi-timbral with a split keyboard mode giving you 2 polysynths in one keyboard! The sounds are OK, and the DK-80 makes a great backup synth. It has an on-board two-track sequencer, chord memory and hold, programmable stereo panning and sweeping. Parameters are edited one at a time and via membrane push buttons. For a fair price the DK-80 is certainly an exotic addition to any synth set up but may be too limited to use as your main or only analog synth. It is used by Eat Static

A "no reason to buy" Synth. Sad !!
It is better than nothing of course.

There are many analogs out there, better search for them...

Very nice sounding little thing. It's the SSM filters that do it.

The laziness of the owner of this site amazes me, the more I look at this page the more errors I see. THERE IS NO STEREO PANNING OR SWEEPING - one osc is panned left the other to the right using chorus spreads some sound to the other speaker but that is the only control of the stereo field that I know of. Did the reviewer even bother to flick through the manual. "Sounds are OK" LOL they are cr@p until you alter the resonance on both osc and get them in tune etc.

The above is NOT a review read it is pure guess work from photos LOL

When I say filters below it's like the Korg Poly800 but with 1 for each Osc, also each osc has either saw at 4' 8' or 16' or differing levels of sqr at 2' 4' 8' & 16' but NO triangle or sine. The person writing the above review must only have seen photo's and took a guess.

As "Rich" said earlier (but can't tell left from right) The chart on the right looks like a membrane but is just a guide for the numeric & other buttons on the left. No editor needed as it's simple & quick to edit. Live edits can be done using CC & System excl as mentioned by Midimetric on earlier page.
