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

They're rare, cheap and usually worth it, just don't expect this to compete with a Matrix, Prophet, or even with a JX3p or Sixtrak - a Poly800 is about in the same league, but does sound different. The expander is monotimbral instead of bi-timbric. Keep an eye out for the Suzuki SX500 expander, which is exactly the same machine.

Don't expect a nice PWM wave from this, it just can't do that. Also, the envelopes are sluggish, there's no osc sync or other fancey mod stuff and the chorus... well, it's not a Dimension C!
Still: nice bass, good for typical eighties electric piano sounds (if you can live with no velocity sensitivity), strings & pads and a (one!) nice squelchy paraphonic SSM filter. Two LFO's are fun to play around with. Do get the memory card, since 10 free user memories won't bring you far.

A quirky synth with typical Siel idiosyncracies. Unfortunately, the above story doesn't tell half of it. Great about this synth is the midi functionality, meaning you can edit almost all parameters 'live' from a midi controller and record the whole bunch in your sequencer as long as you do not freak the underpowered internal processor out. It has limited waveforms, more organ like and comparable to the Poly800. Don't expect a nice PWM wave from this, it just can't do that.

just one of those underrated pieces of gear, partly because there's almost no decent demos online showing how smooth these can sound. Decent synth.

A lot of people talking out of theit a** about this synth. Is it "fat" and the other cliches ? No. Does it sound sweeter than a lot of DCO synths ? Yes.
