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 vastly underrated synth but you have to open it up if the resonance trim pots have not been altered as the factory setting has it far too low. It's pretty safe to tinker about with the pots but take a photo first so you know how they were set as you might mess up. (port P1 & then the 3rd one along to the right I think). Turn up the res to 15 & the freq in the middle, turn the P1 so it self oscillates & then pull it back just a touch. It is well worth doing as it really brings the synth to life and you really get the true sound of the SSM filters.

SEIL stands for " [beep] ty Italian ELectronics". I had 2 of these. (& a Siel MDP 40 Drum Machine aka Suzuki RMP-40) The 1st DK80 did not work at all. I took it back & got the 2nd DK80 which worked for all of 3 days before I returned that 1 too. My mom even called SEIL HQ in Italy. Anyway, I couldn't get my money back & ended up with a store credit which I used to buy an overpriced Casio HT-3000 ($900) It's my own fault for buying a keyboard at a small, unknown music store, from a guy named "Diamond Dave". (although to my credit, I was only 14yo) He was worse than any used car salesman.

Besides the DK80 there is also the EX80 or Siel Expander 80 or rebadged as Suzuki SX500. These are expander modules with half the voices of the DK. In the guts of these machines there are a SSM 2045 for VCF/VCA and a SSM 2031 for the HF VCO. In the DK there are 2 of both and in the expander module just 1 of both. A cheap way to get your hands on that famous SSM sound.

Got one, love it. It's my main workhorse. Got it linked to the MIDI boxes and to the recorder.
By the way michael, ever considered opening the thing up and cleaning the contacts? I did that. Takes a few hours to do, you need cotton swabs and cleaning alcohol. Hope that may help!
Now, go make music!! :)
