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
