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

I found that the DK80 responds to some undocumented sysex message ;) Try to send him the request F0 21 00 nn F7 (with nn standing for the patch number) and it will dump the corresponding patch data. I am still stduying the content of the dump...
Meanwhile the request F0 21 00 64 F7 seems to trigger a quite long message... maybe the sequencer data ?

It was mid 1984 the DX-7 was selling strong. I was a Salesman at Apex Music in San Diego. There was a concert at the Fox theatre up the street and the keyboardist for the band Black Uhuru came in looking for a deal on theDX-7. I demo'd the keyboard as Tom Piggot showed us to. The guy chose the DX-80 over the DX-7. (Actually the $1395.00 Price tag sold him over the DX priced at $1895.00.
Or was it that the Tom Piggot Demo worked again.)
The Bitimbric sounds are great!
I still own one of these in my personal collection as well as the DK-70 w/the remote grip!

The oscillators are DCOs not VCOs. In the 1980's there was a sound editor software for Commodore 64 for this synth. Great machine btw, I have one.

Actually, it does not have membrane buttons. The graphics on the left is just a legend that tells what parameter number to enter. All the editing is done with the numeric keypad on the right.

Yeah it's known as the Suzuki EX 80. It functions just like a Crumar Bit One with a two segment led display. The specs of the EX80 are the same as for the DK80.
