Siel DK600 Synthesizer w/ Preliminary Dot Matrix Printed Manual

Note: Auction links are affiliate links for which the site may be compensated.

via this listing

"If your looking at this then you know what it is. It is a rare, unique, powerful (SSM), and beautiful sounding analog polyphonic synth. It is in good physical and functional condition. It plays well with a few quirks, but thats how these DK's are.

It has been used sparingly in a pet free, smoke free, climate controlled, adult owned home studio. It comes with the dot matrix printed ORIGINAL INSTRUCTION MANUAL! Which I have never seen anyone else have. Its also labeled as 'Preliminary' which is interesting."

Siel Opera 6 Siel DK600 - Final Systematic Testing

video upload by tonetweakers

"Here’s the Seil opera 6 (also known as the siel DK600) that we just finished servicing. This instrument was serviced by another tech before our customer bought it. That tech did a bad job, requiring us to waste many more hours fixing what he failed to fix. This is unfortunately common these days with lots of unqualified people trying to save money by doing repairs themselves. As you can see from the video, it’s now in perfect working order. We tend to avoid dealing in SIEL products because the value of the time it takes to properly service things to our standards can exceed the value of the item itself. Here’s a rare opportunity to buy a Siel Opera 6 from us. It’ll be up on our website soon."

Keytek MDP 40 Midi Digital Drum Machine

This one was spotted and sent in by swissdoc.

You can find an overview video of the RMP 40 branded version posted here.

via this listing

"This is a very desirable VINTAGE, FULLY FUNCTIONAL classic drum machine from the 1980's (released in 1986), the SIEL MDP-40...also known under other brands as the SUZUKI RPM-40 and the KEYTEK MDR-40. It was made in Italy, and features 10 pads for 13 PCM sounds, 3 of which are accessible by external MIDI only. This machine comes with original power supply and owners manual. The unit itself is a desktop model, has LED display, is lightweight (only 1 kg), will also operate on 6 x AA batteries, and has 3 MIDI ports. Audio output is via 1/4" phone jack, mono out. I hate to let this go, but I haven't taken the time to experiment with it in recent years as I had hoped to do, so I'm passing it on. I envision it to be very useful in live performance situations as a trigger machine MIDI'd to a more modern drum machine with tight, up-to-date drum/percussion sounds."

P.S. Moby owned one.

Ultra Rare Synthesizer Kitchen Jam

video upload by CleverJoe Music

"Off the cuff music looping with the Siel DK700 and Arp Pro Soloist synthesizers to help stretch their legs. Both synths have been stored for awhile (the Siel for over three decades!). I'm running both synths through the delay and reverb effects in the Boss RC-505 loopstation. I also have the Siel Expander 80 which I'll explore in a future video."
