Siel Opera 6 Siel DK600 - Final Systematic Testing

video upload by

"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."

SIEL 80 Synth Test with Notator MIDI CC's.

video upload by loksync

"Testing out the SIEL80 synth and Notator's Realtime MIDI Generator on the Atari 1040STE.
You can control it's parameters over MIDI CC.
It uses an SSM filter.
I recorded the audio a bit too hot so it clips a bit."

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."

Thought the stand was kind of interesting on this one.

"Late '70s/ early '80s Siel Orchestra analog polysynth. Same keyboard as the ARP Quartet, which was this synth rebadged for the US market."

"The instrument bears the weight of its years, therefore it shows normal signs of wear. It was serviced a year ago. After which it was put back in its original case, now the vibrato turns on but doesn't work. That's why the price is lower. For the rest everything works fine . The Animator selector has been replaced with a compatible one."

"This Siel OR 400 Synthesizer is owned by Tycho

There are a handful of scuffs and scratches here and there as well as some dust and grime. The unit functions, however there are a handful of issues with some of the parameter knobs/faders being very scratchy—especially the volume fader. This unit will benefit from an overall tune up/clean to get it to function at 100 percent.

All items in The Official Tycho Reverb Shop ship fully insured with delivery confirmation and a signed and embossed Certificate Of Authenticity from Scott Hansen."
