SIEL MONO Analog Synthesizer 1979 | HD DEMO

(c) 2019 by AnalogAudio1

I played the Siel Mono partly with reverb effects from a Lexicon MPX 500 and delay effects from a Korg SDD-3000. But no chorus, phaser or other effects involved.

The SIEL MONO is a monophonic analog synth made in Italy. It's the only one mono synth from Siel (hence the name?). It has 10 presets (trumpet, flute, violin, you get the idea), but apart from that it's fully programmable. I has one oscillator, a filter with switchable LOWPASS / BANDPASS / HIGHPASS modes - and the best of all - all modes are combinable! 1 LFO (frequency can go very high), noise generator (white noise). It has a built in CHORUS effect, called "Animator". Very nice portamento effect, reminiscent of ARP Pro DGX and Minimoog (the portamento effect, not the synth). Surprisingly meaty, powerful basic sound. A clearly cutdown version of the Siel Mono is featured in the Siel Cruise.
My conclusion: Interesting synth, but very confusing and annoying to program. Parameters, which should belong to a certain section, are spread all over the place. A solution could be, to replace the switch/slider caps with color coded ARP-style caps (red for filter, blue for oscillator, green for LFO and so on). Editing will be a lot easier.

I love all those vintage Italian synth. That beast is a healthy mix of miniMoog D and miniKorg 700 with a slight touch of Arp Odyssey. Or it might be an Yamaha cs15 on speed!🤗👍

I've had mine for 38 years, and used to gig with a siel orchestra. used to use a set of Boss pedals.The delay was brilliant with the bass.

AHA! I think that's the one. Thank you for solving a mystery for me. I remember my parents drove us to Taunton because they were interested in buying a shop (they didn't in the end). While they were looking at the place they left us kids in a secondhand shop looking around, and I found a synth there, and until today I couldn't remember the maker. As soon as I saw "SIEL" in that font it looked familiar, and I remember the round slider knobs. I'm pretty sure it was this one :)

Wow. This has an incredible amount of character. Add it to my list!

5:02 That filter is so dirty it should be X rated.

It’s sounds so beautiful, love Mono synths

[richardvanenteren]

Nice😍. This was my first synth I bought. So cool to see and hear it again.

[hominidaetheodosia]

You can have any sound as long as it’s brbrbrbrbrbr zingggg!

Love it!

Would be cool to hear Jexus have a good old Mwarrrpp on it for a bit!

Wow, quite an interesting synth.
I remember looking for the Cruise as a substitute for the Korg Trident, thinking I would never be able to get one. Great to hear these sounds!

[joshuahelmeke]

That reverb really breaths life into the synth. Spiel made some of the best.

[longshotkdb]

... woh! amazing little piece of hardware you have there. love it.

[mu-soguy]

I think just thanks to the sheer variety of synths and the quality of editing this is one of the best synth channels on the internet.

Great video. Just bought a beaten up one. Hopefully I'll get her going again

[TelexToTexel]

It was sold new from Chase retailer in the UK, for just £99 in Feb 1986 !

I also have the SIEL Mono. Tons of sonic character, that you 've managed to bring forward. Mine needs some re-capping and slider maintenance as it shows signs of instability and wobbliness - especially in the envelope / filter sections. Great job once more, man!

Moto Bella!
An Italian synth fit for Giorgio Moroder himself.

C'è chi ha il coraggio di ridere di macchine come queste, e del suo fratello maggiore Cruise, che ho dovuto svendere per necessità. Non pensando che intanto sui palchi ci stavano e ci rimanevano.

[benthies]

Your playing always brings these synths to life and shows their full potential. Do you have any music recorded?

[retrosound]

Sehr eigenartiger Klangcharakter aber cool.

[Mattieval]

I've just found your channel and I'm loving all your videos. Have you thought of doing more digital stuff, such as one of the Virus synths?
