"Rare vintage EPro Minisynth analog synthesizer keyboard. This was made in Holland in the early 1980s. Operates at 220v (you'll need a 110v step-up transformer to use in the USA, an approximately $30 part, we can make recommendations for one if needed just ask). Apparently only approximately 25 of these units were made, possibly made by the company DGS which had manufactured two synths, the Scorpion and this Mini-Synth. It looks similar to the Holland made Synton Syrinx from the same time period. This is a CEM based synthesizer with loads of CEM chips inside. It's in great shape for its age and fully functional. Sounds lovely, a unique rare synthesizer."

A synth that talk - AnalogFX SER-2020 Demo

"Today I'll show some cool sounds and set up with the SER-2020 by AnalogFX.
This is an analog monosynth based on the Synton Syrinx, wich means it's quite an unusual design compared to your classic Minimoog or SH-101.
I find it hard not to think about Aphex Twin when playing with this, hence the click bait thumbnail ;-)"

Towering Bass Patches | Gyrinx VCF Filter [Demo 5]

video upload by gstormelectro

"Audio + Video by G-Storm Electro c. 2023

Today I'm auditioning a few humongous bass patches featuring the Gyrinx VCF, no effects. Feeding only a couple of 101-VCOs and Pittsburgh DNA Symbiotic Waves. Modulation by 2xADSR and Feedback Modules LFO, Sequenced by Keystep Pro. Headphones or good monitors recommended. Recorded direct to Tascam DR-05, no other mastering just a little normalization.

Gyrinx VCF is a eurorack filter inspired by the vintage Synton Syrinx filter section using Alfa AS3350 chips. Check my Reverb store for Gyrinx-VCF availability" *BLOG* http://gstormelectronica.blogspot.com/

Unboxing // AnalogFX SER-2020 // Part 2 // No Talking

video upload by LESINDES

Part 1 here

"Rebuilt of the ultra rare SYNTON SYRINX Dutch keyboard synth.
I cannot compare but the unusual filter setting of
2 bandpass and 1 lowpass VCFs, with 4 different routings
give a lot of modulation freedom and rendition of rather unusual
sounds.

Since I am not a fan of black gear. I tried my best an contacted
ANALOG FX. And they had been so kind as to manufacture a
custom blue face synth which I have only seen in some
preproductions units and, of course, in the historical
SYNRINX which was available also in red.

So this is the first touch of synth tweaking is a bit rough
sometimes ;-)

Have fun!"

Epro E-Pro Mini Synth SN 0158

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

via this auction

"Made in Holland in the early 80s the same period as Synton released their Syrinx synthesizer. According to Dutch Sources, Only 25 units are known to have been made and this is one of them! It is a fully CEM based synthesizer and you hear that. It sounds very warm. The synth has been serviced and is in good working condition.

Cosmetically it's in nice condition as well with only some minor scratches, some wear and tear, and the wooden side panels have little signs of use (see photos). Overall it's a great piece of history that deserves a good new home. It's a 220v version with a European plug installed, 220v step transformer required for USA power, and required for most countries outside the EU in general. The serial number is: 0158."

G-Storm Electro Gyrinx VCF Uninhibited Functional Testing Audio [Demo #4]

video upload by gstormelectro

"Audio + Video by G-Storm Electro c. 2021

Been short on time through the holidays, so I thought I would make a quick video while I work :D
This one is an uninhibited functional testing routine I'm performing on another batch of Gyrinx VCF modules for sale.
It is very revealing as to the sound character as I quickly run through all of the functions of the filter without thought to sound design.
Sound source is Pittsburgh Modular Primary Oscillator saw and square.
Off camera I have a Batumi for LFO modulation.
Sequencing by Keystep Pro.
No added effects or processing, recorded direct.
Watch your levels using headphones, some harsh tones ahead.
