"The Sine Community had the opportunity to interview Girts Ozolins and the team at Erica Synths in Berlin, Germany. Get an inclusive insight and learn more about the people behind this Latvian Eurorack manufacturer based in Riga.
The Erica Synths team is made of visionaries, engineers, musicians and our most important employee – Tuna the cat. Over the last couple of years Erica Synths has been working hard to create Eurorack modules and desktop instruments that make a difference in your workflow, whether for production in the studio, live performances on stage or educational goals in the classroom. They strive to offer the highest possible quality, aesthetics, sound and function.

Moon Modular: 502D VCA/ Ring Modulator
Club Of The Knobs: C911P Poly EG
STG Soundlabs: Envelope Generator
Reverb from Lexicon MX400 and Strymon BigSky."
3rd Wave Update // PPG mode + Prophet VS waves
video upload by Starsky Carr
"As the spiritual successor to the PPG Waves the 3rd Wave has some secret sauce hidden under the hood to give us the same vintage vibes as the original PPG. And it just so happens this also works for the Prophet VS waves. The way the samples are processed gives us all the lovely 80s musical artefacts that make the classics so special.
Here I demo the Prophet VS waves and show how to load PPG style wavetables. So ... effectively we have a Waveterm - we can load any 128 sample based wavetable that has 64 waves.,
Check out my wavetable vid for some tips on how to do that." [posted here]

"Korg ARP 2600 FS vs Behringer 2600 - what's the difference?
We'll look at the features in common to each as well as the differences.
Check it out!
If someone offered you either synth (and you could not sell it), which would you prefer to own?

"Duo_ is a Modular Synth with portable case, compact design and pure analog sound. No pre-connection and a 80-patchbay jacks you can basically create everything, but the charm are the complex patches for extremely unusual modulations, clicks, bleeps & laboratory sound, anyway is possible make fat bass lines, leads or the characteristic retro sound of Vintage Synths. It´s a friendly start in the world of modulars, but also is a good complement to your system!

Pics of the inside below.
"This early Tonus era ARP 2600 synthesizer had oscillator sync added at the factory and also had its keyboard upgraded to the later 3620 model, which is duophonic and includes an LFO. The factory also installed the PPC (proportional pitch control) - a very useful pitchbend and vibrato mechanism found in the later Odyssey and Axxe. There was also an additional gate input for the AR envelope added too, so this arp's 2 envelopes can be gated independently.
We meticulously disassembled, cleaned, refurbished and future-proofed this unit, sparing no expense - a process that took a whopping 60 hours of skilled vintage synth tech labor, plus parts costs. It's now working like new again and will hopefully be much more reliable than any other of its type out there. The value of this work is of course included in our price which is justifiably higher than lesser examples of this beautiful classic instrument often being sold by amateurs disguised as store owners on a popular website.
We did lots of maintenance and preventative work to this instrument, including the following: All tantalum capacitors were replaced, the power supply was rebuilt, the faders, jacks and switches were properly cleaned and are free of crackle, the keyboard was fully rebuilt with new bushings, keys removed and cleaned, the unit was recalibrated, replaced many terminals / molex connectors to greatly reduce the chance of connection issues, cleaned keyboard connector, key contacts and bus bars, replaced cinch jones receptacle, etc. There were a few other things done along with any necessary repairs.
The added oscillator sync makes it possible to make much more interesting sounds than any stock 2600 can. A CMS 4012 filter module, well known for its high quality sound, is installed in this unit. This 2600 has been tested systematically multiple times over many hours and is working perfectly and sure to make its next owner really happy!
Part of the extensive restoration process included re-coning the speakers. During final testing, we noticed what sounded like a slight distortion coming from the speakers that we determined was actually due to the 2 pieces of speaker cloth originally present in this unit between the speakers and the front panel, so we removed them and put them in a plastic bag which is now inside the unit in case whoever buys this unit wants them."

"This unit was meticulously refurbished and future-proofed and is therefore better than the vast majority of 2600s now since we go above and beyond other sellers to ensure our ARPs are not only working perfectly but that they will hopefully outlast all others too. This process required 40 hours of skilled vintage synth tech and was done to the highest standards. In addition to any necessary repairs, work performed included: keyboard rebuild, power supply rebuild, speaker reconing, replacement of all tantalum capacitors, cleaning inside and out, cleaning of key contacts, slide pots, switches, replacement of molex terminal connectors and recalibration, etc. This unit is now in perfect working order and is sure to make its next owner very happy.

"Meticulously overhauled by the most critical professionals around and working perfectly, no excuses or surprises typical of most vintage sales these days.
In addition to any repairs, we paid our tech to do the following work to this example. Some of these are things we typically do to our Xpanders during restoration and some were to fix an intermittent tuning problem this unit had when we bought it from our customer who we believe was the original owner:
Recapped power supply
Cleaned panel and chassis
Removed, cleaned, lubed memory switch
Cleaned all other switch contacts
Replaced hinge screws
Replaced 2 output jacks
Modified panel overlay to resolve typical sticking switches
Cleaned all IC sockets
Resoldered IC sockets for all EPROMS and all RAM
Replaced several IC sockets
Replaced all operating system IC chips with new ones, latest version (2 for voice board, 4 for CPU board)
Replaced battery
Reloaded patches
This process required 30 hours of highly skilled vintage tech labor plus parts. This one had tricky problems that ended up being due to bad IC sockets. The problems were intermittent - the unit would sometimes work fine but would sometimes malfunction. Those are often the hardest problems to fix because you have to get them to recur. Our typical burn in process after servicing items is long, but in this case, we ran it even longer and shook it up a bit after figuring out and fixing the problem, just to be absolutely sure it was working perfectly, and now it is, so it's ready to make its next owner very happy!"
