Cyclon Ltd. ME Analog Synthesizer

"80er Jahre DIY Synthesizer, Projekt"

Note there are two videos in the playlist above that appear to be the same. Including both in case one is removed. Use the player controls to skip to the next video if the first disappears. I also captured a few screenshots below. Click on them to zoom in. That out of the way, if anyone has any additional info feel free to leave a comment. This is the first post to feature Cyclon Ltd on the site. It appears to be a prototype and/or DIY, but who knows... If you know, leave a comment. Note the center Cyclon appears to be CYCCON, but you can see elsewhere on the synth it is Cyclon.

Check out the New Old label for other rare and older synths making their first featured on the site.
Check out the Exclusive label for posts featuring the rare of the rare. There is of course some overlap.

PPG Wave 2.2 2.3 Meticulously Refurbished ToneTweakers Sounds Patches Demo Factory Presets

video upload by tonetweakers

"Here’s a run through of the sounds on the PPG Wave 2.3 we are about to put up for sale. We meticulously refurbished it and are in the process of systematically testing and photographing it. This unit was upgraded from a 2.2 to 2.3 but it’s previous owner (who was the original owner). The sounds heard here aren’t the greatest but give you an idea of it’s overall tone. In the hands of a good programmer, this synth is magic! For sale very soon on our website. We buy, restore and sell PPG synthesizers and other great vintage synths."

Eurorack Formant Filter Comparison

video upload by John Schussler

"I now find myself with 3 separate filters that do "formant" filtering, so clearly it's time for a comparison. I'm literally getting my ya-yas out. And my yi-yis, and sometimes my wa-was. Just depends on where you turn the knob....

There are other formant filters out there, this isn't all of them, but it's all the ones I have, so don't assume this is the exhaustive comparison.

Formants are fun. And though I don't get into it much in this video, using formant filters for "regular" duties with only mild formant effects can be quite interesting.

Actually, using formants sparingly should probably be the rule. There's definitely too much of a good thing possible here....

Koma Komplex Elektronik Sequencer Update

via Koma Elektronik

"The long wait finally ends! Due to the supply chain disruption caused by Covid-19 we had to scrape together parts from all corners of the world for nearly two years. Finally the last necessary chip has found its way into the box labelled "Komplex Sequencer". We are now able to start producing a "golden sample" and organize a full production run.

First 10 persons pre-ordering will receive 10 KOMA Elektronik branded patch cables with the perfect size to internally patch the Komplex patchbay

What is a "golden sample" and why is it necessary? First off: NO, there will NOT be a Komplex with an enclosure made out of gold (at least not in any forseeable future). But whenever a "complex" product like the Komplex undergoes some bigger changes, KOMA usually won't just go ahead and change a bunch of circuitry to willy nilly start production right away. Instead, great care is taken and a so-called 'golden sample' is produced. This means that all changes are worked into the circuitry and a single prototype is being built to be tested thoroughly.

We added a new functionality into the Komplex Sequencer: The Transpose CV input now also transposes the MIDI notes that a sequencer is producing. Also some circuitry had to undergo changes to account for non-available and now obsolete chips. We already have a prototype here with the necessary changes but it still has a bunch of colored wires dangling out of the enclosure and the changes are essentially piggy-backed on the original circuitry. That's why we are producing a golden sample right now as you read these lines. Once that prototype comes back and is all good, we will trigger production.

The new Komplex run is very limited and will be available in 2 batches of 25 pieces each. Some of you that were eying the Komplex for a longer time might have noticed that the sales price increased. Unfortunately many components needed for building a Komplex sequencer have gotten more expensive since our last production run. In fact, it is fair to say that ALL components have gotten substantially more expensive. This starts with electronic parts not available on the market anymore, like microcontrollers that we had to buy for an elevated price, goes over hardware parts like sliders and pushbuttons and ends with greatly risen prices for both the metal enclosure and wooden sidecheeks.

Since demand is huge, as of today, we have enabled backordering of Komplex Sequencers in our webshop. We have already ordered a few components like the metal enclosures and wooden sidepanels but the majority of production will have to wait until the golden sample is here. Since we already tested the new functionality and can verify it with our 'Frankenstein' unit here, it should be smooth sailing from here on out. In fact, we are testing this feature since nearly a year in our synth setup in the workshop and enjoy it thoroughly.

Current estimated delivery date for the first batch is September 2023. That's how long it takes for all the necessary parts to arrive in our workshop plus assemble time. It is "first come, first served" or as you programmers like to call it: FIFO (first in, first out)."

Sequencing with the Sequential: Prophet 6 + Korg Sq-64, just the perfect combination!

video upload by Agustín Spinetto

"I spent an afternoon creating some melodies with my Sequential Prophet 6 and the modular synth, all being controlled by the Korg SQ-64. Rhythms comes from the Plaits module, melody from the Pico Voice and the chords are from the one and only, Prophet 6. Hope you enjoy it!"

Patching: Creative Clocks

video upload by Qu - Bit

"In this sample-based patch, we're getting a lot out of the Sonar output on Nautilus.
It's a "lively" signal, so we've attenuated it a little before sending it to the Rate on Bloom.
You can see Blooms' clock go wacky (as in, awesome) as Sonar churns out stepped random goodness.

About 'Patching'.
This series continues to be a reminder to us, and hopefully to you:
Take the time to stumble in the dark a little...figure something out...control some voltage...
...enjoy PATCHING.
In our videos (moving forward from this one):
Purple cables = audio
Blue cables = CV/gate
White cables = clock"

Vintage MINI GAN Electronic PET-103 Organ Synth Kit

video upload by David Hilowitz Music

"I recently purchased a super rare analog synth kit from 1979 (MINI GAN PET-103). In this video, I put the synth together and find out how it sounds.

The sample library I made in this video can be found on the Patreon:

PCB and schematics for this synth can be found here (thanks to Håvard Kristoffersen):"

Found the video after seeing the following listing for one:

via this auction

"New old stock MINI GAN Electronic PET-103 "organ" kit.

Super cool electronics kit from 1979.
It comes with everything that is pictured.
I think it is complete, but please review pics to determine that for sure.
Some components may not be good any longer (like the electrolytic caps).

Nothing has been tested.
It has vintage dust and etc all over it, needs to be cleaned.
This is not returnable for any reason.
Sold as-is, for parts, or restoration."

Soundforce (µ)CHORUS / nostalgic and versatile eurorack chorus / first jam (inc. all the mistakes)

video upload by BRiES

"In this very first jam with these modules by Soundforce I'm figuring out what to do as I go. Keep in mind that this isn't necessarily the best representation of the capabilities of these modules, nor is it a demo or tutorial.

On the big one I cranked the mix slider to be 100% wet, which gives a wide stereosound that I really really like (especially in manual mode) but the original Roland Juno chorus (and the µCHORUS) is only 50% wet. But hey, these parameters are there to use and abuse!"
