OXI CORAL – Polyphonic Multipart Synthesizer || How to Operate

video upload by Robots Are Red

"In this video we take a look at demystifying the Oxi Coral polyphonic synthesizer eurorack module. Coral is basically 8 Mutable Instruments Plaits in one with more envelope control, filter, chorus, space reverb, and a wav player. You can use it as an 8 voice polyphonic synthesizer, or as a full on groovebox synthesizer with up to 8 different midi parts.
This video goes over all the functions and functionality of coral, how to assign groups, saving & loading presets, and CV control (and assignment).
This is not a sound demo for all the different synth engines. Think of it more as a video manual.
(Note: In the video I mention Coral accepts Type A midi, it also works with Type B midi as well)

Musical Moment - Euro Rack Synth at Tavo Coffee

video upload by joey lopez phd

You see people with their laptops at coffee shops. Why not synths... Someone should bring a huge 5U system in, or a CS80.

"I got to hang out with Travis a local Euro Rack enthusiast at Tavo Coffee in Bryan, TX. This is a short video of clips I snagged with some sounds I created using the Apple Apple Moog Model 15 as I didn't get to record the synth. In a weird way having to go back and create sounds using a software synth taught me a lot about how synths work. I have used them before but each time I mess with them I learn that much more. I small euro rack synth seems to be in the near future."

SIEL DK-80 Vintage Analog Synthesizer Keyboard with Original PSU

video upload by scienceforce

via this auction

"SIEL DK-80 rare vintage keyboard synthesizer, produced in Italy in 1985.

It's a cool analog synth with digital controls. It is also bi-timbral with a split keyboard mode giving you 2 polysynths in one keyboard! 2x six point envelope generators, 2x 24 dB/octave low pass VCFs, 2 LFOs, 12 voices - 2 DCO's (sine, sqr, tri), 1 pink noise generator.

Another great feature is a 2-track realtime sequencer, MIDI In/Out/Thru and a NICE built in Chorus."

"Rough Mix Demo

Still included Mixing, some 700S harmonies."


video upload by Signal Sounds

"I thought I'd make an experimental noise and drone rack. My noise sources are the Apollo View Allscillator and the Worng Electronics Acronym. They are going into the Tangle Quartet VCA and being fed through the Apollo View Rabbit Hole - which, by the way, is also capable of generating sound with the feedback switch. From there we go into the stereo filter Parallax. I'm using the Instruo Cnoc (an ablsolue gem of a module) do to cover most of my modulation needs, with the help of Pam's Pro Workout. Beads is always on hand to add some weird magic, and the FX Aid is bring the huge reverb trails.

Every way the CS70M is BETTER than the Yamaha CS-80!

video upload by Vulture Culture

"Many people do not know about this rare, vintage synthesizer, the "update" to the greatest analog polysynth of all time. The CS70m was Yamaha's last chance to capture the analog synthesizer market before they went all in with digital synthesizers like the DX7. Today there are less than 1,000 that have survived. I think this synthesizer should be considered as legendary as the Roland Jupiter 8, Juno 106, Sequential Prophet 5 and Oberheim OB-X. It's older sibling, the Yamaha CS-80, was championed by Vangelis, who wrote and performed the score to Blade Runner.

Reco-Synth - Unboxing and assembly of the cabinet / Abertura do produto e montagem do gabinete

video upload by Fernando Costalonga - Keyboards, Synthesizers...

"Saudações! Este é um kit para montar da #Reco-Synth. Será um synth #monofônico modular. Nesse vídeo, efetuei a abertura da embalagem e montei o gabinete.

É uma experiência nova: montar o próprio #sintetizador, peça por peça. Também, ao mesmo tempo, vi que estou aprendendo o nome dos componentes de eletrônica e manusear solda é algo novo para mim. Mais à frente, estarei fazendo os próximos módulos e irei postar o progresso dele."


Greetings! This is a kit for assembly from Reco-Synth. It will be a monophonic modular synth. In this video, I performed the unboxing and assembled the cabinet.

It's a new experience: assembling your own synthesizer, piece by piece. Also, at the same time, I realized that I am learning the names of electronic components, and handling soldering is something new to me. Further down the line, I will be assembling the next modules and will be posting their progress."

Ambient jam with Dreadbox Nymphes, Tasty Chips GR-1, Walrus Slöer, Meris LVX

video upload by Jay Hosking

"Please support my work on Patreon:
A live, semi-improvised synthesizer jam performed entirely on hardware.

In my previous video, I tried the Walrus Slöer reverb pedal with a few fun synths. During that session, I stumbled into a chord progression on the Nymphes that sounded really lovely with the Slöer, and this track was born from it.

I knew it needed some accompaniment that matched the feeling, so I brought out the GR-1, my favourite granular hardware. With its four-layer timbrality, I could both create textures, and also use a timbre to double the Nymphes for some building/progression. I'm really happy with how hardware explorations can quickly lead to finished songs, and this is no exception.

Dreadbox Nymphes into Walrus Slöer - Pad
Tasty Chips GR-1 into Meris LVX - Four granular synth sounds
Arturia Keystep 37 - MIDI controller
Kenton MIDI Thru (not seen) - MIDI Thru

Performed and recorded live, with EQ, compression, and limiting on the master.

Thanks for listening."

"Due for original voice chip cleaning or replacement which is normal for these classics and also reflected in the price and condition of “fair.” Two of its voices are out: VCAs 2 and 4. Meaning the synth works in all ways but skips those voices when playing in poly mode. Unison mode sounds great, of course. But anyway you probably know the drill with these 106 voice chips. You can give the chips a bath in acetone and hope for the best or replace at ~$50 each. Replacement of all the chips at once seems to be the more convenient option, you usually get a discount for buying all six, and it is a permanent solution. I like doubleheart audio because they'll do the work for you and calibrate as well when you send them the motherboard. Estimated cost of chip replacement is $250 DIY to 300+ for full service."

Arp Quadra

via this auction

"Arp Quadra synthesizer keyboard that just got back from a full servicing by Synthchaser. Work included a complete re-cap, new slider pots (which can be led activated at a later stage if desired), new touch panel membrane and keybed refurb. It's fully functional and good to go. We have a long demo video made by Synthchaser we can share on request. The only issue worth mentioning is the lower transpose button is not working, but the upper transpose button does work and performs the same action. We have sold Arp Quadra's in the past for $12k - $15k and it's been a couple years since we last listed one for sale. These are very cool vintage analog synths."

8/6/23 Roland SBX-80 plays its metronome and pings General Radio 1564-A + Univox ProVerb

video upload by Cfpp0

"The Roland SBX-80 does a lot—SMPTE, for one thing, but it gives you clock on TS, clock on DinSync, clock on MIDI, manual tap tempo, and so on. It was the master clock around here until Pamela’s New Workout took over. The SBX-80 looks like a 909, and has a cool numerical grid of buttons like the old keyboards (back when mice had wires). Here the SBX-80 is playing its metronome at a lugubrious 20bpm. SBX-80 metronome audio out to Univox ProVerb for some spring reverb. SBX-80 time base out to audio input on General Radio 1564-A Sound & Vibration Analyzer, with band level at 70 3mV, then 60 1mV, then 50 .3mV, with bandwidth at 1/10th octave, and frequency at 3.5, then 4, and back."
