Meet the M0SS 101 Synthesizer by Andrew John March
M0SS 101 DEMO video upload by Andrew March
"A quick demonstration on how to build a patch with the M0SS-101 synthesizer."
From the creator of WVR, the the M0SS 101 virtual analog monosynth is currently seeking funding on Kickstarter.
"M0SS-101 is a virtual analog monosynth built for a pure, hands-on subtractive synthesis, packed into a compact, rugged guitar pedal enclosure.
With 26 buttons and a single encoder, M0SS-101 gives you intuitive access to a deep 42-parameter virtual analog synthesis engine. Press a button to select a parameter, turn the encoder to modify it, and monitor your signal flow via the LED system.
Using a MIDI controller, you can map any parameter via simple MIDI learn, making it easy to integrate into your setup. Up to 17 presets can be saved and recalled for quick access to your favourite sounds.
The 26 RGB LEDs use colour and brightness to represent signal flow, modulation paths, settings and selections. A separate row of 11 LEDs at the bottom gives you instant visual feedback on the currently selected parameter. I aim to offer an affordable, compact, and versatile instrument, without sacrificing features, ergonomics, or most importantly, fun. I hope you'll enjoy playing this synth as much as I have :'-)"

"KORG Mono-Poly & Kovari Midipoly retrofit 372767 Original Korg Mono/Poly with Kovari MIDI retrofit - specifications available online New baseboard and custom plywood side panels Very tidy - camera shows every speck of dust Front panel Excellent All pots clean and noise free Voices fully functioning but will require calibration to ensure optimal output
DESCRIPTION: I acquired this fully functioning MonoPoly some years ago, but the case was in terrible condition. I cut a new baseboard from MDF, and then cut and installed new marine grade plywood side panels. The front panel is in great condition, but there is a slight defect on the mod wheel assembly panel as per the condition I acquired. All pots are noise free, as are the outputs. She sounds amazing in Poly Unison mode, but the individual voices do drift a little. She would benefit from a comprehensive voice calibration, but I don't have the instruments required to do so. Once she is fully calibrated, she will sound even more awesome. She comes with the Kovari MIDI retrofit, which allows her to integrate in to any modern MIDI studio. Very sorry to see her go, but I just don't have the space for my full hardware studio any more."

Korg Mono/Poly garage-find | Did it still work after all those years?
video upload by Espen Kraft
"The Korg Mono/Poly belongs to a friend of mine who (if my memory serves me right) did find it in a garage somewhere, alongside a Roland Jupiter-4 which was beyond repair from what I can remember he said. This is a short edit from a longer video I once had on my channel.
Oscillator 1 on the Mono/Poly did not work and that prevented me from doing a couple of things with it, but it still worked and what you hear in this video is what I got out of it. Only the kick drum is a sample. The rest is the MP you see here.
Since this video was made the synth's been repaired/restored and is now working 100%. The dust did come off.

Multipoly: Unbox, blather and some custom arp sounds
video upload by Richard DeHove
"I remember my Korg Mono/Poly with great love and nostalgia. My first synth, the machine that taught me about synthesizers, the machine I used in all my early live gigs. Many machines have been bought (and sold) since then trying to recapture some of the weird-arp magic. So the Multipoly was a natural.
Here I can't help but blather about such things and play my first few custom sounds using the Mono/Poly starter template.
Overall I'm extremely happy with it. It's complex, somewhat unfriendly, very menu-divey but has so much going on that the amusement longevity factor and overall usefulness score seem high. Strangely, the only area that has attracted no love from Korg is the arpegiator! Everywhere else there are options galore, but for the arp, almost nothing more than the original Mono/Poly offered. Hopefully in an update we'll get separate arps for each layer - at least.
For those who just want to hear the damn synth without my babbling over the top, there's a no-talk version on Patreon.

What's REALLY the Best Era for Synthesizers?
Note: Auction links are affiliate links for which the site may be compensated.
video uploads by Vincent Presley
Found the above in the listing for the Moog Sonic Six further below.
"Breaking down the last 50+ years of synthesis into 6 eras and finding what era is really the best.
Everybody likes different stuff so hopes this is somewhat useful to people."
Playlist including the list of synths:
1. What’s REALLY the best era for synthesizers? Part 1: 1970 - 1978
And the Moog Sonic Six via this listing
"Beautiful 50 year old Moog that can do things no other Moog can do. It's the only Duophonic Moog! You can set one osc as low note and one to high note for duophonic playing, set it as a mono synth, or even change the scaling of the high osc for microtonal playing. This Moog has the same oscillators and filter as the Minimoog Model D but instead of the Mini's third osc that doubles as it's only lfo, the S6 has TWO dedicated LFOs that can have separate wave shapes and rates and can be modulated by the eg! Modulation craziness. This Moog also has TWO amps! One signal goes through the filter, as usual, but there is a second amp that bipasses the filter. This means you can have a high resonance sweeping filter sound going (which kills all low end on every Moog) but you can beef it back up with the dry out amp. I've had most Moogs and think this is by far the best and most powerful Moog. I passed on a Minimoog for only 3k years ago and sold my Multimoog when I got my first S6. Everything works. Tuning and scaling was just adjusted and it's working great. I barely play it and have some studio changes in mind so it's on the chopping block. Sold as-is. No returns and I am not responsible for any guts getting shaken during shipping. It's 50 years old and it's in excellent shape for that age. Tuning and calibration info can be found online if you need it after shipping. Also considering selling the Polymoog 203a seen in the photos which is also fully functional and includes the rare Polypedals. A little demo video of the two can be seen in the link. The S6 tune drift in the video is actually a slow LFO and not just drifting. Also the video was done before I tweaked the scaling pots inside."

KAWAI K3 - Synthesizer Review, Sounds & Demo
video upload by synth4ever
"The Kawai K3 is a 6-voice digital analog hybrid synthesizer. It has 33 waveforms, including one additive waveform that can be edited and saved. It also features 2 oscillators, noise, an SSM filter and envelope, VCA and envelope, an LFO with multiple waveshapes (routable to oscillator, filter or VCA) and it has a velocity and aftertouch sensitive keyboard. It unfortunately does not have oscillator sync, PWM, ring modulation or a mod wheel.
The Kawai K3 synth has 7 different types of effects (6 chorus, 1 delay), keyboard tracking, portamento, mono mode (unison), and MIDI in/out/thru. Despite the membrane panel buttons, it is fairly quick to edit with the jogwheel. The build quality is substantial thanks to the metal frame.
The Kawai K3 is somewhat obscure and is great for dark pads, icy tones, PPG-style timbres, bell sounds, basses and related wavetable types of sounds. It was competing with the Korg DW-8000 but also other synths including the Yamaha DX7, Roland Alpha Juno and Roland JX-8P. It has its own distinct sonic character and can also be expanded up to 12 voices by poly-chaining it to the K3M rack (spillover mode).
The Kawai K3 is a great 80s hybrid synthesizer and can still be found on the 2nd hand market. With more recent 3rd party controllers, you can also add knobs to the synth for enhanced real-time control. If you have the chance to try a Kawai K3 I would recommend it, especially if you like PPG Wave types of sounds."

Korg multi/poly Analog Modeling Synth: First Look!
video upload by Keith Crosley
"The latest Korg R&D synth—the Korg multi/poly—just dropped outta nowhere, and I was lucky enough to snag one in stock (thanks, Zzounds!). Let's take a look and listen to this super-interesting, super-fun, badass monster synth. In this video, I'm mostly talking about what's new and different vis-a-vis Korg wavetate and modwave. We'll surely be doing more videos about this thing in the future. And, OF COURSE, you can use KRC Mathwaves with it, 'cuz wavetables. Grab your waveshaper and get ready for some virtual-voice-cards-a-go-go virtual analog goodness! (Spoiler alert: My quick review is this synth is rad.)"
