"There are only 190 Rev 1.0 ever make, likely far fewer are operational now. Mine is like a Rev 2.0 in that it does have Cassette Interface and Patch Storage. Not all Rev 1.0 Prophet 5s have this.

Contrary to popular opinion, this synth can be upgraded MIDI using Rev 2 Kenton kit, since Rev 1.0 and Rev 2.0 Prophets are nearly identical. Mine is even more rare due to having cassette interface, not typical for a Rev 1.0.

"This Multimoog is in good condition, there are signs of wear throughout the body and some small cosmetic damage but nothing too serious. This synthesizer comes equiped with a 44-note monophonic keyboard with aftertouch, a ribbon-type pitch bend controller, and an external control voltage and trigger inputs/outputs for interfacing with other synthesizer equipment. The knobs work perfectly fine but the cover underneath the knobs is starting to bend and peel as you can see in the pictures provided. The Moog Multimoog Synthesizer is in working condition and turns on and works as in tended."

Soviet Solaris Estradin 314 demo proj3

Update: this one is currently for sale on Reverb here. Pics captured here.

"A bit of a meander through this fascinating and wild analog poly / organ.

As you can see, it’s in excellent cosmetic condition. Sliders all slide fairly smoothly. A proper power cable was professionally installed, as the one it came with didn’t fit snugly. It still uses 220V though, so a converter is required.

Now, much as I love it, I can’t say for certain that this Soviet-Era instrument is functioning 100% optimally. After all, I don't speak Russian, and I've never encountered another! You can probably hear the slight hum -- though the signal-to-noise ratio easily masks that when playing. Perhaps it could use a tune-up?

I’ve always found the unit perpetually intriguing. One minute it’s a 60s compact organ (w. a filter!), the next a 70s string machine, then a growling 80s analog synth bass, and then blammo: a rocket ship. I mean, c’mon.

If your path in life leads you to encounter a Solaris Estradin 314, maybe bring it home?
Thanks for watching.

Wonderful description from the web:

Vintage rare soviet analog polyphonic synthesizer - SOLARIS Estradin-314. Produced in the USSR on "Estradin" factory in Zhitomir city (famous for its Estradin-230 & Altair-231 synths) in 1988.

SOLARIS uses organ style drawbars to create the basic tone, and has a analog filtering as well. Inside it has 12 voice boards that correspond to each key in an octave, and then uses a divide down system to get to the other octaves. The filter is really extreme and sounds fantastic, as well the envelope is really punchy, so you get great synth stabs, sweeps and percussive organy sounds.

If you use the envelope and filter sections carefully you can get great moogy leads out of it, warm organ sounds, flying ambient textures, in the high resisters it can sound like a string machine, or even a theremin if you crank the resonance.It has tons of character and can sounds amazing!"

Critter & Guitari - Additive Synth for Organelle

"Additive Synth is… well, an additive synth! Use the Organelle’s knobs to change the transposition, select a waveform, or accentuate specific partials. Loop it up with the built-in sequencer!"

G-Storm Electro Delta VCF Version #2 Demo Korg Delta/Poly-61 Filter Adaptation Eurorack

"Audio and Video by G-Storm Electro c.2018

My first video of 2018, I know it's been a while. I have been busy working on this little beauty! Today I introduce my Delta VCF version #2. You will remember the Delta VCF is my fully analog filter adaptation of the Korg Delta/Poly-61 synthesizers with the addition of a 2-Pole mode. My version #2 is exactly the same sound, functionality, and circuit as the version #1. It has a revised panel layout that makes the trimmers available from the front, is 12HP, and is now skiff-friendly. While we're at it, I audition some sound examples - starting with some PWM bass sweeps. I have trimmed the resonance for the module I am showing today so that it could self-resonate, I modulate that with an LFO. Audio recorded direct to Tascam DR-05, no effects or EQ added."

3 Modules #41: Kinks, Braids, Rings


Published on Jan 11, 2018 Comparative Irrelevance

"I wanted to try a little idea for Kinks this time: to split a random S&H sequence into two different sequences using the logic and signal processing sections.

Patch notes:

A slow external clock gets the S&H sequence going, and this is sent into Kinks' LOGIC section. Since the noise that's normalled to the S&H input is bipolar, the resulting S&H sequence contains both positive and negative voltage steps. We can take advantage of that, along with the fact that the logic inputs are normalled to 0V, to split the sequence into only the negative and only the positive steps. The S&H sequence goes into the LOGIC input A, and the Max and Min outputs contain only the positive or the negative steps respectively (and otherwise rest at 0V). Finally, I'm using the signal rectifier to flip the "negative sequence" to positive.

Braids and Rings play the sequences. Braids is in WTx4 mode (4 voice wavetables playing chords) and I'm using a version of the Rings sequence to modulate Color, which chooses what kind of chord is played. I'm also using the internal envelope/VCA and quantizer here.

Rings is in Karplus-Strong mode, and I'm sending it white noise from Kinks in order to make sustained notes.

As you can see I'm using the volume controls on my µJack to mix the two voices together – the stereo output signal is summed to mono in the mix.
