RF AD Multi Vco Krell patch

video by Radical Frequencies Modular

"The sound is directly from the RF AD Multi Vco into RF Vca.
Other modules used for this patch :
The RF dpvco as modulator for the fm and sync of the main AD multi Vco ,
The RF Vc Adsr which is the clock generator and envelope,
The RF Lucky Voltages as random voltages as sample and hold that send random values to Vc Adsr ,
4ms Pingable Envelope Generator ,
Euclidean Circles as sequencer ,
RF Quad Vca Mixer ,
And finally a Mutable Instruments Beads as delay reverb effect."

"An ultra rare mono synth from 1976! This often overlooked synth sounds great. It is capable of some really awesome early analogue sounds.

Only 100 units made, imagine how much left! It can make some weird noises largely due to it's retro-cool ring modulator.

You can also run external sounds through it.

It has two VCOs, two kinds of Ring Modulation, three kinds of Noise and the High Pass and Low Pass filter a featured on dual traveller sliders!

Oscillator Subtractive synthesis analog mono synthesizer with 2 VCO and portamento mode:

- VCO1: octave range from 64' to 2', tuning +/- 5 semitones, shapes triangle, square, saw, pulse, pulse with variable width. Also special external mode (see filter)

- VCO2: octave range from 16' to 1, tuning +/- 5 semitones, shapes saw, Ring modulator 1/2, Scale Noise, Pink Noise and White Noise.

FILTER The filter is analog (Traveler) allows flexible and sofisticated LPF, BPF and HPF with 'BRIGHT' which is the resonance.

ENVELOPE single EG generator "AR" Attack/Singing Level, the Range is based on 3 level presets

LFO Single delayed triangle modulator with variable depth and reaches a pretty high frequency for some FM modulation on pitch.

Also can acts as a simple VCA vibrato. It's got a fast envelope, auto bend, and LFO re-trigger too."

via this auction, also on Reverb.

"This particular example is in excellent condition. EVERYTHING works as it should. This baby is CLEAN. Even the battery posts are rust / corrosion free. Rare to find such a classic SH in this condition. The only thing to note is that the Portamento knob is slightly bent but works perfectly. Its been like this since i bought it years ago, just stating for full disclosure : )

Great bass / lead machine. So many hits made with this beast. Has a great sequencer / arpeggiator plus CV I/O. Use it as a sequencer for your other analog CV synths!"

A quickie with the Gerd Schulte Compact Phasing

video by Vintage Audio Institute Italia

"We had this hooked up and made a quick spontaneous video.
It's not always easy to dial in the sound you're looking for - if that's your thing - but you can sure get a lot of different sounds out of this pedal.
The machine generating bass and chords is a special little animal, more videos of that to come."

VAI 18 :Solina String Synthesizer

video by Vintage Audio Institute Italia

"One take just playing some chords on the Solina String Synthesizer - no over dubs.
Binson Echorec 2 is the effect source.

It looks like an inflated Solina String Ensemble.
Story goes that American ARP sent a bunch of keyboard-less monophonic ARP Explorers to Eminent in Holland in the mid 70's.
Eminent incorporated most of these synths in to a huge double manual living room-furniture organ that also included the Solina String Ensemble.
A small batch of ARP Explorers were left over and Eminent decided to make a limited, "lightweight" edition : A Solina String Ensemble combined with the ARP Explorer synthesizer.
Both fairly limited instruments on their own, the combination of a mono-synth and string machine make them become more than the sum of their parts.

Here in Italy there were many similar combos and the earliest one, The Farfisa Syntorchestra was released the same year, 1975.
Which one came first? We don't know, please use the comment section if you know the answer.

The possibility of routing the String Ensemble section into the ARP Explorer filter section is a great tool, the filter of the Explorer is great, adding the mono section vibrato to the string section as well.

There are some bewildering flaws with the Solina String Synthesizer, which makes us think that the production schedule was rather tight when these were made:
The ARP Explorer Section seems to emit a ticking noise in certain filter modes (we've confirmed this with other owners of this instrument)
There are no separate outputs for the String and Mono section (WHY?!)
The mono synth always engages the highest note when you play a chord, whereas on many of the Italian counterparts you can 'prioritise': choose if the Mono section will engage the highest or the lowest note in a chord."
