'72 FARFISA COMPACT DUO PROFESSIONAL 252 COMBO ORGAN

Note: Auction links are affiliate links for which the site may be compensated.
via this auction

" For your consideration is this vintage 1972 Farfisa Compact Professional Duo organ. This particular example, serial number 6125/247, is in nice original condition and includes the original matching bass pedals, the original matching bench, and the original vinyl carrying bags. This incredibly intact original set has been thoroughly used and enjoyed throughout its previous ownership, but also displays significant evidence of resultant modifications, and though the original set is intact, the keyboard itself is not...

As suggested, the keyboard has been extensively modified, with the addition of many small buttons and jacks. While the keyboard works, it does not work properly, is low output, and requires more than just a typical service. Due to the poor working condition, we are selling it as-is, in need of serious repair.

Essentially a double keyboard version of the incredible 222, the 252 produces identical sounds with numerous extras and a slalom pedal. Famously used by Pink Floyd, Tangerine Dream, Sly and the Family Stone, and Led Zepplin, the Farfisa Professional keyboard has contributed tremendously to some of most recognizable '70's music.

This '72 Farfisa Professiona Duo features: (2) manuals of 61 keys (C - C), 34 voices, independent volume and vibrato controls, and a 13-key bass pedal (C- C) with expression and slalom pedals. Voice Sections include: Flute Section, Clarinet/Sharp Section, Sustain Section (Celesta, Harpsichord, Kinura, Long), Percussion Section, and a lower manual section including a Flute, Horn, Clarinet, Strings, Piccolo and Sustain.

As pictured, the Farfisa was matched up with a vintage Wersi amp and speaker combo, however, they are not included."

Pittsburgh Modular Foundation 2.0 Analog Eurorack Modular Synthesizer

Note: Auction links are affiliate links for which the site may be compensated.
via this auction
The Foundation is a fully modular, eurorack, analog synthesizer. A patchable system styled after the great monosynths of the past with no hardwired signal path or fixed voice architecture to restrict creativity. Driven by two wide range analog oscillators the Foundation produces a huge, warm sound that can't be matched by digital or VST synths. All of the elements of a classic voltage controlled synthesizer are available as an open, patchable, modern synth.

The Foundation is a "complete voice". It contains all the modules needed to produce a wide variety of complex sounds such as monster analog bass, cutting leads, evolving pads, and short percussive hits. All of which can be controlled directly using the Foundations' 42 knobs and switches then played with any standard Midi controller. The Midi module included in the Foundation allows for monophonic / duophonic / and dual monophonic patching for maximum flexability. The Foundation is also fully compatable with Expert Sleepers Silent Way software plug-ins¹.

An unpatched Foundation offers a clean slate for sonic exploration and sound design. The open format of a modular synthesizer allows for greater control and a deeper understanding of synthesis. The Foundation is comprised of a heavy duty eurorack case and individual eurorack modules designed to work together and as part of a larger modular system. Modules within the Foundation can be rearranged easily or replaced as a system grows or individual needs change."

SERGE 2 Panel Paperface w/ psu

Note: Auction links are affiliate links for which the site may be compensated.
via this auction

"Here is a very rare, early, kit-built Serge. One panel has a dual Negative Slew module, two Programmer modules, and a triple Bi-Directional Router. The second panel includes a module labeled "Dual 7486" (a ring-mod or dual VCA or both?), Sequencer, Dual Processor, Envelope Generator, dual Positive Slew, and dual Negative Slew. The amazing thing about the slew modules is that they can be cycled for use as oscillators (audio or LFO) or triggered as envelopes--they are precursors to the infamous Serge DSG. The Envelope Generator can be used as a pulse-width-modulated oscillator. The Sequencer is a gate sequencer that can be used to clock the programmer to make a CV sequencer. These two panels can serve many purposes: 7 oscillators or LFOs or a bunch of simple envelope generators, or anything in between. They can easily be used as an instrument on their own or interfaced with other modular gear.

Everything works on these panels except the the top half of the Dual Processor, which won't pass signal. The pitches I was getting by cycling the Slews were sometimes unstable and quirky, but sounded good otherwise. The power supply gets pretty warm. I'm sure you've noticed that someone built these panels with 1/8" (3.5mm) jacks. Notice the switch between the two programmers; it switches between the two top rows of the Programmers, sending to the jack on its left. The ground wire on one of the panels doesn't have a solder lug, but it is still easy to attach that wire to the PSU. The pots may benefit from a cleaning, but all work.

Since this is a vintage kit-built synthesizer it is sold strictly as-is..."

BassBoy - overview


Published on Sep 27, 2012 by alexfox101

"BassBoy is a monophonic digital MIDI controlled bass synthesizer. Device receives all information via MIDI input. The unit consists of oscillator which generates SAW & SQUARE WAVE using 16-bit band-limited wavetables, thus making the number of harmonics limited. After that, the signal itself goes through a simple implementation of MOOG filter, whose frequency range is chosen by MIDI commands and which is affected by the level of the envelope. The filtered signal then comes to the controlled amplifier, which creates the signal shape, and in the end through DAC (WM8762) and pre-amp circuit goes to the audio jack 6.35mm.

Raspberry Pi UI Update

via the Raspberry Pi Blog
(see the before pic here)
"I think this is done, and the design exposes enough underlying modulation flexibility to get lots of interesting sounds out of it. Now I need to tweak the code to represent all the new LEDs and tweak the existing LED positions in the overlay geometry to align with the rendered underlay. Should be done before the end of Saturday, tomorrow I'm on other stuff.

Note the VCA block, 'EG2=>A' and 'EG2=>B' - this is to allow stealing of the noise EG (EG2) to allow each oscillator to ramp independently. Both OSCs (in fact everything) is still envelope shaped by EG3 right st the end of the signal chain, but earlier on during modulation EG2 can now be applied to one of the OSCs. This could give some really interesting richness if a more harmonic-rich wave is ramped up slightly more slowly than the other, harmonic-poor wave, to add yet more movement to the attack. Experimenting with this by pulling on the OSCB slider while hitting notes leads me to believe that this could be a killer feature.

Here's an interesting observation for those who can count - notice that every modulation template (the stuff enclosed by blue lines on the right) has 16 options - 2x2x4 or 4x4. So every template is just one of 16 possibilities, 7 templates (VCA, phase, pitch, filter, LFO0, LFO1, MOD/CHANPR) so just 7 switch statements and a tiny burst of multiply-accumulates and I'm done. So the new modulation matrix code should be way, way quicker than the old one. I just need to write it ..."

New Phonec VST Funk Audio Demo

Phonec VST Funk by ramjetproductions

"Audio demo of new VST software synth from Psychic Modulation.

7 instances of the synthesiser in track with no added effects on bass, chords, pads or stabs. Drums from Cubase Groove Agent and Reel People v 3 drum samples. Real guitar by me. All synths played with Roland Midi Guitar GI-20 interface. www.ramjetproductions.co.uk"

"Phonec is best described as an 'analog flux synthesizer'. Inspired by the mystique of video logo synth scores from worn out VHS tapes, Phonec was primarily designed with character in mind. However Phonec is capable of producing a wide range of sounds such as vintage analogue tones, lo-fi synthscapes, ethereal pads, minimal techno sequences, and synthwave leads and basses. Phonec has an intuitive GUI that attempts to strike a balance between form and function, making it a very usable tool that can be a real inspiration to work with. Apart from it's unique character and smooth workflow, Phonec has several interesting features that set it apart from the crowd. Here is a brief overview that highlights the most important aspects:

Dual oscillators that can be combined in various ways
Analog style oscillator drifting
A unique Melt feature that adds instant character to any patch
Arpeggiator
Accent Sequencer
3 LFOs (2 monophonic, 1 polyphonic)
HFO (High Frequency Oscillator)
2 Modulation Envelopes
Echoshifter Delay Unit
Universal Value Display
Double Click Parameter Reset

Logan string melody meets the elkorus


Published on Sep 27, 2012 by wutierson

"This day, the Logan string machine visits Wutierson studio and it's imposible to don't do experiments with an elkorus.
The different types of chorus available at the Logan are very useful. It makes more versatile to process.
Tweaking the elkorus parameters + the Logan chorus I can make even more deep and lush chorus... ensemble of ensemble! a six line chorus! : )
No more effects are present, it's just Logan + elkorus v3"

"Keyboard electronic musical instrument "Maestro" is a portable polyphonic four-voiced analog\digital hybrid synthesizer with microprocessor control (KR-580) & programmed timbres "presets". Number of presets - 20. There is possibility to get vibrato frequency with depth & frequency control. This instrument includes "chorus" effect with depth control, filter with cut-off frequency & resonance control. There are also "arpeggio-tremolo" arrangement with speed control and joystick that pitch shifts & vibrato depth controls. It is the first soviet synth with microprocessor inside. Maestro synthesizer was produced in 80s on Kachkanar military radio plant on the same factory where well known Polivoks synth was produced. Synth has nice compact design. Some waveforms feed to analog filter with resonance. Arpeggiator has memory of key's order. The synth is polyphonic, you can play 4 voices at one time. LFO can modulate pitch by triangle waveform. There are controls of modulation speed and amount of pitch modulation. The synth is very rare! Due to it`s original architecture can produce very interesting sounds that can be used in any kind of music (check the Demo section). Comes with a full factory set in perfect mint condition!"

Protototype Polymoog Polypreset Surfaces

Note: Auction links are affiliate links for which the site may be compensated. The prototype Polymoog featured in this previous post is now up for auction here

"The auction is for an, are you ready for this? An early Moog, Polymoog, prototype. Likely the only one known to exist. It is named the Polypreset. Likely an early version of the Polymoog keyboard, the 280a. It is a killer piece. Filled with breadboards and point to point wiring. Fundamentally quite different than the 280A. In its current state it does not power up. The power supply is bad. But when hooked up to another power supply it comes to life. As you see in one of the pics. I have the secondary power supply hooked up. If you looks closely at the pics. You can see some of the LED's glowing. I do not think the current power supply is completely shot. As the piece does emit a hum from an amp when it is hooked up. I just think it needs cap work. I did not want to change any parts, in this piece of history. As for what works and what doesn't. I got 4 of the voices to work. And about two thirds of the keys. The middle section of keys. Does not work. Likely and issue with power to the center motherboard. Either way. This piece represents a time in the development of the Polymoog. And any Moog thereafter. It was hand built. It has a label on the back. Property of Marianne Marchese. Wife of the late Anthony Marchese. Who was head engineer at Moog through many a project. This Moog was found with a large lot of Moog gear. Which I will be listing as I go through it. If you are a fan of Moog gear from this era. You should check my auctions in the future..."
