"Sequential Circuits - Split Eight - vintage 1984 analogue synthesizer. Just had this fully serviced by a pro audio technician, everything is working perfect. Battery was just replace along with calibrating. It's like owning a new synth but it's vintage!!"

This has the same synth engine as the Six-Trak, Multi-Trak, and Max.

Analogue Solutions Leipzig-S

"Analogue Solutions Leipzig-S Analogue Synthesizer and Step Sequencer - as new and hardly used. Comes complete with box, manual, power supply and 11 months manufacturers warranty. Sounds fantastic, but I simply have too many analogue monosynths already, so it has to go.

KEY FEATURES OF LEIPZIG-S

Pure analogue voice and modulation circuitry.
Fat Moog style transistor ladder filter.
2 VCOs with Glide and Sub-VCOs.
Osc Sync & Cross-Mod
Plenty of modulation routing possibilities.
We are a big fan of electronic percussion here, so Leipzig-S modulation choices provide for good drum possibilities
Analogue step sequencer – with plenty of clocking options.
Audio input so can be used as a sound processor.
Rugged steel/aluminium construction.
MIDI In for software sequencer control.

This synth has NO memories! - Advantages;

None of the parameters or controls are quantised. So when you turn a knob, you are turning a resistor that affects a real analogue circuits.
Because each parameter is not under solid CPU control, each parameter has that tiny analogue drift that adds so much to character.
You are forces to be creative. No reliance on presets! Each time you make a sound you are being original.
Quick, easy and simple to use! WYSIWYG - no nasty menus and sub-menus to change the sound.

Differences between Leipzig-S/SK and the original Leipzig;

Envelopes are now full ADSR

EGs can be disconnected from MIDI trigger

VCO2 can be disconnected from MIDI (free running modulator!)

Analogue step sequencer

VCF can be modulated from either EG1 or EG2"

Electro-Harmonix HOG Octave Generator Synthesizer Guitar Effect

I was going to pop this one up on MATRIXSYNTH-BB, but figured it was an interesting reminder of what else is out there in the synth world. Electro Harmonix pedals tend to cross over to the synth realm not only with their dedicated synth pedals like the HOG, but others as well. See the EHX label at the bottom of this post and scroll through posts for more.

"Generate everything from extreme sub bass to powerful multi-octave chords with this harmonic octave generator!

Blast off to a whole new universe of sounds with the Electro-Harmonix HOG, a polyphonic guitar synthesizer with NO special pickup required. It gives you complete control of up to 10 interval pitches including fifth and third intervals, glistening filter sweeps, and insane pitch bends. Dedicated filtering and envelope control, with numerous setup options, make the HOG a must-have performance instrument.

The HOG can simultaneously generate multiple octaves and harmonics from your input signal. Whether you play single notes, arpeggios or full chords, the HOG will track every note you play. In addition, the HOG has seven expression modes that enable you to modify your sounds using the included expression pedal, a MIDI controller, or the expression button on the HOG itself. There is also an amplitude envelope and a 2nd order low-pass filter with resonance. The optional EH Foot Controller (I am listing separately) allows you to store and load six presets.

You have control over the HOG's basic audio circuitry with an input gain slider (with clip LED), a dry output slider, and a bypass switch. Audio I/O includes 1/4" Hi-Z input, 1/4" output, and a buffered direct output jack. The voice controls let you access the polyphonic synthesizer section. There are 10 voice sliders on the HOG, each with a white cap with a black line that controls the output volume for its voice. The ten sliders let you generate notes two octaves down, one octave down, the incoming signal, a fifth up, one octave up, an octave up plus a fifth, two octaves up, two octaves up plus a third, three octaves up, and four octaves up. The selectable envelope section controls the amplitude attack or decay of the voices, with separate sliders for the lower five voices and upper five voices.

The Spectral Gate button activates circuitry that emphasizes the loudest frequency or harmonic and reduces the volumes of all other present frequencies and harmonics. The filter frequency slider controls the cutoff or peak frequency of the low pass filter, while the filter resonance slider controls the Q or peak of the filter.

The HOG's seven different expression modes are selected consecutively by the expression mode switch: bend one octave, bend one step, volume, freeze plus gliss, freeze plus volume, wah-wah, and a filter. There is also an expression reverse mode and you can control the expression modes externally with an expression pedal or modulate any of the expression modes using MIDI pitch bend.

PPG EVU Expansion Voice Unit 80's wavetable synth by Wolfgang Palm

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

"This is the "brains" of a PPG Wave 2.3: Classic vintage 8 voice wavetable synth; digital oscillators for complex waveforms; warmed up with rich analog filters [8x Curtis SSM 2044 VCF chips], designed by Wolfgang Palm, used by famously by David Bowie, The Fixx, Trevor Horn, Jean Michel Jarre, Art of Noise, Rush, Depeche Mode, Gary Numan, Robert Palmer, Psychadelic Furs, Talk Talk, The Cars, Ultravox, Steve Winwood, Rush, Stevie Nicks, Thomas Dolby, Pet Shop Boys, Mike and the Mechanics, and Stevie Wonder.

However the buyer should know:

This unit predates MIDI [was built between 1982-1984] and will require a technician to complete the build we started for the MIDI to EVU converter, as planned here: http://www.hermannseib.com/english/synths/ppg/midiretro.htm

All of the parts, veroboard circuit, and new OS ROMs are included."

Update via Rich in the comments: "Just a short note of clarification:
The above mentioned Curtis SSM2044 was a combination of 2 different companies:

Curtis Electromusic Specialties, founded by Doug Curtis - made the CEM3340 VCO, (Roland Jupiter 6 and others if I recall correctly), CEM3320 VCF, CEM3310 ADSR and quite a few others.

Their biggest competitor was Solid State Microtechnologies by solid state music who made the infamous SSM2040 4 cell chip that was used for 4 pole Low Pass Filters, 2 pole State Variable Filters and a few other configurations. (Prophet 5 versions 1 and 2. Version 3's used the thinner sounding Curtis CEM3320.)
The Korg Mono/Poly and Polysix (amoung many other units) used the SSM2044 4 pole Low Pass Filter."

"This has a very clear sound for an analogue vocoder, a big part of why it makes voices so intelligible is the syllable function which inserts noise bursts into the signal for “s” and “sh” syllables. This is a pretty rare feature on an analogue vocoder, and it really helps with intelligiblity. The syllable function is also really cool for creating rhythms.

Here’s some info on it pulled of the interwebs [appears to be via Analogue.org]:

The Voice Spectra has good reputations in Japan for clear extent, high timbre, and for Speech Tracking Function (STF). STF is basically a pitch- to-voltage converter which functions by reading the glottal pulses of the speech signal. The control voltages from the output of the pitch extractor are fed to the VCO, so that this follow the cadences of the speech signaI. STF is an interesting additional facilities only to be found on more expensive vocoders like EMS.

Everyone familiar with vocoding will appreciate the Voice spectras compressor and Voiced/Unvoiced detector*.

The Voice spectra is a high quality studio-vocoder, appreciated by the staff at music studios, professional musicians, etc. in Japan. The articulation of the output signal is extremely good, being distinguished by remarkable clarity and distinctiveness. This quality of articulation, among other things, is what distinguishes SKY soundlab from other less sophisticated vocoders like the MAM VF11. The Voice spectra comes with an inbuilt power supply as well.

*If the air from the lungs is not forced through the vocal chords, but simply expelled through the mouth, then so ralled UNVOICED sounds are produced, such as `f' or `h'. These are basically similar to the type of sounds which can be produced by a noise generator. Most excitation signals do not have a sufficiently wide dynamic spectrum to synthesise the sound of sibilants (`s', `h', etc.). For this reason the voiced/unvoiced detector ensures that the noise generator provides the synthesiser section with the appropriate `raw material' whenever the excitation signal cannot do so.

The voice can be seen as a complex sound generating instrument, consisting of a frequency and amplitude-controlled oscillator (the vocal chords and lungs), a noise generator (the lungs) and a set of tone filters (the mouth and nasal cavities).

So, regarding Seekers, some of you might remember this beauty. See the Seekers label below for more. There was a real Seekers manufacturer that made this vocoder and then there was Elhardt.

"for sale on ebay"

Note this demo doesn't do the best job demoing the synth, but it's purpose of course is to show it is working. The Fizmo is a Transwave synthesizer which was Ensoniqs implementation of Wavetable Synthesis. When it was released Virtual Analog synthesis was all the rage and people were disappointed with the Fizmo because although it was knob laden like the new hardware VAs, it definitely was not a VA synth. It excels in digital morphing sounds and that is a good thing. It is a unique synth and sonically, always reminded me as sitting somewhere between the Waldorf uWave/XT series and a Hartmann Neuron. The Neuron of course employed a whole different method of synthesis termed neuronal synthesis along with I beleive methods of re-synthesis.

"Up for sale is a used Ensoniq Fizmo Rack, and non-original nintendo gaming console power supply. There was an issue with the orginal power supplies damaging Fizmos, so I never used the supply that came with it."

I heard changing the power supply actually doesn't solve the problem. See The Fizmo Fix on Carbon111's site for the hardware fix.

The auction also pointed to Fizmotropolis, what looks to be a great resource for the Fizmo. I haven't seen it before. I'll put a separate post on it next.
