Roland Ready GC-10 Guitar Synthesizer

via this auction
"hard-to-find Roland GC-10 dedicated 13-pin guitar synthesizer controller. I cannot recall the first time I saw the Roland GC-10, but I am pretty sure it was from looking at a Japanese web site. As far as I have been able to determine, the Roland GC-10 was briefly sold with the Roland GI-10 in the early nineties, primarily in Japan. The guitar was never offered for sale in the United States, nor can I find any reference to the Roland GC-10 in any Roland English-language literature. There is badging at the top of the headstock that reads "GTM." I saw a web page that called this the Roland "Guitar-to-MIDI" controller. I have seen one other guitar with the badging, and it is the guitar played on the Roland VG-99 demo page, though it is a different guitar."

Studio Electronics SE-1

via this auction
"Manufacturer Info:
The SE-1 is an analog, monophonic synth-module designed to re-create that classic Moog sound perfect for Hip Hop, R&B and Dance music. The classic Moog sound comes from its distinctive 24 dB lowpass voltage controlled analog filter. There is also a 12 dB low-/band-pass filter which emulates the classic sounds of Oberheim synthesizers.

The SE-1 uses three discrete voltage controlled analog oscillators for genuine analog synth sounds. And that's three VCO's, just like the Minimoog. They offer the basic waveforms you would expect from any analog: triangle, sawtooth, reverse sawtooth, square, noise, and random. There are also 4 multi-stage ADSR envelope generators used to shape your sound, the filter and more. Also available are Ring Modulation and Glide/Auto-Glide effects."

The Purple Synthesizers.com Modular

via this auction

"In September 2002, Roger Arrick of Synthesizers.com produced a one of a kind purple faced version of his modular synth. Normally, these modules are black. It is housed in a custom QCP22 22-Space Portable Cabinet which is also sporting a nice grey tolex covering, another unique feature. The modules also have blue LED's instead of the standard red ones. Synthesizers.com has never produced any modules in any other color than black, and this particular synth was produced as a one-of-a-kind item by them.

This modular synth is pure analog heaven. It has three oscillators and two filters. One filter is a "Moog" type transistor ladder filter switchable 12 or 24dB/octave. The other filter is a "State Variable" filter. This modular is similar in capability to a MiniMoog but with an extra filter, full patchability and other things like a "Clipper" and a Sample & Hold module.

This synth can be controlled by either Midi (via its own Q104 Midi Interface module) or any external Control Voltage (CV) device using the 1V/octave CV standard. Since this is a true modular synth there is no internal patching, like in an ARP 2600, so you will need patch cables to make sounds. The only patching internally is for powering the modules from the internal power supply.

After its initial manufacture, the first owner of this synth was Joe "Guido" Welsh. It was housed at his private studio, Guidotoons located outside of Nashville. Joe then sold the item to John LeVasseur, who used it extensively for his ambient progressive rock project Airfoil. John is the person offering this item for auction. (Hi!) This is the complete provenance of this item.

Examples of music (and additional images) made on this actual synth up for auction can be found at the owners MySpace music page at http://www.myspace.com/airfoilband.

The following effects can be used by player: tonecorrector, flanger, chorus, solo, rhythm.

Controls:
General
* amplifier (ON)
* output (effect, scale)
* trigger (ON)
* indicators - control, overload, effect.

Tonecorrector:
* level
* tone (1,2.3)

Flanger:
* range
* brightness
* rate
* width

Chorus:
* frequency
* detuning

Solo:
* spectrum
* rocktone
* suboctave

Rhythm:
* guitar

Rubber pedal controls - tonecorrector, flanger, chorus, rhythm/solo, effect.
Supply - in, out (transit, amplifier, phones).

JOHN BOWEN SOLARIS SYNTHESIZER PROTOTYPE DEMO NUMBER THREE

JOHN BOWEN SOLARIS SYNTHESIZER PROTOTYPE DEMO NUMBER THREE from RED MARTIAN on Vimeo.

"This features percussion sampled off of the Solaris using an MPC-1000. I did not alter those sounds to try to leave them as pure as possible. The flanging/phase shifting is actually the excellent Comb filter on the Solaris itself."

JOHN BOWEN SOLARIS SYNTHESIZER PROTOTYPE DEMO NUMBER FOUR

JOHN BOWEN SOLARIS SYNTHESIZER PROTOTYPE DEMO NUMBER FOUR from RED MARTIAN on Vimeo.

"The opening of this demo is John's own original demo that he did for the Prophet-5 in 1978. This tune uses the same Solaris generated drum kit from number three as well as more use of that excellent Comb Filter as well as Vector Synthesis using a realization of one of the Prophet VS factory patches."

JOHN BOWEN SOLARIS SYNTHESIZER PROTOTYPE DEMO NUMBER TWO

JOHN BOWEN SOLARIS SYNTHESIZER PROTOTYPE DEMO NUMBER TWO from RED MARTIAN on Vimeo.

"This is the second 'All Solaris' demonstration made up of 5 separate tracks sequenced and played manually. The pseudo Deep Note was done using two virtual CEM VCOs with about 5-6 seconds of exponential glide and a virtual SSM filter. The long resonant filter sweeping is done on the SSM model."
