Roland GR-300 Guitar Synth SN 232801 with Wayne Jones RC-1324-VR

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


via this auction
Note: I added a new Wayne Jones label to the site. New posts will get them. For older posts, click here.

You can find a video of the RC-1324-VR previously posted here.

"Here's a package deal that will get you playing a modern 13 pin guitar synthesizer controller with a vintage Roland GR-300 Guitar Synthesizer module.

** This system is not recommended for use with GODIN 13 pin guitars ** See below for more information.

The winning bidder will receive the following:

1) One of Roland GR-300 Synthesizer Module with upgraded capacitors and a DB25 pin input. Unit tested by none other than Wayne Joness in January 2013.

2) One of RC-1324-VR 13 to DB25 pin converter. Built by Wayne Joness in January 2013 for myself.

3) One of DB25 pin cable to connect the RC-1324-VR to the GR-300

The overall condition of everything is excellent for the GR-300 and near mint for the RC-1324-VR. Everything is in proper working condition.

You can get more information on the RC-1324-VR at Wayne's site: http://www.joness.com/gr300/RC13.htm

Please Note: The GR-300's input has been changed from one that fits the traditional 24 pin cable to a DB25 style input, allowing for use of inexpensive and shielded replacement cables such as those made by Belkin, as opposed to the expensive and non-shielded proprietary Roland 24 pin cables. What this means though, is that if you plan to ALSO use this system with a viintage 24 pin guitar controller like a G-505 or G-202 etc...., you will either need to make a 24 pin to DB25 pin cable (Wayne can make you one....) or, you can modify and upgrade the controller itself to a DB25 pin output and solve your Roland cable issues forever.

The GR-300 unit was tested by Wayne Joness in January 2013. Here is what Wayne had to say:

'Hello Keith!

So...I am happy to report your GR-300 passed all the tests with flying colors.

I have removed the bottom panel, and I can tell you that your unit is a "version C" meaning the final revision of the circuit board. This is a good thing.

http://www.joness.com/gr300/GR-300.htm#version

I checked the power supply, and your unit does have the problematic blue tantalum capacitors in place:

http://www.joness.com/gr300/GR-300.htm#repairs

I did not mention this originally when you asked about sending me your unit, but I would like to propose that I replace the blue tantalum capacitors with modern electrolytic capacitors as outlined on the website. This will protect your GR-300 from future failures.'

I agreed to the capacitor upgrade of course! So the future owner has a fully bench tested AND upgraded/protected GR-300 to boot!"

Wandering (paper circuit as a ribbon controller)


Published on Oct 8, 2013 GruithuisenCityMan·463 videos

"Wandering (paper circuit as a ribbon controller)

Hello ! My name is Frederic Gerchambeau. I have made this movie and this music. The music has been made using a parper circuit and a Doepfer analog modular system.

The paper circuit has four outputs. One leads to the cutoff frequency of lowpass filter 1, another leads to the cutoff frequency of lowpass filter 2, a third one leads to the pitch CV control oscillator 1 and a fourth one leads to the pitch CV control oscillator 2. So, with a wire coming from a Doepfer A-183-2 offset, i can control these four parameters depending where the wire is on the paper circuit. The echo effect comes from a Make Noise Echophon. Enjoy !"

An Interview with Bruno Spoerri on Astronauta Pinguim

Update: in case you read this post when it first went up, be sure to give it another look for a few updates.  It's a bit convoluted with quite a few tangents, but that's how it goes sometimes.

Read the full interview on Astronauta Pinguim here.

The following are some excerpts and tie-ins to other bits of synth history.

-----

Initially a saxophone player, Bruno Spoerri explored electronic music in the 1960s on.

"In 1964 he was invited to a job in an advertising agency and began to work with electronic music using a Ondes Martenot and, after, using lots of synthesizers and also experimenting with electrified/synthesized saxophones..." "As a saxophonist and jazz improviser I always looked for ways to play without a keyboard."

Pictured above is Bruno with his EMS Synthi 100 (videos previously posted here and here).

On the Synthi 100: "I bought the Synthi 100 in 1971. In 1987 I gave it to Felix Visser (Synton) in exchange for a Fairlight CMI; some years he had to sell it at an auction, and I don't know where it is now (I would recognize the instrument, as I did some small changes on it)."  It was listed on Vemia back in 2009 posted here and here. Click though for pics.

In 1974, he recorded the album 'Iischalte (Switched-on Switzerland)'.

Bruno Spoerri on 'Hymn Of Taurus':
"The rhythm track was created with my very first primitive ring modulator (4 diodes and 2 transformers) that is why it is so dirty The voice went of course through the EMS vocoder, the choir was created through the VAKO Orchestron."

-----

Again, don't miss the full interview with Bruno Spoerri on Astronauta Pinguim here. There's some fascinating history there including Ginette Martenot and the Ondes Martenot, Oskar Sala with his Mixturtrautonium, and Joel Chadabe. Regarding his original gear, "most of my analog gear is sold (most of it to the remarkable Swiss Synthorama of Martin Hollinger), but I still have my first synthi, the EMS VCS-3 (from 1970), the ARP 2600 with sequencer and the Lyricon I and II. I use the lyricon quite often in performances, the other gear mostly for demonstrations to visitors."

I was fortunate enough to visit Synthorama back in 2008. You can find my pics and videos from the visit here. See the Synthorama label for other posts including a one of a kind modular, the Airböurne, created by the curator of the museum, Martin Hollinger.

"I just threw some of my small Reaktor weekend projects into one ensembe to see how it sounds like, you can hear and see the result in this video.

All the instruments in this ensemble are just ideas or prototypes or however you want to call it. Especially the "Circle Seq" thingy is a really basic idea I realized very quickly yesterday, I have quite a few cool ideas where to go with it though (Recursive modulation between the LFOs that run the sequencers should be fun for example!).

I'm doing nothing is this video by the way, all the instruments are entirely self running.

Sorry for the bad video quality, one day I'll learn how to use all this fancy video stuff."

via this auction

"Here's an excerpt from the manual:

The S1 is a semi-modular, analogue monophonic synthesizer. It is easy to get started with since it is prepatched for optimal use of its sound producing possibilities and eliminates the need for external connections between modules during use. Each module can be disconnected and used separately, e.g. to control or be
controlled by other instruments. This flexibility enables and simplifies experimentation with creation and reproduction of sound.

* Three oscillators with seven basic waveforms
* Ring modulator
* Noise generator with two three noise shapes
* Low pass filter with selectable 4 / 6 poles and quasi band pass mode
* Multi mode filter with selectable 2 to 6 poles and three modes
* Wide range envelope generators
* Master amplifier with build-in overdrive stage
* LFO with seven basic waveforms and wide rate range
* Extensive modulation of, virtually, all synthesis parameters
* Build-in MIDI to CV/gate converter with 16-bit resolution

Several parameters can be voltage controlled by external signals and, simultaneously, control external devices
by the build-in MIDI converters voltage outputs (see Rear Panel). The S1 is a stand alone instrument and the
possibility with patching and integrating it into an external modular (or semi-modular) synthesizer makes it
extremely flexible."

WMD Pro Output Headphone Amp & Output Module

Perfect Circuit Audio (RSS)

"Balanced professional grade outputs and high quality headphone driver!

The WMD Pro Output is a simple and purpose built module to get your modular signal interfaced with professional and consumer audio gear. It also includes a very high quality headphone driver.

Rail to rail opamps at the input stage allow for headroom above the typical eurorack levels of 20Vpp. The Pro Output can handle 23Vpp before clipping. Signals are attenuated down to the proper levels allowing for simple adjustment free connection to any type of device, professional or consumer.

The Pro Output is DC coupled through the entire signal path, including the headphone driver. This design eliminates coupling capacitors and the distortion they can cause.

Controls and I/O

Input - The inputs are designed to accept any normal modular level. 10Vpp is the nominal operation level. The left input is normaled to the right side for mono operation. Inputs will clip at 23Vpp, giving enough headroom for any eurorack signal.

Phones/Line - The headphone driver connects to a 3.5mm stereo jack, and a 1/4" jack for whatever type of headphones you use. It can drive both simultaneously.

The headphone output level is internally limited to protect against accidental knob turns. Connect a couple of jumpers to the rear of the module to disable this limiting. This will allow the headphone amp to drive headphones extremely loudly, but still without distortion. Output quality remains the same regardless of the jumper settings.

With the limiting enabled (jumpers off), the maximum output is around -10dBV. With limiting disabled (jumpers on), the maximum output increases to pro level, about +4dBu.

Stereo - The Stereo (-10dBV) output is designed to interface directly with consumer level gear. Hook directly to sound cards, portable recorders, and speakers. It can be used as a second headphone output but will be loud.

+4dBu Bal - These two outputs (left and right) are high quality low impedance balanced line drivers. They are designed to drive long cables and to drive balanced transformer or transformerless inputs. Use these to connect directly to mixing consoles, mic preamps, or any other piece of professional outboard gear.

Features

Perfect Circuit Audio (RSS)

"The VCOFan is VCO that uses a fan as a sounds source.

There is a LED under the fan that shines onto the blades of the fan, the fans bottom side is spray painted white, so the light from the led reflects from the blades. Next to the LED there is a LDR that translates the reflected light into a voltage, which is the audio signal.

Connections: The top connector is the CV input for the Fan speed (0v to 12v). The middle connector is the CV input for the LED brightness (0v to 12v). The output is the bottom connector, it is a audio signal that is capacitor coupled.

Potentiometers: The top potentiometer sets or attenuates the Fan speed. The middle potentiometer sets or attenuates the LED brightness. The bottom trimmer potentiometer (under the 2mm hole) sets the audio output volume.
