Live annotated eurorack emotional cinematic synthwave, ARP-2600, Moog, OB-6 Tangerine Dream inspired

video upload by EthanJamesMusic

"This is a live cinematic synthwave electronic music performance inspired by later Tangerine Dream music, where I wanted to setup a more meditative environment and create a slow musical progression by interweaving layers with the Eurorack, using the electric bass as a guitar type of instrument, providing bass from the Moog Grandmother, chords from the DSI OB-6, and texture from the ARP-2600, and more texture from the Buchla 208c Easel Command. This is an entirely live and unrehearsed improvised performance, and I included annotations to show some of what I'm thinking about and also to demonstrate the different musical themes weaving in and out of the texture Since I'm a film composer by trade, this came out relatively cinematic and would work in certain movie score settings. This is a very simple setup to make a big sound. I hope this is educational for you as well, in terms of how I put these performances together. Hopefully this camera angle also helps you learn something!

Patch Notes:
Eurorack:
Stillson Hammer running at x6 multiply but using 1:1 gate from 0-ctrl to make bass. Two envelopes, one to VCA, one to filter.
Tempi clock divider running two channels of Make Noise René. First channel is to Dixie II oscillator to Jove filter to Erberverb. Second is to Serge NTO to Serge VQVCF to Echophon. I'm using a x4 clock divider to the Y channel, which is 1:1 to the VCA gate, but I'm using the C channel gate to the filter, which creates an interesting rhythm.

Moog Grandmother:
Normalled patch

ARP-2600:
3 oscillators tuned in octaves.

DFAM:
Pitch to Noise volume to create snare.

OB-6:
Polysaw chord setting"

"A very rare synth module produced in 1975.

Was basically the modular, educational version of the arp 2600. This module is the noise source offering both white and pink noise. The module runs using two 9vdc rectangular batteries. The outputs are mini jack euro rack sized

This unit would work nicely as an expander for anyone who owns an arp 2600."

Help Fund the The Alan R. Pearlman Foundation & Support a Trip to NAMM

Published on Nov 18, 2019 Alan R. Pearlman Foundation


It looks like we have another foundation dedicated to one of the greats of synthesizer history. The Alan R. Pearlman Foundation is currently seeking funding for a trip to NAMM on Indiegogo. Above is a video from Alan R. Pearlman's daughter Dina Pearlman.

"About the Alan R. Pearlman Foundation & ARPchives

My name is Dina Pearlman. I'm the daughter of the late Alan R. Pearlman, inventor of ARP Synthesizers - groundbreaking electronic synthesizers that changed the face of music forever.

Why It's Important

Since the death of my father in early January, I have seen overwhelming evidence that there needs to be a thoroughly reexamined history of his work because his story and that of ARP Synthesizers is relevant to the history and understanding of modern music.

Even more importantly, because of the high cost of education and vintage electronic music instruments, we want to offer opportunities for musicians, particularly young and underfunded musicians to have educational and artistic opportunities - something that Alan was passionate about.

This is why the Alan R. Pearlman Foundation was formed - to honor his legacy as an inventor, a musician, an entrepreneur, an engineer and a mentor... to make his innovative inventions publicly accessible, and help inspire future generations to imagine and create through charitable projects.

Getting Started

Before we can start our projects, we need to get the word out about our Foundation and our Mission.

We have been given an opportunity to introduce the Foundation to the music instrument industry at the hugely popular NAMM (National Association of Music Merchants) show this January. This is a once-in-a-lifetime opportunity for us. At NAMM, the foundation board members will promote the Foundation, its mission and its charitable projects to electronic musicians, engineers, potential donors and the press.


How You Can Make a Difference

As the Foundation is in its infancy, we are seeking funding to cover some of our costs of attending the show: that includes tradeshow booth expenses, marketing materials, and travel expenses for three of our board members. We need help from people like you! Music lovers, synth lovers, creators and believers in perpetuating educational and creative opportunities. As the Foundation is still applying for 501(c)(3) status, we cannot guarantee a tax-deductible contribution.* However, we can offer some fabulous incentives!"

ARP-2600, Moog Grandmother live cinematic Tangerine Dream inspired synthwave annotated performance

video upload by EthanJamesMusic

"I wanted to do a live synthwave performance with annotations that show what I'm thinking as I create these. Almost everything on my channel is an improvisation, so I'm thinking on both music theory and technical levels at all times. This starts with static arpeggios and utilizes modal shifting to create the chord progressions. I'm using a fairly simple setup of just the Moog Grandmother and the ARP-2600, so that the text can follow the music. The arpeggios are inspired by new Tangerine Dream electronic music. Since I'm a film composer by trade, this came out relatively cinematic and would work in certain movie score settings. I hope this is educational for you as well, in terms of how I put these performances together."

"This video demonstrates the sound of the Electronic Dream Plant WASP synthesizer, Kim Wilde used it for her hit single Kids In America, and Duran Duran keyboard player Nick Rhodes used it early in with the band.

Sadly Chris Huggett passed away on October 22nd 2020 but leaves behind a legacy of synth production that in a British way rivals that of Moog, Oberheim, ARP, and other synthesizer manufacturers. Today there are companies who recognise the popularity of the EDP WASP and have cloned them, Behringer and the Jasper are just two who have released their version of this classic vintage sounding synthesizer which rivals some Moog, Oberheim, ARP, Yamaha, and other famous synthesizer company products since the late 1970's.

Bob Moog Fondation 2022 - 2023 18 Month Calendar

via Signal Sounds, available here

The Bob Moog Fondation is a charitable organisation, based in Anaheim, North Carolina, just a few streets away from the current Moog factory. It acts both as a archive for Bob's work over the years, a museum to show the timeline of his inventions (and more general synth developement) and an educational resource for schools providing hands on experience for children and adults.

Imgaine you had to do all those things? It's pretty certain you'd quickly lose track of what day it is, what week it is or even what month it is (signs of recognition and enthusiastic ndoding from fellow COVID brain fog peepz at the back of the crowd)?

What you would need in that case is.....a calendar! Obviously you can get calendars with amazing inspritation quotes, beautifull sunsets and cute animals but what if you could get an unbelievalbe nerdy synth related calander featuring 18 of the world's most influential synth designers? That would be pretty freakin' cool, no?

"We are proud to announce the release of our epic 2022 Synthesizer Pioneers 18-month calendar, which honors 18 innovators in the field of synthesis from the past 60 years. This is the fifth calendar released by the Foundation focusing on the rich history of Bob Moog’s legacy and the web of innovation in synthesis to which he was connected.

This calendar is the first to bring to the fore the historic achievements of synthesizer pioneers from all over the world. It features:

Harry Olsen and Herbert Belar (RCA)
Harald Bode
Raymond Scott
Bob Moog
Don Buchla
Peter Zinovieff (EMS)
Alan R. Pearlman (ARP)
Ikutaro Kakehashi (Roland)
Fumio Mieda (KORG)
Tom Oberheim
Dave Smith
Roger Linn
Wolfgang Palm (PPG)
Dave Rossum
Peter Vogel and Kim Ryrie (Fairlight)
Ray Kurzweil
Felix Visser (Synton)
Makoto Fukuda (Casio)
Many of the pioneers have contributed historic photos of themselves, with their hallmark inventions from their private archives. Also included within the calendar are scores of dates of particular historic importance provided by the pioneers. A brief narrative is included with each photo.

The 18-month calendar also weaves together connections between Bob Moog and many of the featured pioneers. His relationships with them ranged from inspiration to friends to colleagues to business associates. Secondary photos on many of the pages highlight that connection, showing Bob with his fellow pioneers.

The 18-month calendar is printed on #80 stock paper, making the images suitable for framing after the year is over!

This is the first time any of the Moog Foundation's products have been availabe outside of the USA so we're pretty happy to be able to bring it to you, and a portion of the profits are re-invested in the Bob Moog Foundation so it's a win/win situation.

The calander runs from Jan 2022 until May 2023 (and before you ask, we have no idea why it's an 18 month calendar...maybe they're just relaly indecisive and couldn't cut the list of synth pioneers down from 18 to 12?) and is available right now, right here.

"Rare to find an EML 101 in such good condition, they were often owned by educational institutions and were commonly played hard by students. This ElectroComp 101 was used for 18 years in a sound design studio in Hollywood and has been sampled/played extensively on many film soundtracks and TV commercials. A real workhorse that is often described as a poor-man's Arp 2600 but that's not really fair; it has a very unique sound that some describe as harsh, metallic, alien, machine-like, I think this comes from the fact that it has no onboard dynamics and really responds well to reverb, delay and other sweeteners."

"Text from the back cover:

SYNTH GEMS 1 is your guide to an eclectic and amazing collection of synthesizers as art. Experience the history, technology, and sonic innovation of electronic music in a completely new way.

With their widely diverse designs and intentions, synthesizers offer a world of fascination. What thoughts and emotions guided their creators? What do they say about the era when they were created? How do their form and function define one another, and the music they make?

As much for serious synth enthusiasts as for newcomers to electronic music, SYNTH GEMS 1 is an enlightening look into this wonderful world of vintage synthesizers.

An art gallery of electronic aesthetics

SYNTH GEMS 1 takes you on a tour of over 60 remarkable keyboards — large and small, famed and rare, elegant, beautiful, and brutal… and ranging from classics that define entire genres to rare oddities that bring their own grace to the world.

Each synthesizer is presented in a series of finely detailed photographs, with a discussion of its origins and importance. From the dawn of commercial synthesis to the close of the Twentieth Century, the lives and times of these unique instruments are chronicled in exquisite pictures and thoughtful stories – mingling music, technology, commerce, and visual art.

Meet the synthesizer

Besides a brief introduction to the basic elements of synthesizer design, as well as a comprehensive Glossary, the book is rounded out by tours of the three museums that opened their collections to be photographed, and a selection of resources for further study: books, films, educational initiatives, online resources – even ways to play with these sounds at home.

Known classics and significant rarities

Bob Moog Foundation Announces impOSCar2 Controller Raffle Touch Digital Controllers™ and GForce Software Unite in Tribute to Moog Legacy

"ASHEVILLE, N.C. – September 19, 2011 – A raffle to benefit the Bob Moog Foundation begins today. Two lucky winners will each receive the new impOSCar2 Controller from Touch Digital Controllers and an entire suite of five virtual instruments from GForce software—a prize package valued at nearly $2,500. The raffle will continue until all 500 tickets have been sold. Because the BMF will be awarding two complete packages, each entry has a 1 in 250 chance of winning. Tickets are $20 each, or you can improve your odds by buying six for $100.

Raffle tickets are available from the Bob Moog Foundation’s Web store. Be sure to enter before all 500 tickets have sold out. Two winners chosen by a random-number generator will be announced once all 500 tickets are sold. The winner will be announced within 24 hours after that time. Raffle participants should check the Foundation’s website and social media outlets to learn when all 500 tickets have been sold and who the two winners are. The winners will be contacted by email.

The new impOSCar2 Controller provides a physical user interface for both the standalone and plug-in versions of GForce Software’s acclaimed impOSCar2 soft synth. The combination of software and hardware offers the sound and functionality of one of the most sought-after analog/digital hybrid synthesizers ever made—Oxford Synthesizer Company’s OSCar—brought up to date with automation, effects, 16-note polyphony, and tons of patch storage.

As a tribute to the memory of Bob Moog, Touch Digital Controllers donated not one, but two impOSCar2 Controllers to the BMF. One is produced in a hand-finished natural mahogany and the other in ebony black on oak. These beautifully made controllers deliver plenty of visual and tactile feedback to make programming impOSCar2 a pleasure, just like programming the original OSCar but with total recall. With 101 high-resolution knobs and buttons, every parameter is available from the controller’s front panel to remotely operate the software. In addition to its dedicated impOSCar functionality, the controller can be configured to control any software instrument that supports MIDI Learn.

“The impOSCar2 Controller is our first product, and we are proud of what we have been able to achieve with this handcrafted music instrument,” said Richard Lawson and Kent Spong of Touch Digital Controllers. “As synthesists, and as a manufacturer, we have been deeply inspired by the one man who pioneered the whole thing: Bob Moog.”

Released in July, GForce’s impOSCar2 breathes new life into the popular previous version, first launched in 2004. New features include more comprehensive modulation routing, an improved arpeggiator, ring modulation, panning mono and poly unison modes, and more than 1,000 signature patches. Add nine filter types, six portamento modes, and a programmable additive synthesis grid, and you have one powerful soft synth.

Want more? The BMF’s raffle winner will also receive licenses for M-Tron Pro, Minimonsta, Oddity, and Virtual String Machine, which realistically emulate the Mellotron, Minimoog, ARP Odyssey, and numerous polyphonic string synthesizers, while adding dozens of innovative touches. In addition, GForce Software has included the ChamberTron and OptiTron Expansion Packs for M-Tron Pro.

BMF Executive Director Michelle Moog-Koussa said, “Through the ImpOSCar2 Controller, Richard and Kent bring their love of vintage synthesizers into the design and ethos of this very special piece of handcrafted hardware. Bob’s goal was always to give musicians the highest level of expressivity, and his interface design was a big part of that. The construction of the ImpOSCar2 Controller echoes that commitment to musicians. Our many thanks to Richard, Kent, and the team at GForce Software for sharing their life's work with us. Their support is a tribute to Bob Moog's legacy and to the work of the Bob Moog Foundation.”

The Bob Moog Foundation (www.moogfoundation.org) honors the legacy of synthesizer pioneer Dr. Bob Moog through its mission of igniting the innovative and creative spirit at the intersection of music, science, and history. Its projects include Dr. Bob's SoundSchool, which brings electronic musical instruments into the schools to teach children science through music; the Archive Preservation Initiative, an effort to preserve and protect the inventor's extensive and historic archive; and the future Moogseum, an innovative educational, historic, and cultural facility that will bring Bob Moog's spirit alive to ignite innovation and creativity in children and adults. It will be located in Asheville, N.C., in the years ahead, pending necessary funding. The Bob Moog Foundation is an independent, donor-driven 501(c)(3) non-profit organization and is not formally affiliated with Moog Music, Inc."
