KOMA Elektronik Poltergeist: Stereophonic Demonstration

Published on Aug 4, 2016 KOMA Elektronik

"The KOMA Elektronik Poltergeist Quadraphonic Mixer / Panner / VCA can also function in stereophonic mode with a flip of a switch. With an array of eurorack modules and the Komplex Sequencer for example, the Poltergeist is able to throw sound from left to right and in between while functioning as a quad vca and mixer module."

KOMA Elektronik: Poltergeist Tutorial

Published on Apr 6, 2016 KOMA Elektronik

"In this video, we go through each feature of the Poltergeist Analog Quadraphonic Audio Mixer. From inputting a signal and controlling it with the VCA, panning around 360 degrees, solo and mute functions to stereo and quad modes, auxiliary inputs, slope control, and gain CV controls. The main synthesizer sound is a Malekko Anti-Oscillator through the KOMA Elektronik SVF201. The envelope is from a Doepfer module. The kick drum is courtesy of a Bastl Tea Kick followed by the Roland TR8. All synced and controlled by the Komplex Sequencer."

1. KOMA Elektronik Poltergeist Analog Quadraphonic Mixer Teaser

"Teaser video for the new KOMA Elektronik Poltergeist eurorack module. Analog quadraphonic sound recorded with a binaural microphone to illustrate quadraphonic sound best in stereo. The video starts off with the Bastl Tea Kick which is panned to all outputs with the field control. The bassline's panning is sequenced with the Komplex Sequencer. The noise hats come in and are sequenced via sample and hold. Lastly the pad is panned around from the Master Origin from a Intellijel Dixie sawtooth wave.

NOTE: Wear headphones to experience this video correctly. This is a binaural recording of the Poltergeist in a quadraphonic room to best display its capabilities in a stereo setting. Recorded with a Neumann KU-100 binaural mic courtesy of Bohemian Drips in a quadraphonic studio with Neumann KH-120 monitors at Noize Fabrik, Berlin.

2. KOMA Elektronik Poltergeist Example Patch: Crossover

"In this binaural stereo video, we illustrate the Poltergeist with the Crossover example patch from the manual. Input your synthesizer (Anti Oscillator to SVF-201 to Doepfer VCA/Doepfer ADSR) to one channel. Also take the pitch CV (which is sequenced from the Komplex Sequencer) to the Pan CV Input so the sound moves along with the melody. Komplex Sequencer Play Mode and Poltergeist Pan slope are changed throughout to evolve the patch.

Recorded with a Neumann KU-100 binaural mic courtesy of Bohemian Drips in a quadraphonic studio with Neumann KH-120 monitors at Noize Fabrik, Berlin."

3. KOMA Elektronik Poltergeist Example Patch: Dopplerganger

"In this binaural stereo video, the Poltergeist is employed to create two alternating doppler effects. With a pitched sound going through 2 channels, use a slow attack envelope (PEG here) and connect to the Master Origin. Now take a triggerable LFO (Pingable LFO) and connect it to the VCA of both channels as well as the pitch of the VCO. Match the attack time of the envelope to one period of the LFO. Now set the Pan pot of the first channel so the sound comes from Quadrant 3 to Quadrant 1. The second channel is set so the sound moves from Quadrant 4 to 2. You will hear the same sound coming towards you from the front and from the back alternating with each other."

4. KOMA Elektronik Poltergeist Example Patch: Bruce Bickford

"The Poltergeist Quadraphonic mixer in action with the Bruce Bickford patch as found in the manual. Recorded with binaural microphone to illustrate better quadraphonic sound in stereo. Patch your hi-hat sound (in this case Doepfer Noise through the SVF-201 into the Poltergeist VCA that is CVed by the Doepfer ADSR) into a channel. Take the trigger for your hihats also to clock a S&H module that is processing noise. Then take the CV from the S&H into the channel's Pan CV to move the hihats randomly around the quadraphonic field.

An Interview with Barry Schrader

Hi everyone! As you know Barry Schrader will be giving his farewell concert at CalArts on September 26. The following is the beginning of my interview with him. I opted to post the questions and answers as they come in.  New QAs will get a new post so you do not miss them and they will be added to this post so we have one central post for the full interview. This should make it easier for all of us to consume in our busy lives, and it will allow you to send in any questions that may come to mind during the interview process.  If you have anything you'd like to ask Barry, feel free to send it in to matrixsynth@gmail.com.  This is a rare opportunity for us to get insight on a significant bit of synthesizer history, specifically with early Buchla systems, and I'd like to thank Barry for this opportunity. Thank you Barry!

Barry Schrader CalArts Farewell Concert Set for Saturday, September 26

Broadcast live streaming video on Ustream
Update: live stream from ROD Webcast added above. Interview with Barry here.

Barry Schrader, one of the founders of the early electronic music scene at CalArts School of Music is retiring after 45 years. Many of you will remember him from previous posts here on MATRIXSYNTH. Here he is with a Buchla 500 in CalArts' studio B-304, along with Morton Subotnick and John Payne. If you are in the area, you do not want to miss this event. This is a chance to see one of the founders of our scene perform live. For those not in the area, the concert will be available on the live ROD Webcast. I hope to have an extensive interview with Barry Schrader in the coming weeks, so stay tuned for that as well.

"Active in the promotion of electro-acoustic music, Schrader is the founder and the first president of SEAMUS (Society for Electro-Acoustic Music in the United States). He has been involved with the inauguration and operation of several performance series such as SCREAM (Southern California Resource for Electro-Acoustic Music), the Currents concert series at Theatre Vanguard (the first ongoing series of electro-acoustic music concerts in the U.S.), and the CalArts Electro-Acoustic Music Marathon. He has written for several publications including The New Grove Dictionary of Music and Musicians, Grolier’s Encyclopedia, Contemporary Music Review, and Journal SEAMUS, and is the author of the book Introduction to Electro-Acoustic Music."

via Barry Schrader:

"After what will have been 45 years on the faculty of the CalArts School of Music, I've decided to retire at the end of this academic year. Starting as a graduate student at CalArts in 1970, I was hired on the faculty by Mel Powell, then the Dean of the School of Music, in 1971. It’s been an incredible adventure to have experienced the evolution of the school from its beginnings at the temporary Burbank Villa Cabrini campus to its current incarnation as The Herb Alpert School of Music at CalArts. Along the way I’ve been fortunate to have had superb composers and performers as colleagues and friends, a host of talented students, and also to have met and worked with many brilliant people in various areas of the arts throughout the world.

To mark my retirement from CalArts, I’ve decided to present a farewell concert containing a variety of works from a forty-year period. This program will be held on Saturday, September 26, at 8:00 pm in CalArts’ Roy O. Disney Hall. Admission is free, and there will be a reception following the concert. I’ll also be giving away a limited number of my CDs to those that attend the event.

The concert will feature Mark Menzies on violin playing Fallen Sparrow, and Vicki Ray on piano performing Ravel. Also on the concert will be the original quadraphonic version of Trinity, along with short sections of Monkey King and The Barnum Museum. Adam Beckett’s groundbreaking 1973 film Heavy-Light will be shown, along with Michael Scroggins’ early computer video, 1921>1989.

For those that wish to hear and view the concert online, it will be available live on the live ROD Webcast."

ADDAC803 VC Quadraphonic Spatializer

Published on May 19, 2015 ADDAC System

ADDAC803 VC Quadraphonic Spatializer Part 2

"This is our Quadraphonic output module.

Using the VBAP (Vector-Based Amplitude Panning) principle it allows to position a mono signal over a quadraphonic speaker array for sound spatialization. The VBAP algorithm can be controlled by Cartesian or Polar methods.

Sound path is fully analogue featuring 4 high quality VCA's.
Featuring both 1/4 inch and 3.5mm jacks for adapter free connections.

Four 16 bit CV outputs mirror the signal sent to the VCA's control, when connected to 4 external VCA's these can be used for Polar Mixing of 4 diferent sound sources.

The 2 Filter CV outputs react according to the distance from the center point. The + output increases as the sound gets further away from the center of the room allowing to sync a Low Pass Filter to the input sound so that as it moves away from the center the High Frequencies get attenuated further increasing the spatialization experience. Another good practice would be to sync a reverb dry/wet signal as well so that the sounds gets more difused as it moves away from the center into the horizon.
Both the filter and the reverb should be plugged between the sound source and the 803, in order for the incoming sound to be processed before being routed to the 4 outputs.

The X and Y CV outputs mirror the cartesian sound position between 0 and +5v."

Spatial Frontiers: Quadraphonic Concert Featuring Three Buchla Music Easels This Friday

via Todd Barton:

"Spatial Frontiers: Quadraphonic Concert

Noon, Friday, April 24, 2015
Schneider Museum of Art
With special guest Eden Mononym

The next performance is Friday, April 24, noon at the Schneider Museum of Art on the campus of Southern Oregon University. Todd Barton and Bruce Bayard are joined by Eden Mononym and all three perform on the Buchla Music Easel. The performance begins at Noon and is free and open to the public.

The series continues the exploration of space as a compositional tool, this time, expanding the quadraphonic sound into all four galleries of the Museum. For this performance, in addition to the Buchla Easel: Electric Music Box, Todd adds the Japanese Sho to the ensemble, to continue the investigation of acoustic instruments in the mix.

Eden Mononym is a local sound artist, working for Buchla Electronic Musical Instruments. He began tape splicing at the age of 10, essentially planting the seeds for a self taught journey. Exploring various techniques from modular electronics, computers, live coding, acoustics, to the avant-garde. Eden is always searching for an electro-organic sound, with a focus on expression based approaches.

Todd Barton is former Director of Composition Studies for the Music Department at Southern Oregon University and Resident Composer Emeritus for the Oregon Shakespeare Festival. Todd is currently Consulting Artist for Buchla Electronic Musical Instruments. After four decades of exploration, Barton is still delving deeply into the ever-expanding frontiers of musical expression: from his DNA derived Genome Music to innovative scores for plays at the Oregon Shakespeare Festival; from performances of Zen Shakuhachi Meditation Music to avant-garde music for electronic synthesizers and computers; from performing with luminaries of jazz and poetry to lecturing on music and composition from the Middle Ages to the 21st Century.

Bruce Bayard began oil painting at age 9, and although briefly attended the University of New Mexico, is largely self-taught. He has worked in various media and techniques including oil, acrylic, casein, collage, lithography, etching, screen printing, pencil, crayon, encaustic and assemblage.

In 2000, Bayard began an exploration into digital technology as a means of creating art, producing archival pigment prints. During the last couple years, he has been exploring performance and multimedia improvisation with an ensemble that combines sound, voice, dance, poetry and video collage.

all best wishes,
Todd"
