How do you listen to it?
The Nebulophone has a 1/4″ mono output designed to be plugged it into any mixer, amp, USB interface, etc. Headphones will work but are not recommended.

Are the keys touch sensitive?
The alligator clip must be used to trigger the keys. You can also wire the key pads to switches as some makers have done.

Pico Paso

The Pico Paso is an analog, light controlled, stepped tone noise synthesizer designed by Dr. Bleep.

It’s based on the concept of the Atari Punk synth, aka Forrest Mims’ stepped tone generator, but uses two triangle wave oscillators that can be combined or used separately. A wave shaper and square wave LFO are used to increase the aural ridiculousness.

How do you listen to it?
The Pico Paso has a 1/4″ mono output designed to be plugged it into any mixer, amp, USB interface, etc. Headphones will not work.

What are the SQU1 and 2 pads between the buttons for?
These are the square wave outputs of the main oscillators, allowing makers to use these signals along with the triangle waves. See the schematics for more info."

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."

Sequential Circuits Prophet 5 Synthesizer with Plastic Overlay

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

via this auction

"Sequential Circuits Prophet 5 original vintage analog polyphonic synthesizer. This is a Revision 2 board that has been upgraded to Revision 3 specifications, including MIDI added and memory banks upgraded to the full 128 offered in later revisions.

Cosmetically it is in Excellent Condition. There is a protective plastic cover on the face which has kept the graphics perfect and helps keep dust from getting inside the board. Corners are all great as shown in photos.

Functionally it is great with the only issue being that a few of the keys 'stutter' sometimes when pressed. I'm told this is an indicator that the key bed or contact wires need cleaning. I've had this in my studio since I bought from the original owner about 3 years ago, but have not used it much for the past year so I can see that. No other known issues. But I am not an expert on these machines and I don't want to dig into it myself so I am selling it 'as is'. Like all these machines the tuning drifts when on for awhile and that is why the automatic TUNE button is right on front in this revision."

Synthrotek MST VCO Now Available!

You've seen the videos first here and here. The Synthrotek MST VCO based on George Mattson's Mattson Mini Modular VCO design is now available here. This completes the Synthrotek MST eurorack line of modules and offers a complete system. Previously a George Mattson system was only available in the proprietary Mattson Mini Modular format along with a few individual eurorack modules from Division-6.

The new MST VCO is available in complete, kit, and PCB/Panel form.

Here's what Synthrotek has to say about the release:

"The circle is complete!

We are super stoked to announce that we now have the first very complete Eurorack monophonic voice in both kit and complete form. The VCO was the last of the modules that are essential to this complete voice. Customers can now build or purchase complete this module to either make a very complete monophonic ‘east-coast’ style voice or add this 100% analog beautiful sounding oscillator to their current system. Like most of the other modules in the MST line, the VCO was designed by synth legend George Mattson."
