Tiptop Audio + Buchla Sequential Voltage Source, Dual Voltage Processor Coming This Summer In Eurorack Format

At Superbooth 2022, Tiptop Audio is previewing the next modules in its official line of Buchla 200 Series Eurorack modules.

The first batch of the 245t Sequential Voltage Source and 257t Dual Voltage Processor, above, are in production and are expected to ship this Summer. Both are Eurorack translations of classic Buchla 200 Series modules from ’70s.

Tiptop Audio also shared an update on their version of the 292 Quad Lo Pass Gate, which will feature handmade vactrols that they say will “satisfy the ears of the most die-hard Buchla bongo fans”, adding “Users will be able to build out their 200t systems with the classic Buchla signal chain.”

In addition to the Tiptop Audio & Buchla news, Tiptop announced that they are introducing an all-black Mantis Eurorack case.

The new black Mantis is identical in specs and price to the original. This case is made with black ABS with an overcoating to ensure a homogenous shade in various light conditions.

The first batch of black Mantis is limited and will be available very soon with additional quantities that should be ready toward the end of Summer. The gray Mantis will also be available again, and they plan to have them shipping in large quantities in the coming months.

Finally, Tiptop Audio has added black faceplates for the following modules: Miso, Forbidden Planet, Z8000, Z2040, Mix7. The black Z8000 is now released and the others will be sent to retailers in the coming weeks.

Pittsburgh Modular Flamingo Module Overview & Demo

[embedded content]

Pittsburgh Modular shared this extended intro video for their new Flamingo Eurorack module.

The module is part of PM’s ‘Safari’ series, a line of limited edition modules that are intended as proof of concepts for exploring new design ideas.

In the video, PM’s Richard Nicol and Michael Johnsen discuss the design of the Flamingo and demonstrate its sonic possibilities.

They say that the Flamingo builds on a concept discussed, but never implemented, by Don Buchla.  The Flamingo introduces Center Clipping and Harmonic Interpolation to analog synthesis.

  • Center Clipping is a method of shaping a waveform from the inside out. Independently pulling the top half or bottom half of a waveform toward the middle.
  • Taking it a step further, Overtone adds another dimension to the analog waveform gymnastics by sliding and inverting the top and/or bottom of the waveform back on itself creating new types of wave shapes and shifting the fundamental in and out of focus.
  • The complex wave shaping capabilities of Center Clipping come at a cost. Center Clipping is a destructive process that can dramatically reduce the amplitude of waveforms. Harmonic Interpolation is the process of attempting to restore the center clipped waveform by allowing the analog circuitry to guess what the waveform should look like.

See the PM site for details.

New Album, Buchla Now, Features Modular Music From Suzanne Ciani, Kaitlyn Aurelia Smith, Steve Horelick & Others

To celebrate its 5th year and 20th release, cassette label Ultraviolet Light has cooked up something truly special: Buchla Now, a collection of new music created on synthesizers designed by Don Buchla.

Buchla Now features music from Marcia Bassett, Suzanne Ciani, Dan Deacon, Jonathan Fitoussi, Steve Horelick, Kaitlyn Aurelia Smith, Hans Tammen, and compilation curator Todd Barton.

Ciani once said of Don Buchla that his “unique mindset allowed him to be outside the popular notion of what electronic music was.” Each of the featured artists, in their own way, carries on this tradition of boundary-pushing music, expanding the notion of what music can be.

You can preview the album below or at Bandcamp:


A1. Jonathan Fitoussi, Planète Sauvage (Buchla Music Easel)
A2. Todd Barton, Apeiron (Buchla Music Easel)
A3. Kaitlyn Aurelia Smith, Moon like a Marble (Buchla Music Easel)
A4. Marcia Bassett, Influence Scrambler (Buchla 200 Modular)
B1. Dan Deacon, Unseen Objects (Buchla Easel Command)
B2. Hans Tammen, ääniä (Buchla Music Easel)
B3. Steve Horelick, Spirals of an Inner Life (Buchla Music Easel and Buchla 200e)
B4. Suzanne Ciani, Empty Skies (Buchla 200e)

Historic Mills College & Center for Contemporary Music Closing

Mills College – a private liberal arts and sciences college in Oakland, California – has announced that it will be closing, after conferring its final degrees in 2023.

The College had been at its current location since 1871.

Mills President Elizabeth L. Hillman says that the decision is a result of a combination of the economic burdens of the COVID-19 pandemic, structural changes across higher education, and Mills’ declining enrollment and budget deficits.

The Center For Contemporary Music

The College is notable to the world of electronic music as the home of the Center for Contemporary Music (CCM).

CCM got its start in 1961 as the San Francisco Tape Music Center, co-founded by former Mills music students Morton Subotnick and Ramon Sender, with help from Pauline Oliveros. In 1966 the center moved to Mills College, where it was later renamed the Center for Contemporary Music.

Artists associated with the Tape Music Center or CCM include Robert Ashley, David Behrman, David Rosenboom, Laurie Anderson, Guðmundur Steinn Gunnarsson, Holly Herndon, Terry Riley, Steve Reich and many others.

The Original Buchla 100

CCM is also the home of the original Buchla 100 system.

In this 2017 Waveshaper Media video, founders Subotnick and Sender meet with Professor Maggi Payne and talk about working with Don Buchla in 1963 to create the early modular system:

Free Synth From Eventide, ‘Pendulate’, Unleashes Chaos

[embedded content]

Eventide has released a new software synthesizer, Newfangled Audio’s Pendulate, that they describe as ‘a chaotic monosynth’.

Pendulate is based on the physics of a double pendulum. What initially looks like randomness, contains underlying patterns, interconnectedness, constant feedback loops, repetition, self-similarity, fractals, and self-organization.

When designing the Pendulate oscillator, great care was taken to bring out these underlying patterns. The result is an oscillator that can smoothly fade from a sine wave to total chaos, with an expanse of territory to explore in between.


  • Novel chaotic oscillator, based on the double pendulum
  • Wavefolder based on the one in the Buchla 259 Complex Waveform Generator, adding MIX and CUTOFF
  • Low Pass Gate based on the Buchla 292 adds controls for POLES and RESONANCE
  • Modulation UI allows modulation over every control from the main page, allowing up to 169 simultaneous modulation routings
  • MPE support allows expressive control from innovative new controllers
  • Envelope and LFO each have multiple outputs generated at once
  • Every mod output to every control means up to 221 modulation points in an intuitive single pane
  • The Double Pendulum, Wavefolder, and Low Pass Gate modules each have animations to show how each module responds to your input, and to modulation
  • Three unique color schemes to customize your look
  • 136 Presets including artist presets from Matt Lange and Matthew Wang
