Harvestman – Bionic Lester

Picture from Juliana Jaeger

dual 12db/oct switched capacitor multimode filter with mode selction and clock disruption.

Bionic Lester is a dual multimode filter capable of many operational modes. Each side has dedicated lowpass and bandpass outputs, and the third output for each side can be switched between highpass, allpass, or notch. The input amplifiers for each filter are scaled to allow some distortion. The character of this distortion changes with the mode setting.

Bionic Lester has some normalled signal paths for convenient patching. The sum of the first channel’s manual cutoff control and CV input are normalled to the CV input for the second channel. This allows you to control both filter sections with a single hand (or CV), useful for dual-peak or allpass phasing applications. The audio input for the first channel is also normalled to the second to facilitate parallel filtering. The filter cutoffs are determined by dividing down a high-frequency clock generator.

For the second channel, you can choose either the first or second channel’s generator as a clock source. If you select both clock generators, absolutely horrifying audio garbage will result. A pushbutton control for selecting the desired amount of aliasing (minimum or maximum) applies to both sections. Resonance is voltage-controllable.

Because Lester is a switched-capacitor filter, the user must be warned of some of its characteristics. The aliasing, third output mode selection, and resonance settings are shared between both units. At lower cutoff frequencies, some aliasing may be present in the output signal depending on your resonance, aliasing, and mode settings, as well as the type of input signal. Bionic Lester does not self-oscillate using the onboard resonance control.

An expander unit will be released soon. It is a 2×3 bipolar mixer (with mutes) that invisibly attaches to Bionic Lester for patchcord-free mixing of the six outputs, with dual VCA feedback paths back into the filter sections. It also functions standalone as a performance mixer, with front-panel knobs and jacks that are also useful for injecting external signals and effects into the Lester core.

Keith Fullerton Whitman – Chicago, IL

One of our Workspace and Environment interviewees came into down a couple weeks ago. Here is his performance. Here is his interview.

At long last, Keith Fullerton Whitman makes his Lampo debut. To mark the special occasion, he offers the U.S. premiere of “Rhythmes Naturels,” created at the legendary INA-GRM studios, plus a live modular synth improvisation.

Alors, last October Whitman spent a week in Paris, commissioned to develop a new piece for François Bayle’s Acousmonium, an 80-speaker sound system designed in 1974 for the Groupe de Recherches Musicales. Pierre Schaeffer formed GRM, a studio and collective, in the late 1950s to encourage the development of electronic music. Members included Luc Ferrari, Iannis Xenakis, Bernard Parmegiani, among other lions; in the late 1960s Bayle became its director. For a whelp like Keith, the residency was “a life-long dream come true.” And, he says, “The piece turned out exactly as I hoped.”

Here, he’ll do his new work in a 4-channel mix. Here, he talks about the residency, etc.

Keith Fullerton Whitman (b. 1973, Bergen County, N.J.) is a composer and performer obsessed with electronic music, from its mid-century origins in Europe to its contemporary worldwide incarnation as digital music. Currently he is working towards implementing a complete system for live performance of improvised electronic music, which incorporates elements from nearly every era. He has recorded albums influenced by many genres, including ambient music, drone, drill and bass, musique concrète and krautrock. He has recorded and performed using several aliases, of which the most familiar is Hrvatski. Today most of his work is recorded under his real name. Whitman lives in Cambridge, Massachusetts.

WMD – Micro Hadron Collider Filter Overview


The Micro Hadron Collider Filter is a simple module with a common routing scheme found in other filters like the Sherman Filterbank or Schippman Ebb & Flute that, for the uninitiated, can get confusing. To put it in one sentence: The Micro Hadron Collider is a dual channel and dual filter module that utilizes serial and parallel modes.

WMD – Synchrodyne Overview

When receiving the Synchrodyne, I decided to explore it without a manual. This manual-less approach yielded hours of incredible sounds and lots of, “what the hell am I doing?”. I thought it was a self contained experimental noise maker (which it can be), a strong PLL audio modifier (which it can be), or a distortion unit (which it can be). After some research and taking notes, the lightbulb went off and it made sense. I found that the Synchrodyne is “supposed” to be used as an audio modifier. Throw a VCO or any noise source into the filter input and it’ll properly mangle your sound with its 5 sections: VCO, PLL, VCA, Wavefolder, Filter. In short, the VCO’s Pulse Output clocks the PLL and the PLL controls the Filter. This strange signal path creates incredible sounds and can be broken/intercepted anywhere in between.

The WMD Synchrodyne has so much going on, is so deep functionality wise and complex with intricate internal routing paths but I made an overview video that is essentially a ‘getting started’ tutorial.

The WMD official video and manuals contain a lot more information such as:

– The VCO is temperature compensated
– The Filter outputs can self oscilate while the 4p (-24dB) output is more stable.
– Input level of the Wavefolder has a trim-pot on the back that will be easily accessible on the planned expansion.
