Harvestman – Bionic Lester Overview

Harvestman – Bionic Lester Overview

The Bionic lester is a two channel -12db/oct switched capacitor multimode filter.

Each channel has 3 outputs: Dedicated lowpass, dedicated bandpass, and a multimode output selectable between highpass, allpass or notch. Filter mode selection is shared between filters. When no LEDs are selected, it is in secondary notch mode. Secondary notch mode has less distortion and a higher maximum resonance compared to the lit LED notch.

Channel 1 is a standard filter setup with a Harvestman twist
Input 1 – Normalled to output 1 and output 2
Gain – Distortion starts to occur around 12 o clock knob position.
Alias – At low cutoff frequencies, you’ll be able to hear the aliasing/clock noise)
– When set to HI, self oscillation is possible with high resonance with no input.
– The filter cutoff is accomplished by clocking the switched capacitor filter with a high-speed VCO. The Cutoff knobs are basically controlling the frequency of this VCO. – The actual cutoff frequency is a divided down ratio of this high speed osc frequency – the “aliasing” control makes the ratio lower so the sampling rate of the system is worse.
Cutoff – Channel A cutoff controls are normalled to the B cv input attenuator if nothing is plugged into B.
Resonance – Shared between both filters

Channel 2 breathes chaos and has access to all functions of Channel 1 including its Resonance but the heart and distinct aural differences between this filter and every other filter is the Clock Source section.

Clock Source – Selects between clock source A (filter 1) or clock source B (filter 2).
-If there is a large difference in cutoff frequencies, the filters generate more beat frequencies than the input signal themselves.

Split-Peak example
Setup: Signal into Channel 1 input, outputs from Low Pass from both channels, cutoff B CV knob all the way up, both gains all the way up, resonance all the way up, cutoff b at a low value.
Sweep cutoff frequency A and you should hear a phasing type effect. The higher the value of cutoff B, the longer the distance between peaks.

A mixer expander is coming later that is a 2×3 mixer taking all of the I/O from the module and creating a mix of it, with VCAs on the two outputs. Mute switches are available too. It also works on external signals.

Devine Expansion Pack for Animoog

Introducing the Devine Expansion Pack for Animoog. 32 original presets & 43 new timbres handcrafted.

I have been a fan of Animoog since the day it was launched. Animoog’s ability to mix and match classic analogue waveforms and also digital waveforms is amazing! Being able to sweep, automate, and control them within the Anisotropic Synth Engine is what makes it such an expressive tool for creating new sounds. With the Devine Expansion Pack, I wanted to develop a sound set that took full advantage of all Animoog’s features. Something that was unique and could be played musically or controlled chaotically. The ultimate goal was to create a set of futuristic synth sounds that inspire new ideas and new music. I hope you all enjoy it,

Harvestman – Bionic Lester

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.
