Livewire AFG (Audio Frequency Generator)

The Audio Frequency Generator is a true vintage-style analogue VCO capable of producing unique, harmonically complex waveforms. 

Outside, the AFG presents the user with extensive panel controls for maximum flexibility and usability inside, the pure analogue circuitry adheres to a strict design philosophy rooted in mid-1970s technology and construction techniques.

Features

• 8 simultaneous waveform outputs
• A total of 27 distinct waveforms are possible
• Sub-octave with switchable square or sawtooth waveforms
• Unique Animated Pulse & Alien Saw waveforms
• Programmable ﾑNaturalﾒ or ﾑLaboratoryﾒ sine wave modes
• Alternate waveform set is activated on all outputs simultaneously with Matter/Anti-Matter switch
• Select between 2 different Anti-Matter waveform sets via pcb jumper
• 9 CV inputs, each with dedicated attenuators, with the exception of the two 1v/oct inputs
• 2 FM inputs, both switchable between linear & exponential
• Dedicated sync in/out

Harmonic Animation

The Harmonic Animation section of the AFG controls the harmonic content of the Animated Pulses & Alien Saws waveforms.

The Animated Pulses waveform is synthesized by four control parameters, each having a manual adjustment knob and CV input with dedicated attenuator:

• Positive Pulse Width Modulation (+PWM) ﾖ controls the width of the two pulses on the top (or positive) side of the waveform
• Negative Pulse Width Modulation (-PWM) ﾖ controls the width of the two pulses on the bottom (or negative) side of the waveform
• Positive Phase Position Modulation (+PPM) ﾖ controls the relative phase position of the two positive pulses (in relation to each other)
• Negative Phase Position Modulation (-PPM) � � controls the relative phase position of the two negative pulses (in relation to each other)

The Alien Saws output is a bizarre, multi-toothed saw waveform that is derived from the Animated Pulses waveform. Itﾒs harmonic content is also synthesized by the four control parameters of the Harmonic Animation section, but in different and more enigmatic ways.


Expandability

The Livewire Audio Frequency Generator is designed with expandability in mind. There are currently 3 new modules in the works, which are intended to further expand upon the AFGﾒs sound shaping capabilities:

X-Mod Controller
Provides 4 channels of fully routable cross-modulation between 2 AFGsﾅ 2 channels in each direction. Each channel features manually or voltage controlled modulation depth.

Audio Compositor
Enables the user to coalesce harmonics from all 8 of the AFGﾒs output waveforms into a single mono or 2 stereo outputs. Eight channels of bi-polar, voltage controlled mixing determine amplitude & panning of each waveform in the stereo outputs or amplitude & phase inversion in the mono output.
