TLN 712 Doomsday Machine

Demo # 1 video upload by Lower West Side Studio

"Demonstration of the Tellun Corporation TLN-712 Doomsday Machine module. This version of the TLN-712 is in MU format and is built by Lower West Side Studio.

The TLN-712 is a wave shaping module containing 4 voltage controlled LFOs and 2 separate wave shapers. It can enhance, modify and destroy sound.

In this video 2 triangle waves are fed into the Cascading Biogenic Pulse section of the module. It's quite awesome.

The TLN-712 Doomsday Machine designed by The Tellun Corporation combines 4 voltage controlled Low Frequency Oscillators with 2 Waveform Animators. Combined together this incredible module can produce or mangle waveforms allowing you to create some incredible audible experiences.

The TLN-712 Doomsday Machine is a voltage controlled waveform animator for modular synthesizers.

Originally conceived as two separate modules, the TLN-712 comprises two different animation circuits and four voltage-controlled LFOs (low frequency oscillators).

The first animator (Thalaran Radiation Emitter) is based on the Multi-Phase Waveform Animator by Bernie Hutchins.

The second animator (Cascading Biogenic Pulse) is based on the Pulse Width Multiplier by Craig Anderton. Both circuits require several modulation sources in order to generate their animation effect.

The four built-in LFOs provide the necessary modulation without the need for external modules. Patch points are included for external modulation, if desired.

Features:

Four modulation sources. Each source has an OFFSET pot to set the initial modulation point, a MOD input jack with attenuator to allow for external control of modulation, and an internal LFO. All four modulation sources are internally connected to both animators.

Each internal LFO has a RATE pot, an LED to provide visual indication of the rate, and a DEPTH pot to set the amount of LFO fed to the animators. Each LFO has a 10 Vpp triangle wave output that is available for external use. Internally, each LFO provides a sine wave to the two animators.

The rate and depth of all LFOs can be changed en masse using the EXT RATE and EXT DEPTH jacks and attenuators. Use these with your keyboard control voltage, modulation wheel, or foot pedal to control the speed and depth of animation.

The Thalaran Radiation Emitter has one input jack (IN A) and three output jacks (SAW, TRI, STEP). A sawtooth wave is normally applied to IN A, but sine or triangle waves can also be used (almost any waveform except pulse waves will produce some kind of useful output). With a sawtooth input, the SAW output comprises the input signal plus four phase shifted versions of the input signal (sounds like five sawtooth waves). The phase shift is controlled by the four modulation sources. The TRI output provides a similar effect but with five triangle waves. The STEP output is a bizarre staircase waveform where the depth of each step is controlled by the four modulation sources.

The Cascading Biogenic Pulse has two input jacks (IN B and AUX) and four output jacks (PULSE 1-4). A triangle wave is normally applied to IN B, but sine or sawtooth waves can also be used (almost any waveform except pulse waves will work). The four PULSE outputs produce an intense pulse width modulation (PWM) effect with single, double, triple, and quadruple pulses appearing at outputs 1-4 respectively. Think of it as PWM on steroids. The PWM effect is controlled by the four modulation sources. The AUX input can be used to provide an additional level of animation, or to cascade two TLN-712s to get even more intense PWM, or to provide a cross-product effect.

All inputs and outputs are DC-coupled. Either animator can be used to produce strangely wonderful waveforms for modulating other signals. The Cascading Biogenic Pulse can even be used to generate rhythmic gates and triggers.

All inputs and outputs handle 10 Vpp audio signals and 5 volt control voltage signals (modular standard).
