Notes: Two fuzz channels based on the fuzz face circuit with a built-in pickup simulator.

Gnarly is a 7 knob beast that will destroy whatever you throw at it. It has many dead zones in the pots that will adjust based on the position of other pots. It's all about finding the sweet spots and living on those fine edges. The transistor pairs on this section are replaceable.

Oomph is a 5 knob bass friendly take on the fuzz face and compliments the upper harmonics of the Gnarly section.

Pickup simulator - Fuzz circuits offer unique sound when paired with the inductance of the pickup coils in a guitar. This why it is often suggested to have fuzz pedals as your first in a pedal chain. So After Later built-in a coil to simulate your eurorack signal being emitted by a guitar pickup. After Later also included a pickup simulator output so you can use it to interface with other fuzz instruments (pedals, modules, etc.).

As an added oddness - you can also input your guitar into the pickup sim output (just don't plug anything into the normal input). This will still get you Eurorack level output. Please don't input Eurorack levels into the pickup sim output.

Tips - Experiment with the pickup simulator and buffered signal. Use the PS.Level to keep the signal low, borderline on cutting out. You find lots of joy in the gnarly section by keeping this level at the edge.

Notes: The Flexshaper is a highly versatile module when it comes to modify evolving voltages in other directions and levels.

Five settings allow you to fold/expand/clip/compress/invert partially or completely any CV or audio signal.

The module can act as an envelope-shaping tool, frequency multiplier, waveshaper, clipper, distortion, limiter, curve changer, and more.

Five CV inputs offer limitless control over the placement of the voltage points for dynamic signal sculpting.

Birth of the product

The idea of the Flexshaper comes from a feature in the Oberheimr Matrix synthesizers called Tracking Generator.

This signal processor was part of the modulation matrix and meant to be virtually inserted between modulation sources and destinations in order to change the shape of the controlling signal.

The Flexshaper applies the same concept using the same 5 shaping points. However, it goes beyond Oberheim's implementation on two main aspects:

It goes fast enough to process signals at full audio rate
The 5 points are dynamically adjustable (CV) in real-time
Besides, the Flexshaper can process adequately bipolar and unipolar Eurorack signals, even changing them one another.

Notes: Reduxer is a stereo sample reducer effect module.

Depends on it's signal, It can produce dynamic range of sounds from knurly bitcrushing to formant/vowel style effects.

Extra resolution

Custom made Redux potentiometer with 300 degrees rotation for extra crashing resolution.

Double the power

Two proprietary sample reduction circuits with extra offset control on channel 2 via the "Spread", lets you create motion in the streo field for wider effect.

Stereo operation

Inputs are normelized - supporting mono to stereo configuration.

Reduction under control

Redux CV input with attenuator for external control of the bit reduction rate.

Reverse polarity protection

The module have proper reverse current and over current protection in its power input stage to protect the module in case it was connected the wrong way or connected to a faulty power supply.

Notes: T-spectrum takes the concept of merging modulation sources and destinations into a single module.

T-spectrum is a spectral processor, an organic sound sculpting tool transforming drastically what passes through it.

The powerful modulation engine lets you hear frequency bands dance, smoothly or frantically. Bring life to your patches with free running or resettable custom drawn modulations.

Maximum automation recording length of 20s for each parameter.

MODE allows to change between 1/2/4/16 (max) bands

FREQ moves the filter initial frequency

SPREAD changes the bandpass filters Q peak

TILT moves the selected peaks around the spectrum.

The integrated touch lightstrip controllers can drive four parameters with looping or one-shot recording playback mode on each track with global RESET input.

Secondary distorted output.

Notes: Alpha Duo is a stereo precision VCA with ring modulation, overdrive and distortion.

Alpha Duo's VCAs have three modes:

1) Two quadrant, for classic VCA behaviour
2) Four quadrant, where the VCA responds to both positive and negative Gain CVs. This creates a classic ring modulator.
3) In four quadrant separate (4S) mode, each of the two VCA channels is controlled by separate gain CVs, turning Alpha Duo into two independent VCA/ring modulators.

Alpha Duo also features three drive modes.

1) In Drive Mode zero the overdrive circuit is not active, giving a clean signal.
2) Drive Mode One is a tube style soft overdrive. Like a tube, the positive and negative parts of the waveform are distorted differently, producing a pleasing, warm fuzz.
3) Drive Mode Two is a harder clip - more like a transistor amplifier - for a harder edged distortion.

Alpha Duo's signal path is DC coupled, so it's great for processing CVs as well as audio.
