Notes: Programmable Volt/Octave CV calibrator and transposer

Clever four-channel utility module designed to make it easier to achieve perfect oscillator tracking and transpose CV signals. Also includes some neat quantising and portamento features.

The CalTrans solves issues encountered when playing tonal music with a modular system: tracking problems, curves unrelated to Volt per octave ratio, limited octave range, cumbersome transpose, ...

The CalTrans corrects and expands the range of troublesome VCOs and brings V/Oct tracking to anything that oscillates.

Besides calibration, the CalTrans offers live play features. Each channel can be quantized and any combination of them transposed jointly.

A pair of rotary encoders with detent allow an precise selection of octaves and semitones.

VCOs whose tracking doesn't go high enough to follow the leader will see their pitch repositioned in their highest possible octave so that the global harmony is unaffected.

You can add a pinch of portamento and glissando to each channel and save the whole in user presets.

Firmware 1.17 offers:
* User editable input scaling to match sources that don't generate perfect 1V per octave signals.
* Complete rewrite of the main processing with higher precision.
* ... and the unavoidable fixes and tweaks ;-)

The updated user manual 1.4 is much expanded with operations described in exquisite details :-)
.. and a version 1.5 corrects a mistake in the input calibration description and eases the reading elsewhere.

Notes: The ComPair is a versatile yet compact and affordable tool to expand your sonic arsenal. Voltage comparison is used to trigger events, reshape and mangle waveforms and realize level-dependent logic functions.

Two sections can be used independently as voltage against manual setting comparison. Additionally, the first section allows voltage against voltage comparison with offset adjustment.

When used globally, the module offers a powerful window comparator with CV-controlled top setting.

The outputs benefit from three triple-position switches, allowing independently settable polarity and muting.

Three LEDs indicate the output logic to keep track of what's happening.

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.
