Klavis CalTrans
OverviewKlavis CalTrans
Quad programmable Volt/Octave calibrator and transposer
Four V/Oct processing channels, each with
Curve correction and range expansion for any VCO, VCF or other oscillating circuit with a CV acting on pitch
Works with other range systems (e.g. Buchla)
1:1 in/out V/Oct mode for use without calibration
Switchable semitone quantizer
Adjustable portamento time
Adjustable glissando time
Separate semitone and octave transpose click-encoders
Inputs cascading with no added load for stable pitch control
Four user presets storing transpose, portamento and glissando
Storage of the calibration profile for each channel
Maximum voltage range covering 10 octaves
Presets, calibration and current state retained over power cycle
Volt/Oct inputs factory-calibrated in flash memory
User adjustable input scaling to correct voltage inaccuracies in your sources
Easy firmware update via a simple audio file
High-quality push-encoders with metal shaft
Skiff-friendly & compact module
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.
VCOs that don't require calibration can be used simply in "Neutral" mode to benefit from the transposition and other musical features.
A pair of rotary encoders with detent allow a precise selection of octaves and semitones.
VCOs whose tracking doesn’t go high (low) enough to follow the leader will see their pitch repositioned in their highest (lowest) 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.
The latest firmware adds user editable scaling of the inputs to match sources that do not generate perfect 1V per octave signals.
