Manufacturer's description
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.
Features
- 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
- Curve correction and range expansion for any VCO, VCF or other oscillating circuit with a CV acting on pitch
- 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
- Settings restored after power cycle
- Easy firmware update via a simple audio file
- High-quality push-encoders with metal shaft
- Skiff-friendly & compact module
- User manual in English and German
- Width: 6HP
- Depth: 36mm
- Power: 44 mA +12V / 8 mA -12V / 0 mA 5V

Shipping methods
All EU orders are shipped via UPS. We offer two service levels:
- UPS Standard – our default shipping option. Delivery times vary by country (see estimated delivery times below).
- UPS Express Saver – next business day delivery to most EU destinations.
Each product page shows the estimated delivery time for your location, so you'll always know what to expect before you order.

| Sweden | 3–5 |
These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.
Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
