CV In
Bitwig Platform
External control voltage input with a configurable four-pole low-pass smoother.
What it does
CV In reads a selected hardware CV path and makes the calibrated voltage available as a Grid signal. Its smoothing cutoff applies a four-pole low-pass filter to suppress noise or rapid voltage changes.
Controls and ports
| Control | Label | Official description |
|---|---|---|
out |
Out | Control voltage (CV) signals from a selected external path |
path |
Control Voltage Path | Incoming CV path to use |
smooth_filt |
Smooth Filt | Cutoff frequency for a 4-pole low-pass filter applied to the incoming signal |
Practical uses
- Bring an Eurorack envelope, LFO, or sequencer voltage into a Grid patch.
- Lower the smoothing cutoff when hardware noise causes unstable modulation.
Things to know
- Reliable DC and slow CV requires a DC-coupled interface input.
- Four-pole smoothing changes timing as well as noise, adding lag and phase shift.
- Voltage-to-Grid scaling belongs to Bitwig's configured CV path and hardware calibration.
Technical details
No Nitro implementation has been confirmed for this visible module. The behavior is described conservatively from module metadata and editorial research.
The visible chain is out = lowpass4(calibrated_hardware_cv, cutoff). The exact filter topology, calibration equation, clipping, and update boundary have not been recovered as a Nitro body.
Open questions
- Measure voltage scaling, polarity/range, filter response and resonance, latency, DC accuracy, clipping, missing hardware, and sample-rate dependence.
Version and sources
Checked against Bitwig Studio 6.0.6. This page combines Bitwig's module metadata, the existing Grid course and guides, and Nitro analysis where the mapping is strong enough to support a technical statement.
