Oscilloscope

A dual-trace time-domain monitor with stereo, voice-display, triggering, and pitch-tracking modes.

What it does #

Oscilloscope draws one or two incoming signals against time while passing them through for continued patching. Slow and Fast modes use a free or external redraw trigger; Pitch mode follows the device's incoming note pitch to stabilize periodic waveforms.

Controls and ports #

Control	Label	Official description
trigger_in	Trigger In	[When in Slow or Fast mode] Trigger clears and redraws the module's trace
stereo	Stereo	When enabled, shows the left and right channels of Signal In 1 (and temporarily disables Signal In 2). The left channel is shown with Signal In 1's color, and the right channel is white.
mode	Mode [slow, fast, or pitch]	Set the tracking speed to Slow or Fast, or set to follow the device's incoming note Pitch signals
display	Display	What voice(s) is being displayed:
y_max	Y Max	Maximum Y value on the scope
y-axis	Y-Axis	Domain for amplitude:
y_bipolar	Y Bipolar	Makes the display bipolar (instead of going from zero to Y Maximum)

Practical uses #

• Inspect oscillator shape, clipping, envelope timing, phase relationships, or control-signal boundaries without interrupting the cable path.
• Compare two related signals, or enable Stereo to compare the left and right lanes of one source.

Things to know #

• It is a monitor, not an audio processor; the through output should remain numerically unchanged.
• All-voices display is a sum and can look larger or more complex than any individual voice.
• Pitch mode stabilizes periodic signals from note pitch but is not a general trigger guarantee for noisy or inharmonic audio.
• Display sampling and drawing may omit information that remains present in the audio stream.

Technical details #

A medium-confidence Nitro implementation candidate supports the technical summary, but the visible-module mapping remains inferred.

The visible scope buffers decimated samples for UI rendering while its through ports conceptually copy the input. A related signal/oscilloscope_level_trigger helper stores the previous sample and emits an event on a threshold crossing; however, the recovered down-slope branch duplicates the up-slope condition, so it cannot establish the complete trigger implementation. Buffer length, decimation, Pitch-mode timebase, and voice aggregation are not recovered.

Open questions #

• Measure through-port null, buffer length, redraw rate, trigger edge/threshold, Pitch-mode cycles, decimation, aliasing, Last/All voice selection, stereo behavior, Y-axis modes, and reset.

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.
