The scope & analyzer

The Scope band gives you a live picture of the sound: what the waveform looks like, how the stereo field sits, where the energy is across the frequency range, and how that spectrum moves over time. It is a monitoring tool, so it never changes the audio; it just shows you what is already there. Like the note editor, the scope can pop out into its own resizable window when you want a bigger view.

The four display modes

A Mode selector switches what the display draws. All four modes share the same source taps and readouts.

Mode	What it shows	Use it for
Wave	A phosphor oscilloscope: the signal drawn over time, with trailing persistence.	Reading the shape of a waveform, checking a filter’s motion, watching an envelope open and close.
XY	A vectorscope: the two source taps plotted against each other.	Judging stereo width and phase; a thin diagonal line is mono, a wide splash is stereo.
Spectrum	An FFT frequency analyzer on a log-frequency axis, with a peak-hold trace riding the maxima.	Seeing where the energy sits: the fundamental, harmonics, resonance peaks, and where a filter is cutting.
Spectrogram	A scrolling frequency-vs-time waterfall: frequency runs up the display, time scrolls left to right (newest on the right), with brightness for level.	Watching how a sound’s spectrum evolves: sweeps, movement, and how partials come and go over time.

The log-frequency axis and the peak-hold trace in Spectrum are always on; there is no separate toggle for either. Spectrogram uses the same log-frequency mapping as Spectrum, so the two read the same way vertically.

Both FFT modes are labelled so you can place what you see. Spectrum marks the frequency grid along the bottom (30, 50, 100, 200, 500 Hz, then 1k, 2k, 5k, 10k, 20k, with the decades brightest) and a dB scale (0, -20, -40, -60) up the left edge. Spectrogram carries the same frequency labels up its left edge, since frequency runs vertically there, so you can read the exact band a partial or a sweep sits in.

Sources: what the scope is watching

The scope can tap the signal at different points in the voice path, and it can show two taps at once for comparison.

• Source picks the primary tap: Master (the final output), Pre-FX (the voice sum before the effects rack), Filter (after the filter stage), or Osc (the raw oscillator mix, before the filter). Moving the tap earlier in the chain lets you isolate what one stage is doing.
• Source 2 overlays a second trace from another tap, so you can compare two points directly (the oscillator against the filtered signal, say, to see exactly what the filter removed). Set it to Off for a single clean trace. In XY mode the two sources are what get plotted against each other.

Trigger and timebase (Wave mode)

In Wave mode a trigger stabilises a repeating waveform so it stands still instead of scrolling:

• Trigger Slope sets whether the trace starts on a Rising or Falling crossing of the trigger level.
• Trigger Level is the amplitude the trace waits to cross before it draws. Drag it to set the level; double-click to re-centre it at zero.
• Timebase zooms the time axis, shown as the sample window it is drawing. Zoom in to inspect a single cycle, or out to see a longer stretch.
• Freeze holds the current display so you can study it. It reads Live when running and Frozen when held; it works in every mode, not just Wave.

The readouts strip

Along the top of the display, a compact strip reports the numbers behind the picture:

• PEAK and RMS show the current peak and average level in dB, a quick check for how hot the signal is running.
• PITCH shows an estimated pitch: the strongest frequency and the nearest note name (for example 440.0 Hz A4). It is a handy tuning and interval reference while you play. PITCH is hidden in XY mode, where a single pitch has no meaning.
