oscilloscope (per-channel)

the "Oscilloscope (per-channel)" window displays several oscilloscope views (one per channel).

oscilloscope per-channel configuration view

right-clicking the view will display the configuration view shown above:

  • Columns: sets the amount of columns for the oscilloscope views.
  • Size (ms): sets how much of a channel's output is captured for the oscilloscope view.
  • Center waveform: when enabled, the displayed waveforms will be centered using an auto-correlation algorithm.
  • Automatic columns: sets the number of columns based on the number of channels.
    • Off: use the Columns setting.
    • Mode 1: always fewer columns than rows.
    • Mode 2: bias slightly toward more columns.
    • Mode 3: always more columns than rows.
  • Amplitude: scales amplitude for all oscilloscope views.
  • Gradient: this allows you to use a gradient for determining the waveforms' colors instead of a single color. see the gradient section for more information.
    • if this option is off, a color selector will be displayed. right-click on it for some options:
      • select between the square selector and the color wheel selector.
      • Alpha bar: display an opacity bar.
  • Text format: this allows you to display some text on each oscilloscope view. the following codes may be used:
    • %c: channel name
    • %C: channel short name
    • %d: channel number (starting from 0)
    • %D: channel number (starting from 1)
    • %n: channel note
    • %i: instrument name
    • %I: instrument number (decimal)
    • %x: instrument number (hex)
    • %s: chip name
    • %p: chip part number
    • %S: chip ID
    • %v: volume (decimal)
    • %V: volume (percentage)
    • %b: volume (hex)
    • %l: new line
    • %%: percent sign

click on OK to return to the main view.

gradient

oscilloscope per-channel gradient configuration view

when enabling the Gradient setting, a gradient view is displayed in where circular "points" can be placed. each point adds a color spot. the resulting image is used to look up the waveform's color as determined by each axis.

  • right-click to place a point.

  • left-click on a point to change its color:

    • a color picker is displayed, alongside two settings.
    • Distance: the size of the circle.
    • Spread: the size of the solid center of the circle. increasing it fills more of the circle with the color.

  • middle-click on a point to delete it.

  • Background: sets the gradient's background color.

  • X Axis: determines what the horizontal axis maps to.

  • Y Axis: determines what the vertical axis maps to. these can be set to the following:

    • None (0%): always left or bottom
    • None (50%): always center
    • None (100%): always right or top
    • Frequency: changes color with frequency
    • Volume: changes color with volume
    • Channel: changes color based on channel number (first channel is 0% and last is 100%)
    • Brightness: currently does nothing
    • Note Trigger: changes color when a new note is played
