# oscilloscope (per-channel)
|
|
|
|
the "Oscilloscope (per-channel)" dialog shows an individual oscilloscope for each channel during playback.
|
|
|
|
|
|
|
|
right-clicking within the view will change it to the configuration view shown above:
|
|
- **Columns**: arranges oscilloscopes into this many columns.
|
|
- **Size (ms)**: sets what length of audio is visible in each oscilloscope.
|
|
- **Center waveform**: does its best to latch the waveform to the channel's note frequency and centers the display.
|
|
- **Amplitude**: scales amplitude for all oscilloscopes.
|
|
- **Gradient**: see below.
|
|
- the color selector sets the color for all waveforms. right-clicking on it pops up an option dialog:
|
|
- select between the square selector and the color wheel selector.
|
|
- **Alpha bar**: adds a transparency selector.
|
|
- the boxes below that are for selecting colors numerically by red-green-blue-alpha, hue-saturation-value-alpha, and HTML-style RGBA in hex.
|
|
- **Text format**: this string determins what text is shown in the top-left of each oscilloscope. it can be any text, and the following shortcodes will be replaced with information about the channel:
|
|
- `%c`: channel name
|
|
- `%C`: channel short name
|
|
- `%d`: channel number (starting from 0)
|
|
- `%D`: channel number (starting from 1)
|
|
- `%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)
|
|
- `%%`: percent sign
|
|
- The OK button returns from options view to the oscilloscopes.
|

in this mode, the color selector is replaced by a square field onto which circular "stops" can be placed. each stop adds a soft circle of color. the resulting image is used to look up the oscilloscope color as determined by each axis.
|
|
|
|
- right-click to place a stop.
|
|
- left-click on a stop to change its color. the color selector is the same as above, with two additions:
|
|
- **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 target color.
|
|
|
|
- **Background**: sets background color for entire field.
|
|
- **X Axis**: determines what the horizontal maps to, from left to right.\
|
|
**Y Axis**: determines what the vertical maps to, from bottom to top. these can be set to the following:
|
|
- **None (0%)**: stays at the left or bottom.
|
|
- **None (50%)**: stays at the center.
|
|
- **None (100%)**: stays at the right or top.
|
|
- **Frequency**: changes color with note frequency.
|
|
- **Volume**: changes color with volume.
|
|
- **Channel**: changes color based on channel number.
|
|
- **Brightness**: {{document this}}
|
|
- **Note Trigger**: changes color when a new note is played.
