Trace Height controls the thickness of the lines in Composite Display mode. A larger number causes thicker lines. You may wish to select a larger Amplitude scale if Automatic Gain Control is turned off, or if you want to see your articulations more clearly.
Automatic Gain Control allows automatic adjustment of the thickness of the lines in Composite Display mode. When Intonia processes soft sounds, the Trace Height is multiplied by a gain factor to display the trace as if it were at high volume.
Tuning controls the pitch sensitivity in Composite Display mode. When tuning mode is turned off, the color of the displayed trace reaches its maximum redness or blueness when the pitch is a quarter tone away from its reference pitch. Turning Tuning Mode on multiplies the pitch sensitivity by five, so that the maximum redness or blueness shows when the pitch is one tenth of a half step, or ten cents.
Tuning may also be turned on or off using the Tuning checkbox on the Status display of the main window.
If Show Note Names on Grid is checked, the horizontal lines of the main grid are labeled with the note names whenever pitch is being displayed. Only the diatonic notes of the selected key are shown.
If Label Piano Keys is set to Letters, the note names A through G appear on the white keys of the piano keyboard whenever pitch is being displayed. If this option is set to Numbers, then the MIDI note numbers appear instead. (MIDI note numbers are useful for setting the Highest and Lowest notes on the Scale Tab.)
Preferred display length is the number of seconds of music that are initially displayed when Intonia is initialized or a new file is read in.
