The design of the Editor is based on the principles of a Piano Roll, i.e. the time axis is positioned horizontally, and different points on the vertical line correspond to different pitches. Main window combines the spectrogram of the original musical piece and the recognized notes. This way TrueTone Editor enables visual comparison of spectrogram peaks (reflected by color) and notes. The upper Ruler displays time marks (in seconds) or bar numbers, and the bottom line represents current or selected noteMIDI parameters. TrueTone Editor also permits editing of a single MIDI file without the spectrogram ("MIDI only mode").
In the diagram, a section of the spectrogram can be seen in which two notes are displayed, the first of which possesses the clearly visible spectrum structure. The lower peak corresponds to the main tone, and the two upper peaks, standing an octave apart, correspond to overtones.
The Editor lets you edit notes visually, adjusting their pitch, duration and onset position. Particular behavior of the Editor depends upon the editing tools selected.
