TS-MIDI Editor allows you to quickly and effectively correct the results of the automatic recognition (for example, by TS-AudioToMIDI). The editor is designed similarly to a Piano Roll, i.e. the time axis is located horizontally, and different positions on the vertical line correspond to different pitches. Among the functions of TS-MIDI Editor, there are functions like adding/removing notes; changing pitch and duration; playback of the result. Furthermore, Note Editor allows saving intermediate results as special files (.tsme). The editor lets you play a fragment of the MIDI file, therefore, allowing you to remove erroneous notes, which could have appeared during the recognition process, piece by piece. For your convenience, the editor has several operating modes. In the editing mode ("Edit Tool") you can move the notes, change their duration, create new notes ("Create notes" option) and also "glue" together the notes, erroneously divided by the automatic algorithm ("Glue" Option). In "Delete Tool" mode, you can quickly remove the unnecessary notes at once. At any time, you can play the entire composition or the assigned fragment, at a normal or slow speed. One of the useful TS-MIDI Editor features is the ability of temporarily muting the notes. In this case, the muted notes are displayed as colored boxes and do not sound at playback. That way, you can evaluate the editing results, with some specific notes muted or enabled. Additional editor features include the scale selection, editing of the color scheme ( "Edit Color Scheme"), editing a specific note's attributes separately (velocity, duration, channel, track, patch) as well as the attributes of the new notes by default and the MIDI file's properties. You can cancel any number of the produced manipulations at any time (Undo).
