Yass checks any of your input on errors. Errors are listed in the error window; there you can select them, obtain details, and choose to auto-correct them (if possible). Note that error detection itself does not modify your karaoke data.
These errors are checked when a song is opened:
- Transposed notes: Note heights are outside the range [-12,36] or the lowest note is above 12. You might not hear MIDI clicks.
- Missing end: The end tag E is missing.
- Metadata: tags, files, sorting (most of them can only be corrected in the song library)
- Misplaced tag: Please place comments in the header.
- Tag after end: Please place comments in a comment line with e.g. the CREATOR tag.
- Invalid tag: Use one of these comment tags: TITLE ARTIST LANGUAGE EDITION GENRE ALBUM YEAR CREATOR ID MP3 COVER BACKGROUND VIDEO VIDEOGAP START END PLAYERS RELATIVE BPM GAP LENGTH PREVIEWSTART.
- Unsorted comments: Please use the ordering above.
- Missing tag: A commonly used tag is missing (LANGUAGE, GENRE).
- File not found: The given file does not exist. The directory contains no possible matches.
- File not referenced: The song folder includes a file that is not specified in the header.
- No [CO] label: The filename does not end with [CO].jpg.
- No [BG] label: The filename does not end with [BG].jpg.
- No [VD] label: The filename does not contain [VD#…].
- Wrong video gap: The video gap does not match the [VD#…] in the filename.
- No videogap: The video filename includes [VD#…], but there is no VIDEOGAP tag.
- No [VIDEO] label: Please include [VIDEO] at the end of the directory name.
- Wrong filename: The song directory or some of its files do not follow the “Artist – Title” naming convention. Auto-correction preserves file extensions and comments in [brackets].
These errors are checked whenever you modify a note:
- Overlapping notes: Either this note starts too early or the note before lasts too long.
- Out of order notes: Notes are not sorted by their timestamp.
- Touching notes: No spacing between two notes. Players might find that difficult to sing. Auto-corrections shortens the first note.
- Uncommon golden bonus: The percentage of golden notes does not match with the maximum golden bonus. You can set the variance in beats from the ideal quota in the preferences.
- Early page break: Line disappears after less than 50 ms; users might be annoyed.
- Late page break: Next line starts after less than 50 ms; users can hardly catch up with the text.
- Uncommon page break: Text disappears or appears with unconventional timing.
- Page overlap: Page break overlaps notes.
- Too much spaces: Two or more spaces.
- Uncommon spacing: Please place spaces in front of text.
- Line overflow: This line might not fit on screen.
- Empty line: Please do not insert empty lines.
- Invalid line: Lines must start with one of these symbols: #:*F-EP.
- Line cut: missing parameters.
A few critical errors are automatically corrected while the karaoke data is loaded. In contrast to error detection (described above) changes will become permanent as soon as you save the files.
- Lines with missing spaces after characters “:-F*” are completed and loaded correctly.
- Text after comment symbol “#” or end symbol “E” is trimmed to remove leading/subsequent spaces.
- Likewise all redundant spaces between numbers are removed.
- Decimal symbol “.” is exchanged with comma “,”.
- The boolean “true” is exchanged with “yes”.
- Invalid lines not starting with “:-F*” are converted into comments starting with “#”.
You can trim page breaks to repair early/late page breaks, and optionally also uncommon page breaks.
- In the error window, select and correct a specific page break error.
- Press Ctrl-t to trim all page breaks
- Specify in the preferences if you want to trim automatically while editing.
In the preferences, you can set the minimum number M of beats before+after pagebreak manually. Default is M=0, which sets pagebreaks automatically using these trimming rules for pauses between page breaks:
- Less than 2 beats: break immediately.
- 2-8 beats: break 2 beats before new line.
- 9-12 beats: break 3 beats before new line
- 13-16 beats: break 4 beats before new line
- More than 17 beats: break after 10 beats
- More than 2s: break after 1s.
- More than 4s: break after 2s.
These rules do not ensure a smooth transition between levels; you might experience jumps when dragging notes in automatic-trim mode. Contact me if you think you have developed a better algorithm.
