Number Sequence

Generate a sequence of numbers and apply it to a tag — perfect for filling out Track Number.

The Number Sequence function sets tag values to a generated sequence of numbers. You can also add the sequence to an existing tag at any position. The sequence increments once per selected file — if you have 14 files selected, the sequence increments 14 times. This function is especially useful for quickly filling out the Track Number tag.
