If I take some data files from music extractor and change the precision of the floating point numbers, e.g. from 15dp to 8dp, some numbers are so small already that they get rounded to 0.
When this happens, the following error periodically happens when training.
Is cleaner automatically applied to all items before passing through other filters, or should we define it explicitly in the project file?
