When trying to pick out a bass line when trying to learn to play it I find SongMaster Pro especially useful for analyzing Bass lines.

Although it can be done in various DAWs (eg Studio One Pro), I find SongMaster Pro really simplifies the process with its clarity and straight on work flow.

When playing the Bass stem solo in isolation from the Midi view it shows the bass line very clearly with timing and all the note names for all notes, quite helpful since the screen is adjustable for large midi notes and names etc (can cover the whole screen if necessary).

If some notes are missing in the midi it can be extracted from the pitch view and included in the midi view by adjustment of the midi sensitivity controls.

And the spectrogram view shows were it all sits in the spectrogram.

It is a very clear view, easy to follow and play along with or to write down in music notation.
