 It features the following modules:
 - `midi`: Functions for converting between MIDI note numbers and frequencies, transposing, etc.
+    - `get_midi_note_name`: Get the name of a MIDI note number.
+    - `get_midinote_from_name`: Get the MIDI note number of a note name.
+    - `note_name_to_octave_position`: Get the octave position of a note name, eg "D" = 2.
+    - `octave_position_to_note_name`: Get the note name of an octave position, eg 2 = "D".
+    - `to_frequency`: Convert a MIDI note number to a frequency.
+    - `transpose`: Safely transpose a MIDI note number, making sure it is within range.
 - `scaling`: Functions for scaling values between different ranges, among other things it includes conversions between db and amplitudes, linlin and linexp, etc.
-- `binaryops`: Functions for binary operations on numbers, like clip, wrap, fold, etc.
+    - `linlin`: Linearly scale a value from one range to another.
+    - `linexp`: Linearly scale a value from one range to another, but with an exponential curve.
+    - `dbamp`: Convert a decibel value to an amplitude value.
+    - `ampdb`: Convert an amplitude value to a decibel value.
+- `binaryops`:
+    - `clip`: Clip a value between a min and max value.
+    - `fold`: Fold a value between a min and max value.
+    - `wrap`: Wrap a value between a min and max value.
