0- confirm that "hide unused note rows" is OFF
1- record/write a midi "melody" that skips a note, but contains a range of notes
2- toggle "hide unused note rows" ON
3- select an existing note and transpose it to a non-displayed note range that exists between your highest and lowest midi note
4- ISSUE: the note displays at the top of the midi editor in your highest visible note row. it cannot be clicked on, but it can be lasso selected. it plays properly, and re-toggling "hide unused" fixes the improperly displayed note.
NOTE: sometime around ~7-11-16, "View: Hide unused note rows" was updated, so that notes being recorded into the midi editor would "update" the hidden/unhidden note rows. prior to this, you'd see behavior like the notes being transposed above. could this fix please be extended to transpose actions?
