I'm really mad at myself. After all those years of tracking, I discovered just a few days ago, and also just by accident, the popup-window with the Note Properties, activated by a double-click in a note-field of a pattern.
All those years of typing in codes, field by field, while this was available ...
Values can be set with a slider, which means one can see the Min and the Max, no matter which numerical system.
While exploring this, I tried if hitting Enter on the note-field was equivalent to double-click there. It wasn't.
But it caused a nice function : It is used to directly select the 'Main Instrument' of the Pattern Tab. Quite handy.
While still playing with Note Properties onscreen, I tried a keyboard-key to see if a sound came up. It didn't, but instead it appeared that the keyboard situation was changed in a very specific way. Instead of three rows of qwerty-kb to write the notes, suddenly only
keys present in an octave were valid. So A - G. If the note under cursor is an A, and one repeats pressing the 'a'-key, the whole
range of A-keys is passing by, all octaves, plus A# or flat. Quite efficient.
It would be nice to have a button or a shortcut in this pane, to playback the actual setting of the note.
