Now I have the code in this way.I have added some details…
On the line 101I have added your loop,within the function explode_pitches, below:
local next_note = song:pattern(notes[i+1].pattern):track(dest_track):line(notes[i+1].line):note_column(dest_column)
next_note.note_value = 120
next_note.delay_value = notes[i+1].note_column.delay_value
end
end
end
end
--song:delete_track_at(song.selected_track_index) -- delete original track
local first_octave_track = renoise.song().selected_track_index + 1
local track_index = first_octave_track + 9, first_octave_track, -1
local was_empty = true
for _, pattern in ipairs(renoise.song().patterns) do
if not pattern:track(track_index).is_empty then
was_empty = false
end
end
if not was_empty then
delete_track_at(track_index +1)
end
end
The code does not error, but does nothing.I understand that the location of the loop is correct,just after build and sort notes by octave…
Is this correct? :
local track_index = first_octave_track + 9, first_octave_track, -1
Isn’t it just more tedious navigating thru these columns? I could possibly see some benfit if you’re inclined to really dive into dense humanized midi recordings.
