With hundreds of MIDI tracks triggering a large sample palette, it would be priceless to designate non-pitched tracks (drums, perc, loops etc.) as immune to transposition. That way the user could easily “select all” within a range and transpose at will, without the non-pitched tracks getting messed up.
For now, I’ve created a fairly elaborate PLE / Macro workaround, but it would be much more elegant as a built-in feature. Possibly a MIDI plug that filters transposition?
Or, extending the “Lock” functionality to specifically include transposition?
