.52 Chord Editor is broken

[Saga Musix]

Full Version:
OpenMPT v1.17.02.52

Has the bug occured in previous versions? If yes, please specify version(s): (This option is optional, and doesn't need research. But in case you know...)
Maybe since split keyboard mode was introduced. Does work correctly in MPT 1.16


Description of the bug:
The chord editor's "C-0" base key (and all other base keys of course) is always a C-0 (or C#0, D-0, etc) in the pattern editor. However, 0 should be the base octave on the keyboard (e.g. 4), 1 should be base ocate +1 and 2 should be base ocate + 2. It was like that in MPT 1.16 and was maybe broken when the split keyboard mode was introduced.


How to reproduce (step by step description):
Try to enter any chord from the chord editor.

Fixed in OpenMPT 1.17.02.53
