Thanks for responding. Yes, I realize that what you say is true however, that's only if you haven't created and saved a customized channel scheme into the program via the file I referenced in my opening post of this thread.

From the days when I used Cakewalk 3.0, I've always made my own MIDI files and I've always used the same customized MIDI channel setup for Cakewalk and Band in a Box... (When I learned that BIAB allowed permanent custom MIDI channel assignments)

So for many versions of BIAB, I've been able to save my custom channel assignments into a special file titled, "MySETUP.DK" which appears when you click the "SAVE" button located in the bottom row of buttons in the Channels MIDI Settings Window. (pictured in the graphic of this thread's parent post)

BIAB always uses this "MySETUP.DK" as its "new default" channel setup scheme so that, upon each new opening of the program, my customized channel choices are retained and reflected in the Preferences Channels MIDI Settings window.

The point I'm trying to bring out is this:

When setting up a new permanent or semi-permanent MIDI channel scheme, 7 of the 8 channel boxes under the channel column are being saved into the "MySETUP.DK", there is only a single channel box that is not getting written into the file... and that is the Piano box which continually reverts to channel 3.

Since each of the other 7 channel reassignments are saved, retained, and retrieved upon each new program opening, it seems like there is a "bug" of some sort with the Piano channel assignment because it is the only one where the new channel assignment is not retained.

None of us knows what all of us knows.
