This is one of the strong features of Denemo. It allows you to control whether C-flat or B-natural is generated, and it warns you if you inadvertently enter the wrong one by playing augmented and diminished intervals on a different channel. There has to be a default setting of course, and this is made when you set the key-signature - it chooses a range of notes centred on the key signature you chose. For C-major it will choose the range E-flat to G-sharp. You set the range you need either from a menu (Input->MIDI-> XX step sharper and flatter) where XX is the current sharpest/flattest note that will be entered) or via a key shortcut or via buttons on the MIDI-in controls where the complete set of 13 notes are displayed. The range is also displayed on the status bar. (You can also alter the range with the modulation control of your MIDI controller, but keep off that for now). > > I did go to an unfamiliar menu option earlier -- Educational -> Aural > training -> Identity Scale... and picked some option > > But I'm not sure that was the cause of it. > > Also, when I play the B-natural, and it is expressed as "C-flat", it > also SOUNDS different. yes, it is warning you that you are doing something weird (well, not *that* weird), namely entering a diminished or augmented interval. > My default is piano but it switches to > (jazz?)organ for the B-natural AND the next note I play after that, > whatever the next note might be (!?!). you would have to find an interval from C-flat to something that *wasn't* another diminished or augmented interval for it to go back to the piano channel. > Then goes back to the piano > sound, until I play the B natural again.... > > I changed the key signature to G, and some flattened/sharpened notes > (relative to the G scale) produced the organ sound, while others > didn't.

Use View->MIDI in Control and keep an eye on the set of input notes you have chosen If you don't want it to warn you about diminished/augmented intervals use the preferences to change the pitch-spelling channel to the same one you are using for the staff. (This business of choosing the correct name for C-Flat/B-Natural/A-double-sharp is called pitch spelling). Denemo is, I suspect, the most sophisticated notation program in the world for helping to avoid this error which plagues scores entered via MIDI. I haven't created a single error in the scores I generate since I implemented this. It is a bit disturbing to be reminded at every diminished and augmented interval, but far better than generating a horrible score.
