Some of them are not possible in tracker arp commands because they go above 3 or 4 notes (depending on which trackers arp commands you use). Some of them go beyond F semitones but I'll write the intervals in hex anyway for brevity and relevance to tracking.
C6/9 - C, E, A, D - 0, 4, 9, E
C13 - C, A#, E, A - 0, A, 10, 9
FMaj9#11 - F, G, B, C - 0, 2, 6, 7
Bb11 - A#, D, F, G#, C, D# - 0, 4, 7, A, E, 11
Fm13 - F, G#, C, D, D# - 0, 3, 7, 9, A (for this one I don't see how "/Bb" applies).
I'm all for music theory discussion on cm.org; we don't get enough of it imo.
Fm13/Bb simply means, Fm13 over Bb. So, the Bb would be our base note, but Fm13 would be played over it.
You seem to be conflating what a 'scale' and a 'key signature' is. A scale is a set of notes, where as a key signature defines the tonality of the music. Using the C major scale is not the same as 'being in C major.'
As roman numerals, you'd write Protodome's passage as:
In C major: I6/9 -> I13 -> IV9#11 -> bVII11 -> iv13/7 or bVII13*
*(I'm not quite sure about that last one. Fm13/Bb can alternatively be voiced as Bb13 as they contain the same notes... I think.. I am not great at 13th chords admittedly Protodome or some other music theory buff here could clarify me on this one).
But yeah, the B-flats, A-flats and all other notes that are not within the C major scale would be written in as accidentals.
You only change key signature/tonality in a piece of music if a new tonal centre is established (so if it's clear that a passage of music has well and truely resolved to a new key).
Lastly, whether or not a note is written in as a flat or sharp depends on the key signature we're in and the function of the chord.
(To give a basic example, the chord C7 would be written in as C, E, G, Bb. The B, ie, the '7th degree' is flattened in this case. C7 chords often resolve to F. If we're in C major (and the next chord is F major), the Bb would be written in as an accidental as we haven't fully modulated yet). This can be confusing to tracker musicians who haven't studied music theory because everything in a tracker is in sharps C, E, G, A# (on sheet music anyway) would be incorrect because, even though the tones are the same and it sounds the same as a C7, the A# causes it to spell Caug6 instead.
