@dmstar1956 These means that the loops use the notes of the basic chords of the C-Major scale, usually major chords (capital letters) or minor chords (small letters). You can use the pitchshifting feature to pitch the loops up and down in case you want to play in anther scale. Additionally, you can use the Vocal Tune effect to modify individual notes of loops. This will work on monophonic loops where only a single note is played at a time. Of course, you can also use it on loops that play chords, maybe you'll get some interesting results, but you cannot change individual chord notes.
Since the first chord entered is C-major, shouldn't all of the subsequent pitches, if arranged in order from 1-7, be the major chords in the key of C-major? What determines what chords or notes correspond to the 7 pitches?

In the past the chords were usually defined in the BPM.inf text file inside the Soundpool folder, and additionally in the description.xml file inside the Soundpool folder. The program only reads the values inside these files. There could be any value in there.

No. The pitches should follow the definition in the inf or xml file in the Soundpool folder. But, I recall that nearly all Soundpools use the same pitches, but there are a few exceptions. So you can usually mix loops from different Soundpools and as long as they have the same pitch you shouldn't get clashing notes.
And, of course, you can mix und combine loops like you want, without caring about it sounding "correct". This can be useful to give your compositions some 'spicy' sections.
@dmstar1956 C, d, e, F, G, a, A# will give you information about the chord notes used in the loop.
So pitch 1 = C Major means that most likey the notes c,g and e are used in the loop. But the loop can also have other notes as well or only c notes or only c and g notes. It depends.
A pitch 1 loop from another category or Soundpool will also most likely have c,e and g notes. So they will likely sound nice together.
If you have a pitch 1 loop you can play the C Major scale to it without sounding out of tune because it's a C Major chord.
The C Major Scale has steps (tones) and half steps (semitones) ie C, C#, D, D#, E, F, F#, G, G#, A
Actually, with the addition of A# and B, that is the Chromatic scale of C.
With reference to the question raised by @dmstar1956 about C d e F G A#: I can't explain why the A# is there but I might speculate it's because the other capitalised letters are the root notes of major chords in C, whilst those with lower-case letters are minor chords in C.
But who knows why Magix chose those "names" to display???
