Learning guitar

[OldMoses]

Here's a screen shot of a C minor scale displaying the V chord Gmin notes in yellow. I haven't tried alternative scales, other than the modal stuff, but my scale algorithm should be able to accommodate them. The code uses a 12 element true/false byte array that I rotate in a manner similar to how bits are rotated with _ROL & _ROR. That happens in SUB RotArrayM. Each element of the array corresponds to a note in the chromatic scale. That way I just align the tonic notes in the note array and starting point depending on the mode, then iterate through the note array picking out those that align with true and rejecting the false ones. Just drop a couple of select trues from the byte array and you've got a pentatonic builder.
