Scale and Chord Guides
Here are some of the most commonly used scales, modes and chords,
and their associated ATR-1a settings. All spellings use sharps because the
ATR-1a software uses sharps to describe all accidentals (the black notes
on the keyboard).
Scales/Modes reference chart
While the major scale needs no introduction, the others might need some
explanation. For example, the difference between the natural and har-
monic minor is only one note, the seventh scale degree. The natural minor
uses a...

MIDI System Exclusive Message Formats
In the explanations, below, braces < > are used to represent enclosed MIDI
data bytes. Concatenated data is shown by < > < >. Names are also enclosed
in braces as symbolic representations defined further into the explanation.
Values are decimal unless an H is used to denote Hexadecimal values.
For example, the MIDI bytes to select song mode for DEVICE NUMBER 3 are:
F0H, 0, 1, 26H, 3, 1, F7H.
