The Screen Explained - Part 2
The areas and zones on the ChordMaps2 screen are described here. (Portrait mode)
The ten maps (numbered 0 to 9) are selected in the left column.
Map 0 is designed to play power chords (root, fifth, octave).
Map 1 explores chord progressions using I, ii, IV, and V chords.
Map 2 explores chord progressions using I, IV, V, and vi chords.
Map 3 explores chord progressions using I, ii, iii, IV, V, and vi chords.
Map 4 explores Blues progressions.
Map 5 plays three-note (root, third, fifth) progressions in major and minor keys, including secondary chords.
Map 6 plays iim7, V7, IM9, I6 around the circle of fifths.
Map 7 explores ii, V, I variations (with IV, iii, and VI) around the major and minor circle of fifths.
Map 8 plays tenth chords (root, fifth, tenth) in major and minor keys, and includes secondary chords.
Map 9 is a melody-playing map. (Note: these notes will be played by the chord sounds rather than by the melody sounds.)
A - When A is on, Additional Sounds will play when a chord location in the chordmap region is touched. (Note: A1 or A2 must be enabled in row 2.)
B - When B is on, the bass sound will play when a chord location in the chordmap region is touched. (Note: B must be enabled in row 2 above.)
C - When C is on, the chord sounds will play when a chord location in the chordmap region is touched. (Note: C1 or C2 must be enabled in row 2.)
Hold - When Hold BC is on, the bass and chord notes playing will be sustained until new bass or chord notes are played. When Hold MD is on, notes played on the Melody and Display Keyboards will be sustained until a new note replaces the one currently playing.
The chord-playing region of ChordMaps2 is divided into three areas. The largest area is called the "Chordmap Region." This is where Maps 0 - 9 are displayed and played.
To the right of the Chordmap Region are two other areas that play notes by sending signals to the Chord Sound MIDI Channels. The upper area plays two notes at a time in intervals of thirds, fourths, fifths, or sixths. (Note: when these two-note interval areas are played, the chord notes currently playing are replaced by the two-note interval.)
The lower area repeats chord notes as determined by the last touched location in the Chordmap Region. These repeated notes can be single notes from the chord, or groupings of notes from within the chord. The lower section can also repeat the most recently played bass note.
The Bass Keyboard, like the Melody Keyboard, is designed to be played one note at a time. It is a transposing keyboard, meaning the user can play the major scale on the white notes, starting at 1 and going up to 7, regardless of which key is currently selected at the top edge of the screen. (If it is desired to play the Bass Keyboard without the transpose function enabled, it can be turned off at the left edge by touching the location that reads "TR X." (transpose off)
The Octave + and - buttons shift the Bass Keyboard up or down in one octave increments. (Note: this Bass Keyboard already represent very low notes on the keyboard, so the value of this variable does not go below zero.)
The 5 button adds chord notes playing a root and a fifth along with the bass note.
The C button adds chord notes playing an octave along with the bass note.
If both the 5 button and the C button are on, chord notes play root, fifth, octave along with the bass note.
The M button adds a melody note to the bass note.
The ? button shows the Onscreen Help, which provides a short description of the various parts of the screen. Touching ? again will turn off the Onscreen Help.
