How-To's and Can-Do's
This page explains how you can set up ChordMaps2 for specific playing situations.
You can explore melody lines in three different places.
1 - First, you can use the dedicated Melody Keyboard, the one located about a fourth of the way down the screen. This keyboard sends MIDI signals to the Melody Sound Channels (M1 or M2) if M1 or M2 is enabled in row 2 at the top. You can also send MIDI signals to the Additional Sounds (A1 or A2) if A1 or A2 are enabled in row 2 at the top and also enabled on the Melody Keyboard itself.
This means you can play, or layer, on the Melody Keyboard, up to four different sounds, either individually or in combination.
2 - You can use the Bass Keyboard, found at the bottom of the screen in Portrait mode (vertically in Landscape mode), as a second melody keyboard. (Note: you may want to shift the Bass Keyboard's Oct + - value up several octaves.) This keyboard sends MIDI signals to the Bass Sound Channel if B is enabled in row 2 at the top. (If B-12 is enabled, then the same note shifted down an octave will be sent.)
3 - Map 9 is a melody-playing map. When playing Map 9, the MIDI signals sent go to the Chord Sound Channels (C1 or C2) if C1 or C2 is enabled in row 2 (column 2 in Landscape mode), and if C is "on" at the lower left edge of the Chordmap Region. (You can also send MIDI signals to the Additional Sounds (A1 or A2) if A1 or A2 is enabled in row 2 (column 2 in Landscape mode) and both C and A are "on" at the lower left edge of the Chordmap region.)
Situations Where You Might Use This
There may be times when you would like to solo more than one instrument as though they were holding a conversation with each other. For example, you can set up a trumpet for sound M1 and play it on the Melody Keyboard, and you can set up a saxophone for sound C1 and play it on Map 9. (If you would like to add a third instrument, you can set it up to play on the Bass Keyboard as sound B.)
(You can also add set up sounds for M2, C2, A1, and A2, and switch them on and off as needed.)
Here are a few ways you can explore bass lines.
1 - The Bass Keyboard at the bottom edge of the screen (vertical in Landscape mode) is dedicated to playing bass lines. It sends MIDI signals to the Bass Sound Channel when B (or B-12) is enabled in row 2 (column 2 in Landscape mode).
2 - Chords played in the ChordMap Region will send the information for the bass note if B is enabled in row 2 at the top (column 2 in Landscape mode) and if B is "on" at the lower left edge of the Chordmap Region.
3 - Maps 1, 2, 3, and 4 each have bass-playing areas built into them. The bass-playing areas are darker blue or gray in color. The bass notes in each section are notes that work well with the chord displayed in that area of the map. These bass-playing areas can be used to improvise bass lines while you are playing that particular chord.
The ChordMap Region normally plays the bass note along with the chord.
The chord notes are sent to the Chord Sound Channels (C1 or C2), and can also be sent to the Additional Sounds (if A1 or A2 is enabled and if both C and A are "on" at the lower left edge of the Chordmap Region).
The bass information is sent to the Bass Sound Channel (which plays if B or B-12 is enabled and B is "on" at the lower left edge of the Chordmap Region).
You can choose to play only the chord or only the bass note, when a location in the ChordMap Region is touched, by turning B and C on or off at the lower left edge of the Chordmap Region.
Situations Where You Might Use This
Most of the time you will want a touch in the ChordMap Region to play both the chord notes and the bass note at the same time, but there may be some situations where you would like to determine what the chord notes and the bass note are going to be, but not play them all just yet. (For example, the bass note might be played first with the chord notes following.)
When you touch a location in the ChordMap Region, the chord notes and bass note are calculated for the new touch, but they are only sent out as MIDI signals if all the switches are enabled (the ones in row 2 in Portrait mode or column 2 in Landscape mode, and also at the lower left edge of the Chordmap Region). This means you can select whether you want the chord notes (or bass note) to sound right away or be stored in memory until one of the Repeat areas is touched. (The Repeat areas play chord notes or bass notes that are currently stored in memory.)
On the right edge of the screen, just below the Melody Keyboard, is a group of 44 locations with labels like 5-7, 5-1, 5-2, 5-3, etc. These locations play 2-note intervals.
If chord notes are currently sounding when the 2-note interval is played, the sounding notes will be replaced by the 2-note interval. However, the chord stored in memory, from the last touch in the ChordMap Region, will remain stored in memory.
Note: this area behaves a little differently than the Maps. The 2-note intervals send MIDI signals to the Chord Sound Channels (C1 or C2 if enabled), but turning off C at the lower left edge of the Chordmap Region will not silence the 2-note interval area, and switching "on" A at the lower left edge (if A1 or A2 is enabled in row 2 at the top) will cause the Additional Sounds to be played by the 2-note interval area, even if C is turned "off" at the lower left edge.
Some musical styles are characterized by a Bass - Chord - Bass - Chord pattern. You can experiment with this style by switching C "off" at the lower left edge. When you touch a chord location in the ChordMap Region, the chord notes will be calculated and stored in memory, but only the bass note will play. You can then play chord notes, either individually or in various combinations, by tapping locations in the Repeat areas.
The Repeat areas are sometimes indicated by the word "REPEAT" and sometimes by musical notes displayed on screen. An area that repeats the bass note will be labeled "BASS."
At the far left of the Melody Keyboard is a location labeled H M1 M2. Touching M1 in the upper part of this location turns on the Harmony Option for sound M1.
When the Harmony Option is enabled, harmony notes will be added to the note played on the Melody Keyboard. The harmony notes will correspond to the most recently played chord location in the ChordMap Region.
This same idea applies to the M2 location at the bottom of H M1 M2, and also to the H A1 A2 locations at the far right of the Melody Keyboard. When M2 is selected, harmony notes will be added to sound M2 on the Melody Keyboard. When A1 (or A2) is selected at the far right, harmony notes will be added to sounds A1 (or A2) if they are being played on the Melody Keyboard.
The Display Keyboard is an 88-note keyboard which shows the notes currently being sent out over MIDI. The Display Keyboard can also be played. There are 24 playable zones spread out across this keyboard.
When a chord is calculated as a result of a touch in the ChordMap Region, the chord notes are mapped up and down the keyboard to these 24 playable locations. You can tap the Display Keyboard in various places and hear individual chord notes played.
Normally, these notes are sent out over the Display Keyboard Sound channel, but if MM, which stands for "Mirrors the Melody," is enabled (at the far right edge of the Display Keyboard), then the notes are sent instead to the Melody Sound channels just as if the notes had been played on the Melody Keyboard. In this case, the Display Keyboard becomes an extension of the Melody Keyboard, but it only plays notes that are part of the current chord.
When the Display Keyboard has the MM option selected (at the far right), then the 24 playable zones mapped out across this keyboard will behave as if they were extensions of the Melody Keyboard. This means that if any of the H M1 M2 (or H A1 A2) harmony options are enabled, added harmony notes will be sent out when any of the 24 playable locations on the Display Keyboard are touched.
