Roll the Dice:
... and a random chord progression will appear in the timeline.
The numbers below each chord in the progression refer to the number of "beats" the chord will linger for.
You can adjust the playback speed of the "song" using, um, the "Playback Speed" slider.
The "Rake Speed" refers to the speed of a single "strum."
The main chart areas.
Primary chords appear in the chart for the selected key. A good arrangement generally uses every-other chord from this row.
Secondary chords. This row mirrors the primary row, but contains chords that are suitable replacements for the chords directly above (on the primary row).
Alternate chords. The chords in this area of the chart represent a nice selection of complimentary chords for the selected key. Pepper these chords throughout your arrangement for subtle variances.
Fretboard Finger Chart
The small circles indicate where your fingers should be placed on the fretboard. The numbers represent which finger to use.
#1 - Pointer finger
#2 - Middle finger
#3 - Ring Finger
#4 - Pinky
As the progression changes, the fretboard chart changes just before a new chord is getting ready to play.
Strum Pattern Area
There are three modes for each strum, up, down and off. Cycle through each mode with a click of the mouse.
Add or remove strums using the small arrows to the left.
Export to Midi
Just above the progression is a button you can use to export a midi file -- allowing you to import your chords into your favorite DAW such as Logic, Cubase, Sonar, Protools and any other program that can handle midi files.
This feature makes building midi guitar chords a snap!
