Select a preset to replace the arrangement. The tool asks before it replaces your edits.
A manual tempo change during playback starts at the next bar. A speed-up change starts at a loop boundary.
The count-in plays before a fresh start. It does not repeat with the loop.
Chord names are finger shapes. The capo raises the sounding pitch.
Select a common Swing value. Edit swing: in the arrangement for another value.
Speed up starts at half of the current tempo, rounded to the nearest 5 BPM. It uses the current tempo as the target.
Arrangement format
Use one chord bar and one strum bar for each bar after repeat expansion.
Use count-in: 0, 1, or 2 after the BPM directive.
Use tempo-ramp: off after the count-in directive. To increase the tempo, use a value such as tempo-ramp: +5/2/120. This value adds 5 BPM after every 2 completed loops until it reaches 120 BPM.
Use capo: 0 for no capo. Use a value from 1 through 12 to raise the sounding pitch while you keep the written chord shapes.
Use swing: off for straight timing. Use a whole number from 50 through 75 to set the first eighth note's share of each beat. Use swing: 67 for an approximate two-to-one triplet feel.
Use D for a downstroke, U for an upstroke, and - for no strum.
Add 2, 3, or 4 to limit the string count. A downstroke starts with the lowest-pitched playable string. An upstroke starts with the highest-pitched playable string.
Add P for palm mute. Add X for a dead strum. Add ! last for an accent.
Write tokens in this order: direction, string count, articulation, accent. Example: D3P!.
Use Chord@N for a chord change at slot N. The change occurs before a strum at the same slot.
Use xN after one bar to repeat that bar N times in total.
Number notation
A number arrangement requires original-key:, key:, and notation: numbers before capo:. The original key is a reference. The key directive sets the sounding key.
Use mode-relative degrees from 1 through 7. Add a colon and quality when required, such as 6:m or 5:7. Use 1/3 for a numbered bass note.
In number notation, changing Play with changes the guitar shapes. It does not change the sounding key.
original-key: Bb major
key: Bb major
