Song Mode¶

Song Mode is unique because it controls two things: Song Parts (arrangement) and Chord Progressions (harmony).

Entering Song Mode¶

Press Song to enter Song Mode. The Song LED will light up.

Song Parts (Buttons 1-12)¶

Song Parts are sections (intro, chorus, etc.) of your song where you can specify which patterns play on which tracks, and which track to mute.

Selecting Song Parts¶

Press 1 to 12 to select and queue a song part
The queued part will start playing after the current part completes
Hold Song and press 1 to 12 to select without queuing

Song Part Settings¶

Pattern Grid¶

The screen displays a 16-cell grid representing all tracks:

Each cell shows which pattern will play for that track:

Number (1-16): The pattern that will play
Empty: Track is muted for this part

Use ↑ / ↓ to change the pattern number. Press B to go to the bottom line of cells, A to go up

Song Part Settings (Bottom of Screen)¶

Press B to move focus to the bottom settings:

Setting	Description
Length	How many times the part repeats before allowing change
Chords	Which chord progression to use (13-16)
Link	Auto-advance to next part when complete, got back to queued part, or loop on the this part

Chord Progressions (Buttons 13-16)¶

The PGB-1 has four chord progression slots (13, 14, 15, 16).

Selecting Chord Progressions¶

Press 13 to 16 to enter chord progression editing.

Chord Settings¶

Each chord in the progression has:

Setting	Description
Root	The root note (C, C#, D, etc.)
Quality	Chord type (Major, Minor, etc.)
Length	Duration in steps

Adding Chords¶

Navigate to the last chord in the progression
Press → to go past the last setting
Press A to add a new chord

Removing Chords¶

Navigate to a chord
Go to the add/remove page
Press B to remove the chord

Random Generation¶

The last page offers random chord progression generation:

Use ↑ / ↓ to select a scale (Major, Minor, Modal)
Press A to generate a random progression
Press A again to try different progressions

Chord Progression Indicator¶

While playing, small dots and an arrow on screen show your position in the chord progression. This helps you time part changes to land on specific chords.

The indicator also appears in the Cpy/FX menu for timing live effects.

Tips¶

Use the random chord generator for inspiration
Use different chord progressions for different song sections
The bass track automatically follows chord root notes
Lead tracks use the arpeggiator over the current chord
Chords track is the only polyphonic track that plays full chords
