Instruments and Effects

The Instruments tab is where you build the track list, choose sounds, balance the mix, and add effects. Every track in the song is managed here.

---

Track management

• Add Track creates a new empty track.
• Collapse All opens or closes track panels so you can see more tracks at once.
• Each track header includes a collapse control, color assignment, and remove action.

Use clear names such as Lead Synth, Bass, Piano, or Hi-Hat. Track names and instrument choices help the AI understand what each track should do.

Track identity

Control	Purpose
Name	Label shown in the overview, instrument list, and generation targeting.
Drums	Marks a track as percussion on MIDI channel 10.
Family	Filters General MIDI programs by broad instrument family.
Program	Selects the General MIDI instrument for melodic tracks.
Drum Kit	Selects the percussion kit for drum tracks.

Mixer controls

• Mute silences a track without deleting notes.
• Solo plays only soloed tracks.
• Volume controls track output level.
• Pan positions the track left or right.
• Soundfont override lets one track use a different soundfont from the project default.

Per-track groove override

Each track can follow the project groove or use its own groove setting.

• Use Project follows the Project tab groove.
• Straight disables swing on that track.
• Swing 8ths applies eighth-note swing.
• Swing 16ths applies sixteenth-note swing.

Use this when drums need one swing amount but bass or melody should stay straighter.

---

FX rack

Each track can have a chain of audio effects. Effects process top to bottom during playback and export.

• Click Add FX to add an effect.
• Toggle an effect off to bypass it without removing it.
• Delete an effect to remove it from the chain.
• Effect settings are saved with the project.

Effects reference

Effect	What it does
Filter	Cuts or boosts frequency bands with low-pass, high-pass, or band-pass modes.
Reverb	Adds room or hall ambience.
Delay	Adds timed echoes for rhythm or space.
Drive	Adds saturation or distortion.
Chorus	Thickens sound with pitch-modulated copies.
Compressor	Controls dynamic range and evens out peaks.
Limiter	Prevents output from exceeding a set ceiling.
Noise Gate	Silences signal below a threshold.
Phaser	Creates sweeping phase movement.
Bitcrush	Adds lo-fi digital degradation.
Low Shelf	Boosts or cuts low frequencies.
High Shelf	Boosts or cuts high frequencies.
Peak EQ	Boosts or cuts a focused frequency band.
Pitch Shift	Transposes audio up or down by semitones.

Filter, Reverb, Delay, Drive, Chorus, and Compressor support Motion controls: automatic note-triggered animation of key parameters.

---

Motion controls

• Motion shape sets the curve, such as Decay, Attack, or Swell.
• Motion amount controls movement intensity.
• Motion rate controls how quickly the animation completes.

Use motion when every note should have an animated character, such as a bass note that starts bright and darkens over its duration.

Automation and modulation

Automation changes track parameters over the song timeline. Modulation changes parameters per note.

Use Automation when a parameter should change at a specific song moment, such as opening a filter at bar 9.

Use Modulation when each note should share the same animated behavior, such as every note triggering a filter decay.

Both can be used on the same track.
