Modulation

Modulation is the system that connects dynamic sources — audio, MIDI, LFOs, sequencers, OSC — to any parameter in any track or effect.

Almost every float or bool parameter in Arkestra can be modulated. This is how you create audio-reactive, tempo-synced, or performance-controlled visuals without manual tweaking.

How to map a modulation source

Right-click any parameter → Map to… — the context menu shows all available modulation sources.

Or drag from the source (e.g. an LFO in the Modulation panel) to the parameter target.

Modulation sources

Source	Description
LFO	Oscillator — sine, square, ramp, staircase, bounce, pulse, S&H, and more
Sequencer	Step sequencer with up to 16 steps
Audio	Kick, snare, hi-hat detector ranges (3 configurable bands)
MIDI CC	Any CC from any connected MIDI device
OSC	Incoming OSC values via UDP
Ableton Link	Tempo sync for all beat-synced LFOs and sequencers
Fader	Direct manual control (the default)

Modulation stack

A parameter can have multiple modulation sources stacked — they’re summed together. For example: base value set by a fader + LFO on top + occasional audio kick.

Open the Parameter Detail view (click the modulation icon next to a parameter) to see and manage the full stack.

Modulation scaling

Each modulation assignment has:

• Min / Max — the output range (maps the [0–1] modulation signal to [min–max] parameter range)
• Depth — scales the modulation amplitude
• Invert — flip the signal

This lets you map the same audio band to multiple parameters with different depths and ranges.
