Overview
Tremolo changes volume in a repeating pattern. It can add a gentle pulse to clean chords, create a hard rhythmic chop, or move the level differently in the left and right channels for a wide stereo effect.
Depth controls the amount of volume change and Waveform controls its
shape. With Tempo Sync set to Free Run, Rate sets speed in hertz. Set
Tempo Sync to Tempo Sync and Division replaces Rate as the timing control,
locking the pulse to Axion’s current tempo with straight, dotted, or triplet
values. In Mono Stereo Mode both channels use the same modulation. In
Phase Offset mode, Stereo Phase delays the right channel’s cycle relative
to the left. Output Level compensates for perceived volume loss or gain.
Tips
- For a traditional amp tremolo, use Sine, Mono mode, Depth around 50%, and a Rate between 3 and 5 Hz.
- For a tempo locked pulse, enable Tempo Sync and begin with Quarter or Eighth Division. Dotted and triplet divisions create less obvious repetition.
- For a hard chop, select Square and raise Depth. Use Output Level to restore the average volume if needed.
- For stereo movement, select Phase Offset and start at 90 degrees. Higher values make the channels alternate more strongly.
- Saw Up and Saw Down create directional ramps. They are useful for rhythmic effects that should feel as if they rise or fall into each beat.
