Gyre

What it does

• Five waveforms, up to ring-mod rates

  Choose square, triangle, saw up, saw down or sine. The x0.25 to x100 multiplier pushes the LFO to ring-mod rates.

• Vibrato that holds its depth

  At 100% depth, FM moves the pitch about one semitone up and down at any LFO rate. A Hermite-interpolated modulated delay does the work.

• Stereo rotation on a sphere

  Drag on the rotation sphere to set the centre between -180 and 180 degrees, with a range of 1 to 360 degrees. The rotation keeps the energy constant.

• Phase offsets for tremolo and vibrato

  Set AM and FM to 0, 90, 180 or 270 degrees against the LFO, so level and pitch move together or out of step.

• Locked to the song position

  With sync on, the LFO runs one cycle per beat times the multiplier, and its phase follows the song position.

• Presets, A/B and undo

  20 factory presets, your own presets, A/B setups with copy, undo and redo, and a 75 to 200% interface. Changes are smoothed over 20 ms, so they don't click.
