help synth LFOs

An LFO (Low Frequency Oscillator) is an oscillator not used to make sound but to change another parameter like gain or pitch.

This is how the GridSound gain LFO looks like:

The graphic is showing the LFO's wave with some black lines representing the beats. All the time values are related to the BPM of the composition.


  • 🅰️ gain and pitch are two tabs you can select to switch from the gain and pitch LFOs.
    Each tab has its own toggle button to activate.

  • 1️⃣ Delay: The time (in beat) before the LFO starts.

  • 2️⃣ Attack: The time (in beat) taken for the LFO's amplitude to reach 100%.

  • 3️⃣ Speed: How many time the wave is repeated in one beat.

  • 4️⃣ Amplitude: How strong the effect will be.

  • 5️⃣ Amplitude sign: This is used to reverse the wave, the top goes to the bottom and vice versa.

  • 6️⃣ Wave: The shape of the LFO.

  • 7️⃣ The graphic is showing the LFO's wave with some black lines representing the beats. All the time values are related to the BPM of the composition.
