Morph between four classic waveforms. Each shape can be randomized to create smooth random motion, sample-and-hold steps, and more. MIDI trigger modes and fade controls let it function as a one-shot attack-decay envelope or as a freely looping random source. ![](/files/ImrltxXaNiiM1dZdaGGq) *** ### 1. Main Controls **Rate.** Adjust the LFO rate in Hz or in BPM-synced values. **Rate Mode.** Choose whether **Rate** is set as a raw frequency or as BPM-synced divisions. **Randomize.** Set the amount of LFO randomization. Each waveform randomizes in a unique way. **Level.** Attenuates and/or inverts the LFO’s output. This affects every assignment that uses the LFO. **LFO Shape.** Choose sine, triangle, downward ramp, or square. With **Snap** off, shapes can be morphed continuously. **Shape Snap.** Enable snapping between LFO shapes. When off, the LFO shape morphs smoothly. ### 2. Trigger Modes Choose how the LFO responds to incoming MIDI notes: * **Free.** Always synced to the DAW’s timeline position and does not respond to MIDI. * **Trigger.** Resets on incoming MIDI, then loops continuously. * **One-Shot.** Resets on incoming MIDI and plays through once per note. ### 3. LFO Display Shows the real-time LFO position and shape based on the current settings. ### 4. Display Control **Phase.** Adjusts the LFO’s phase offset. In **Free** mode, it offsets the phase relative to the DAW’s timeline position. In **Trigger** or **One-Shot** mode, it sets the starting point when the LFO is triggered. **Fade.** Sets how quickly the LFO fades in or out when triggered by MIDI notes. This is available only in **Trigger** or **One-Shot** modes. A value of 0 disables fading. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://manual.minimal.audio/evoke-manual/modulation/morphing-lfo.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
