LFOH!
An AUv3 modulation effect combining a shaped low-frequency oscillator with MIDI CC and audio-amplitude processing.
Consider for a compatible host's modulation workflow
Morphing waves, cycle shaping and sample-and-hold create more variation than a plain fixed oscillator.
Keep in mind: It only works inside an AUv3 host. MIDI routing depends on the host and exact plug-in configuration.
Inside the app

Good for
- Musicians already using a compatible host such as the named examples.
Consider alternatives for
- People expecting a standalone synthesizer or every host routing option to work identically.
Limitations & considerations
- Captured minimum: iOS 9.3.
- It only works inside an AUv3 host. MIDI routing depends on the host and exact plug-in configuration.
