Great app

Does what it says

Bug Found in exposed AUv3 parameters

The exposed parameters (eg. in AUM) respond to midi mapping externally but the changes don’t propagate into the plugin.

Great app

Lightweight. Very useful. UI is a little clunky but then I’m not gonna write a replacement myself.

Don’t fooled by the GUI

It doesn’t actually show you the LFO signal. It’s just an image. Kinda makes using this with cross LFO modulation useless. You’re better off with some like lfoh! Would have liked to return but the useless UI wasn’t a sufficient return reason. One star.

Perfect

Wish I could attach this directly to several hardware boxes. It’s perfect/brilliant. Wish every LFO I used was replaced by this app. Easy, quick with just enough depth/futzability.

FAQ

What is midiLFOs used for?

midiLFOs is a MIDI controller app and AUv3 MIDI effect designed to send MIDI modulation control data to other music apps and external synthesizers. It generates repeating Low Frequency Oscillating patterns to control parameters like filter cutoff or pan position.

Does midiLFOs make sound on its own?

No, midiLFOs does not produce any sound or music by itself. Its sole function is to control and modulate parameters within other MIDI-capable music applications and hardware synthesizers.

What kind of LFO shapes does midiLFOs offer?

midiLFOs offers standard LFO shapes including sine, saw, triangle, and square. It also includes a sample and hold shape, and allows LFOs to modulate each other's amplitude and rate for more complex waveform generation.

How can I use midiLFOs with other apps?

midiLFOs can be used as an AUv3 MIDI effect within compatible AU host apps like AudioBus 3 or AUM. It allows you to easily configure CoreMIDI ports, channels, and CC numbers for each LFO to control parameters in other music apps.

Can midiLFOs sync with external tempo sources?

Yes, midiLFOs can sync its LFOs to MIDI clock or Ableton Link. This ensures that the modulation patterns stay in time with your other music production tools and applications.
