midiLFOs is a MIDI controller app and AUv3 MIDI effect that sends MIDI modulation control data to other music apps and external synthesizers. It has four independent LFOs that send 7 bit MIDI CC messages in repeating Low Frequency Oscillating patterns. The LFOs can be the various standard shapes (sine, saw, triangle, square, sample and hold) but can also modulate each others amplitude and rate to create even more interesting shapes.
midiLFOs does not make music or sound by itself, it controls other MIDI capable synth apps and devices in your studio. You can use it to modulate the filter cutoff frequency of your favorite synth app, the pan position of the hi hats in a drum machine app, the feedback amount of a delay effect, or the pitch of an external hardware synthesizer. Or you can do all four at the same time.
- Four independent LFOs that send 7-bit MIDI CCs
- Easily configure CoreMIDI port, channel, CC# per LFO
- Use in other apps as a MIDI Audio Unit Effect
- Easily adjust shape, rate, offset, lag per LFO
- Modulate the rate and amount of an LFO using other LFOs
- Sync LFOs to MIDI clock or Ableton Link
- Map trigger, LFO rate, and modulation amount values to incoming MIDI
Designed to be easy to configure and use, midiLFOs gives you a quick to configure and easy to use MIDI LFO controller toy with extra features that also make it a useful pro music studio tool.
AUv3 support requires an AU host app that supports MIDI effects, such as AudioBus 3, AUM, etc.
Fixed AU startup crash with some devices / iOS version combinations.
Added visual display of current mod values from other LFOs on the mod sliders.
Expanded the range of the clock synced rate AU parameter to match 3.1.0 increase.
Ratings and Reviews
Awesome tool toy
I really love this app. The simplicity in the user interface makes using it easy and yet still reveals some fun complexities. The fact that it can handle clock inputs and CC control as well as modulate each other makes this app super flexible.
I wish the visual waveforms of the user-interface would more closely match the path of the output. I also wish that I could control the range values by pinching the waveform and sliding up and down to create an offset in the value range. I would also change the current feature named “offset” to “phase”.
Beats Bram Bos Rozeta LFO
MidiLFOs provides superior visual feedback compared to the Rozeta LFO. Another good sign is A.K. also took the trouble to supply a pdf help manual that moves beyond the level of 'This a knob. It is my knob. I turn the knob left and I turn the knob right. The knob goes from 0 to 10...'. I appreciate this since I do not have a history of using midi hardware and so I'm thankful for pertinent discussion/instruction/how-to on the subject of Midi as it relates to this software synth realm I have recently found myself enjoying.
Amazing for procedural music, as I like to call it since I come from video games lol. This thing is perfect for modular synthesis, in more traditional musical terminology.
If you know what you’re doing, you won’t regret buying this. And realistically, if you were looking for a MIDI LFO controller, yes you probably already know what you’re doing so just get it right now.
My main suggestions about what to combine with this app:
Step Poly ARP:
turn the MIDI CC into notes somehow: I use the app Mozaic with a custom script I wrote, then quantize that to a scale and run it through an Arpeggiator.
Super simple to send midi in interesting and dynamic ways, AUM and AudioBus lock you into a very linear workflow especially when setting MIDI up which can lead to slow innovation and creativity.
