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. ### 2/5 — Great app *2024-07-29* Does what it says ### 2/5 — Bug Found in exposed AUv3 parameters *2024-07-27* The exposed parameters (eg. in AUM) respond to midi mapping externally but the changes don’t propagate into the plugin. ### 4/5 — Elegant utility *2016-09-20, version 1.3* I never needed this app. I had two other apps that did its job quite well (oscilab and different drummer) but neither did it with the grace of midilfos. It may lack Link which is a shame but it sits in the multitasking sidebar very nicely and interacts very nicely with all my favourite synth to take them to another level. Small foorprint, easy to use, great user interface and a host of extra functions that inspire you to modulate your knobs to your hearts content. Im happy with my purchase. Link would be nice though ;/ ### 4/5 — Great when it works *2015-08-22* Works great to control egoist running as an iaa instrument in cubasis or gadget on my ipad air. On my ipad mini though it crashes when cubasis is running. Glad it works on one as it is perfect for my process. ### 5/5 — Great app *2024-07-15* Lightweight. Very useful. UI is a little clunky but then I’m not gonna write a replacement myself. ### 5/5 — Perfect *2021-03-13* 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. ### 5/5 — Brilliant *2020-10-29, version 3.1.1* One of my most used AUs. Easy to use, flexible, reliable, and undeniably useful. ### 5/5 — Great app, needs MIDI Learn *2020-07-08* Like it but would love MIDI learn to auto assign incoming cc/nprn to the selected LFO. That would be hugely helpful to avoid having to dig thru manuals to find model specific CC#s. ### 5/5 — Beats Bram Bos Rozeta LFO *2019-12-06* 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. ## Most praised reviews (4 highest-rated) ### 5/5 — MASSIVE! *2019-09-27* 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. ApeMatrix: 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. ### 5/5 — Great AUv3 Update *2019-09-13* A nice update which allows you to run multiple instances for even more MIDI modulation LFO control of your setups. ### 5/5 — Awesome tool toy *2017-09-29* 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”. ### 5/5 — Works great with TE OP-1! *2015-12-20* The TE OP-1 does not have good LFO beat sync, so this app is a life-saver. Tip: Disable USB charging on OP-1 if connecting directly to iPhone. Otherwise, stuttering occurs (due to hardware, not app). --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
