• All ApeSoft products are top tier! ★★★★★
    Love all of the functionality of your apps! So useful for sound creation, field recording, music, experimental work, modular sound design & so much more! ————————————————————— Small recommendation or request would be to change the LFO / Accelerometer display area to be a little more clear. I figured it out but it might be confusing for some. Something like an XY box or shape might increase the visual appeal & simplify how the LFOs are used. Could have speed on X & position on Y with a pinch in & out to select the position range or something like this. Really love the app though just thought if you were to make any changes this could be an option 🙂

  • Great tonal control ★★★★★
    Top notch well designed total frequency control for sound engineers. Pretty sure it has good midi, but it keeps me busy enough already manually exploring it's sensitive complex options.

  • Amazing app! ★★★★★
    Incredible peak multi-filter implementation. If you are sick of standard high/low-pass closings/openings in your FX here is a new universe for you to explore.

  • Apefilter truly the best on AppStore ★★★★★
    The only other filters that come close are Auria Pro plugins, but this is more fun. The apps by this developer get updated regularly and are extremely well thought out, raising the standard for the quality of iOS music-making in general.

  • One of my favorite FX apps ★★★★★
    Great app for modulating synths and other iPad music apps. The LFOs make it a real peach to use. Fantastic.
    By MusicInclusive LLC for Version 1.4.2
  • Solid Effect with Link Support ★★★★★
    The app works as advertised and has all of the options you'd want. It's an excellent way to change up your sounds in sync with other Link sources. The developer updates the app regularly so it works with the latest iOS and utilizes updated sound tools such as Audiobus, MidiBus, document picker, and Link.

  • Also very customizable ★★★★★
    As far as filters go, you can order a steak or you can order a fillet. This one is a fillet I can assure you. The amount of control you have is amazing. Each time I open this app it guides me through a different sonic terrain.
    By Long words for Version 1.3
  • Simply awesome ★★★★★
    At first it may seem like your average filter until you really understand and utilize what this thing can do. Spend a bit of time and really listen to what you're trying to achieve. It's probably the best ipad filter and I'd put it up against some the filters I use in Ableton and Logic.

The graphical interaction provides a great tool to design an extremely precise and smooth frequency response by directly manipulating up to 36 Peaks Filters. The Spectral Grid compilers increase the complexity and coherence between the filters bandwidth space. You can create your pitch space by the way of four different criteria of construction by determining a pitches grid: Fibonacci, Harmonic, Geometric and Scalar.
