MIDI Layers is an AUv3 MIDI plugin designed to allow sophisticated routing of MIDI data in hosts such as AUM or Cubasis. Have you ever wanted to play multiple instruments from a single master keyboard during a live performance? Would you like to be able to set up keyboard splits, crossfade layers or create an ensemble of layered instruments? If you answered yes to either of those questions, then MIDI Layers may be your solution. Layers allows you to create up to 12 scenes, each with up to 127 layers, spanning your entire master keyboard. These scenes allow you to seamlessly switch between various layer mappings at any time during a performance. Each layer controls the MIDI output, which can be routed to one of MIDI Layers 16 output ports and 16 channels. So if you have 5 layers in your scene, each layer is able to divert MIDI key input to 5 destinations, allowing you to control 5 instruments from one master keyboard. Layers can overlap, meaning you can create an ensemble of two or more instruments. Layers can also have cross fades so that you can fade from one instrument to another across a specified range. You can also control the velocity curves of a layer if you need to emphasize note velocity at a certain set of octaves. Each layer can also be remapped so that you can target a different key range on the destination instrument. This allows you to have several single note layers that can target specific drum machine samples for instance. You can assign a song per scene, or have several scenes containing parts of the same song. Switching scenes is simple, using the on screen scene buttons, via AU parameters, or you can even add a special control layer to a scene which can then be triggered via your master keyboard. It is also possible to assign a Program Changes to a layer. When you switch scenes, each layer can fire off its own program change to your destination instruments. Each scene can be assigned its own scale, which enables you to play using only the white notes so say goodbye to wrong notes. Finally, layers can be assigned to mute groups, allowing you to quickly turn on/off groups of layers with a single key or button press. Features: ○ Up to 127 layers per scene. ○ 12 scenes per preset. ○ Supports 16 output ports and 16 channels. ○ Remote switching of scenes using MIDI or AU. ○ Supports layer mutes and mute groups. ○ Named scenes with large scene selection mode. ○ Supports scales per scene which can be played using white notes only. ○ Each layer can define a Program Change that is sent when scenes are switched. ○ Supports per layer velocity curve. ○ Supports per layer remapping of notes on output. ○ Each layer can have a cross fade settings assigned. ○ Definable Master Keyboard size (6, 7, 8 or 10 octave). ○ Scene and mute control layers. ○ Provides default custom layouts. Please Note: This product will not work with GarageBand since it cannot load AUv3 MIDI plugins. ## Key features - Up to 127 layers per scene - 12 scenes per preset - 16 output ports and channels - Remote scene switching - Layer mutes and mute groups - Scales per scene - Per-layer velocity curves ## Recent user reviews (7 of 7) All indexed reviews: https://appshunter.io/ios/app/midi-layers/id1640217767/reviews.md ### 3/5 — Can’t filter sustain pedal from a layer *2026-08-20* Very nice set of features. But when keyboard is split between something like piano and synth, you can’t filter out the sustain pedal from the synth layer from within this plugin. This was the primary reason i purchased the plugin. ### 5/5 — Kudos and Feature Request *2026-03-15* Fantastic and indispensable tool for controlling multiple synths in AUM from 1 or more controllers. One thing that would make a huge difference would be to expose the AU parameter for the Panic button. Being able to map a button on a controller to initiate Panic would be must faster and more reliable in a live situation than opening the plugin and pressing the button in the UI. ### 5/5 — Brilliant, A keyboard players dream 🏆 *2025-04-01* I can’t believe there are no new reviews for this amazing app, I have said all I need to say below, except for this- you really won’t know what you are missing until you try it for your self 👍 2 years ago. I have been using this app for a while now and I just have to say that Layers is incredible, many of my projects use 3 or 4 different synth apps as lead instruments, the cross over from one synth app to another using just one keyboard and playing all parts in the same key area is seamless without any notes cutting off as you would normally get by just using Program Change using just one synth, no need for keyboard zones. You won’t realise how useful this app is until you have used it. 17th Oct. A MASSIVE thank you to Paul for his dedication in adding a new “ALL MUTES OFF” feature that I requested, Midi Layers just gets better and better ⭐️⭐️⭐️⭐️⭐️ 1st SEPT. As soon as I saw Paul’s YouTube demo of Midi Layers and what it is capable of, I purchased it without question. At first it took a little while to get into it in Cubasis3, but once I played around with it I soon realised what a fantastic useful app this is. Paul must have an amazing brain to produce an app of this calibre, he also has a knack of creating apps that we didn’t think we would need, but wow, we need them for sure, I wish this technology (and Paul’s apps) were available during the 90’s 👍 Thanks Paul ### 4/5 — Great app and more to go *2025-02-13* Great app. My hardware keyboard logistics seems to be gone. However modulation wheel and damper pedal from physical controller seems not to work. Hope those to be solved in the coming version. ### 1/5 — Doesn’t work fully in Cubasis *2024-08-05* App does not work fully in Cubasis. Wasted money. It was designed for AUM. Only a few of the features are available in Cubasis. Developer needs to be more honest in his description. ### 5/5 — Brilliant, just Brilliant. *2023-02-22* I have been using this app for a while now and I just have to say that Layers is incredible, many of my projects use 3 or 4 different synth apps as lead instruments, the cross over from one synth app to another using just one keyboard and playing all parts in the same key area is seamless without any notes cutting off as you would normally get by just using Program Change using just one synth, no need for keyboard zones.

Make sure the settings are set to send CC for volume. Make sure you have saved a snapshot to that scene, and ensure each layer is assigned to a unique group. NOTE: This change allows you to configure a scene to change instruments as well as volume and pan when the scene is initially selected. ### 1.05 — 2022-10-17 Fixed an issue processing CC layers in the correct order. Fixed a possible crash when selecting beyond the layers range after a deletion. You can now use CC 0 to unmute all layers. A control layer no longer passes notes to lower layers. Position the layer below all other layers if you require pass through. Fixed an issue where layer names don't quite fit in a layer, we no longer get truncated names. ## Apps similar to MIDI Layers | App | Rating | Price | Category | | --- | --- | --- | --- | | [ANALOGyGR](https://appshunter.io/ios/app/analogygr/id6746485545) | 4.7 (10) | $2.99 | Music | | [ANALOGyX1](https://appshunter.io/ios/app/analogyx1/id6745753877) | 5.0 (8) | $2.99 | Music | | [Pure Strings Instrument & AUv3](https://appshunter.io/ios/app/pure-strings-instrument-and-auv3/id6743003730) | 4.7 (51) | $29.99 | Music | | [lfoch](https://appshunter.io/ios/app/lfoch/id1665885755) | 4.4 (9) | $3.99 | Music | | [SploshBox](https://appshunter.io/ios/app/sploshbox/id6744564269) | 5.0 (1) | $1.99 | Music | | [ANALOGyXS](https://appshunter.io/ios/app/analogyxs/id6745030342) | 4.9 (16) | $2.99 | Music | ## More apps by 4Pockets.com - [Meteor Multitrack Recorder](https://appshunter.io/ios/app/meteor-multitrack-recorder/id417726727) - [Tone Generator Ultra](https://appshunter.io/ios/app/tone-generator-ultra/id514273546) - [PocketRTA Ultra](https://appshunter.io/ios/app/pocketrta-ultra/id514903914) - [StompBox Band](https://appshunter.io/ios/app/stompbox-band/id845046209) - [Audio Toolbox](https://appshunter.io/ios/app/audio-toolbox/id1353387223) - [Audio Compressor AUv3 Plugin](https://appshunter.io/ios/app/audio-compressor-auv3-plugin/id1426387457) All apps by 4Pockets.com: https://appshunter.io/developer/370131860 ## Related topics [mozaic plugin workshop](https://appshunter.io/ios/topics/mozaic-plugin-workshop) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
