## What is DigiKeys AUv3 Sequencer Plugin?

DigiKeys is an AUv3 compatible MIDI sequencer plugin for AUM or other AUv3 compatible host applications.

DigiKeys is a pattern based sequencer which can be used to drive either external MIDI based AUv3 instruments, or the internal sample based audio engine. It can also be used as a 16 channel multi-timbral sound source accepting MIDI data on each of the 16 MIDI channels and routing to 16 internal instruments. This flexible design allows you to experiment with pattern based song construction using the DigiKeys sound engine, then map to external MIDI based synth engines once an idea needs expanding. The program was created specifically for AUM, but should function fine under any DAW of your choice (routing options permitting). The advantage of AUM is its unlimited routing flexibility, and the ability to split MIDI output in order to feed multiple AV3 sound sources

DigiKeys allows you to create looped patterns which can later be chained into songs. Each pattern has 16 tracks (one for each MIDI channel) which can be up to 32 steps in length. Each track can have its own playback speed, transposition and effects routings. You can chain up to 256 of these patterns together into a song, and since each song is tied to a scale, you can use the transpose function to quickly create chord changes without needing to redesign your patterns.

DigiKeys was designed to drive other MIDI compatible AUv3 plugins, but comes equiped with its own internal synth engine with over 100 custom presets. If you own the 4Pockets Chameleon sampler plugin, DigiKeys will auotmatically make those instruments available to you, so its easy to expand the library of instruments using Chameleon.

The app has its own custom MIDI mixer, which controls incoming / outgoing MIDI velocity levels rather than traditional audio levels. This allows you to control relative volumes of internal as well as external MIDI instruments. It also allows DigiKeys to be used as a multi-timbral sound source with level mixing, by routing MIDI data on each of the 16 incoming ports to seperate instruments.

DigiKeys features a sophisticated random pattern generator capable of taking advantage of random velocities, probability, note length, sub beats and reverse hits. It can even randomize targetted notes that comply to a chord in the song scale.

The latest update introduces a live matrix performance mode that lets you mix tracks from different patterns in real time, creating scenes to aid your performance.  Patterns and scenes can be triggered remotely from MIDI equipment sending simple note data on MIDI channel 16. Also recently added is the ability to route internal sound to different output busses for adding external effects in AUM. 
 
We also include 3 global effects, reverb, chorus and digital delay which allow per track routing.

• 16 MIDI tracks per pattern.

### 2/5 — Not able to open in Cubasis

*2025-07-19*

Stand alone it’s good but I can’t open it within Cubasis and seen other people having it work???

### 4/5 — Really needs swing settings

*2022-12-07*

I love it, it is immediate and very handy, but no swing makes it really limited. I’d love to be able to get all the instruments really grooving with and inventive swing module.

### 4/5 — Five stars if..

*2022-01-27*

This app had more meter options, like 5/4 or 7/4, or user programmed.

### 5/5 — Does a great job with patterns

*2020-12-11*

With the addition of the midi cc control, it’s now exactly what I was looking for.

**Developer response:** Did you save your work as a song after creating all these patterns? I haven't had anyone else report this problem. Do not rely on a programs saved state as this is not perminent, please always save your work as a song.

### 5/5 — Awesome

*2020-10-14*

One of my best purchases. 4 Pockets does excellent work. Thank you.

### 5/5 — Best sequencer on iOS

*2020-05-18, version 1.10*

This is by far the best sequencer on the iOS platform, allowing multitrack sequencing with lots of high quality built in sounds.

The real beauty of this sequencer is when it is used to sequence external apps, and even better still external hardware, which is done by routing the signals through aum and out via usb, 5pin din, or Bluetooth midi, whichever your preference may be to your hardware synths.

But come on Paul I’m still waiting for you to give me an extra octave or two downwards on the transpose, as when sequencing hardware synths via midi the note received is the note played, at least on analog synths and I need to go lower for bass lines etc.

That having been said I find it impossible to find a better sequencer for features and ease of use on iOS.

### 4/5 — Almost perfect

*2020-03-04*

I love the app. After figuring out how to avoid losing patterns and songs and the few quirks there are with AUM and DigiKeys, I have been building up songs on this. There are a couple quirks and 2 feature requests I would like to mention. I noticed that when saving and loading sessions in AUM, that they DigiKeys settings will remain including patterns and song settings, but even though I saved the “Song” in DigiKeys then saving the session in AUM, when loading, it does not show the song that was saved previously. I have to Load song, then when saving it will show the song name that was saved in the dialog. Plus, not sure if this is a bug in DigiKeys or AUM, but if you switch bluetooth headphones while in DigiKeys / AUM, it will wipe out all the settings in DigiKeys. Here is the 1st feature I would like to see implemented - Import / Export Song to Files/iCloud. This would be great for backup reasons and moving between devices so that the songs that I am working on can be imported / exported. The 2nd feature I would like to see is live recording of steps.

**Developer response:** Thanks for the positive review. I will definately take a look at the bluetooth option as this does looke like some kind of bug. You should always save your song just in case an AUM session fails to restore, although it should save and restore the session just fine. Is there a specific setting that is not saved in the AUM session?

### 3/5 — Good idea but OMG buggy

*2020-03-02*

Works great as a sequencer driving other synths
Crashes every time I try to load a preset of internal sounds
Internal sounds don’t seem to work at all
BUT
Great song form sequencer otherwise, for real
just... can’t... use the internal... soundsssss

**Developer response:** Please try loading in standalone mode to ensure presets have been setup properly prior to loading as AUv3. I think this could be the source of your problem. Please let me know if this doesn't resolve the issue. I will be submitting a new version to ensure this doesn't happen to other users. Once the presets are properly installed the app itself is pretty robust and shouldn't give you issues.

### 5/5 — Brilliant

*2020-02-27, version 1.04*

Loving this app. Will it be possible to scroll the notes at some point as I can’t seem to enter notes in widely different octaves thanks

### 2/5 — Timing issues and missing notes

*2020-02-19, version 1.02*

Feels like this is not ready for prime time as it does not appear to keep good timing. I was attempting to use this to control other synths under AUM, tried Model D, Model 15, Lorentz and had the same issue with all of them - a pattern with repeating notes was not regular and not all notes sounded (different notes sounded on each repeat). Symptoms seemed too much like note-off info being sent late or out of sequence, and on investigation there doesn’t appear to be a way to change/reduce the note length to a fraction of a step for MIDI out data.
