DigiKeys AUv3 Sequencer Plugin1.15 - App Store

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.

Fixed an issue with the popup menu that wasn't refreshing properly all of the time.
Updated for compatability with future versions of iOS. 1.15 09/03/2025 Fixed a mapping issue with the male choir preset. 
(Please run in standalone mode, click the cog button at the bottom of the screen and select remote presets and then install presets to ensure they are overwritten).
DigiKeys now releases audio when not planying and a background task.
Other minor fixes. 1.14 02/15/2022 You can now select patterns using MIDI CC 20 (values 0-24).
Other minor fixes. 1.13 12/04/2020 Fixed an issue which caused a possible crash when attempting to add controllers to tracks 13-16.
Other minor changes. 1.12 11/11/2020 Finally you can load DigiKeys as a pure MIDI processor in AUM/Cubasis etc. (without internal audio).
Fixed the excessive flutter issue on the delay.
Other minor fixes. 1.11 10/14/2020 Added a vertical modifier for notes of type 'octave' to allow notes outside of the grid range.
Increased the allowable number of samples per multi-sample to 32 for future Chameleon compatability.
Added a few more default instrument presets. 1.10 05/18/2020 Fixed an issue which caused pitch bend to not re-center if using as a multi-timbral sound source with MIDI-In turned on.
Fixed a corrupt graphic which caused a couple of the graphic eq buttons not to show correctly.
Other mindor fixes. 1.09 04/29/2020 Fixed an issue with the portamento resetting.
Other minor bug fixes. 1.08 04/23/2020 Fxed an issue which caused occasional artifacts in the delay effect when using 'flutter'.
Fixed a few minor issues related to stability. 1.07 03/14/2020 This version prompts the user to run in standalone mode prior to allowing it to run as an AUv3. 

This is required to ensure the presets are installed correctly and permissions are granted. This is only required on first install but required to avoid issues accessing the internal presets. 1.06 03/04/2020 Now allows patterns up to 64 beats in length.
A few minor interface bug fixes. 1.05 03/02/2020 Fixed a copy/paste track issue which meant pasted data did not have the correct output MIDI channel. Paste pattern was uneffected.
Added an extra 2 busses on output giving a total of 6.
Added an experimental swing option to the Metronome dialog (double tap).
Other minor bug fixes and improvements. 1.04 02/23/2020 Fixed an issue which caused a crash when pressing the 'All Notes' button on a chromatic scale.
Fixed some MIDI timing issues.
Other minor bug fixes. 1.03 02/20/2020 Fixed an issue with long sustained notes being cut-off.
Added multi-bus audio output support for use in AUM.
Added the ability to remotely trigger patterns and scenes using MIDI.
Added a Live Matrix mode that allows live performance and scene creation. (iPad Only)
Other bug fixes. 1.02 02/19/2020 Added an option to remove all but the neccesary samples if using as a MIDI controller only.
Added an experimental track loop feature (see help for details).
Fixed a copy/paste pattern issue where the pattern length was not set correctly in the pasted pattern.
Fixed an issue which prevented you from swiping up to full velocity when adding notes to the top row of construction grid.
When pasting patterns you now get the choice of pasting at the start of a pattern or into the current page.
Other small bug fixes. 1.01 02/13/2020 1.0 02/11/2020
