DigiKeys is an AUv3 MIDI sequencer plugin designed for use with AUM and other AUv3 compatible host applications. This powerful tool is great for musicians who want to create and control music patterns easily. With DigiKeys, you can work with either external MIDI-based synth engines or its internal synth engine, which features over 100 custom presets.

The DigiKeys app functions as a 16 channel multi-timbral sound source, allowing you to send MIDI data to 16 different internal instruments. This flexibility lets you explore pattern-based song construction effortlessly, making it easy to build and expand on your musical ideas.

Creating music in DigiKeys is simple. You can make looped patterns with up to 16 tracks per pattern. Each track can be 32 steps in length and has options for its own playback speed, transposition, and effects routing. You can also chain patterns into songs, linking up to 256 patterns together. When you want to change the mood of your song, you can use the transpose function for chord changes without needing to redesign your patterns.

DigiKeys is especially useful for driving other MIDI compatible AUv3 plugins while also offering its own internal synth engine. If you have the 4Pockets Chameleon sampler plugin, DigiKeys will automatically grant you access to those instrument sounds, making it easy to broaden your sound library.

One important feature is the custom MIDI mixer. This mixer controls incoming and outgoing MIDI velocity levels instead of traditional audio levels, which allows for better volume management between internal and external MIDI instruments. This means DigiKeys can work as a multi-timbral sound source, routing MIDI data on each of its 16 channels to different instruments seamlessly.

The app also features a sophisticated random pattern generator. This generator can handle random velocities, note lengths, and more, giving you new musical ideas. It can even randomize targeted notes that fit within the song scale, adding even more creativity to your patterns.

The latest update introduces a live matrix performance mode, which allows you to mix tracks in real time. You can create scenes that help enhance your performance. Patterns and scenes can be triggered remotely using MIDI equipment, making it easy to switch patterns when performing. DigiKeys also supports multi-bus output in AUM, so you can add external effects as needed.

Additionally, DigiKeys includes essential global effects such as reverb, chorus, and delay. You can route these effects per track to enhance your sound further. The app features editable patterns and a reverse mode feature, allowing for creative variations in your music. You also have the option to control track mutes and solo options, and a 6 band EQ is available for fine-tuning your sound.

For those who prefer more control, DigiKeys allows real-time and step pattern recording. It also includes remote MIDI sync capability and a comprehensive clipboard functionality for easy copying and pasting of patterns. You can back up your work using the HTTP interface, ensuring your songs are safe and easily retrievable.

With its many features, DigiKeys empowers musicians to explore a range of creative possibilities with ease, making it an essential tool for anyone looking to compose music in a fun and flexible way.
