What's New

Fixes a crash happening in AUv3 mode when a snapshot is long-pressed.
Snapshot CC numbers start with #1 instead of #0.

App Description

RhythmBud is a MIDI effect application that would transform incoming MIDI messages into the rhythmic pattern you will create on its editor. Supports AUv3 Audio Unit plugin, Audiobus, Inter-App Audio (IAA), Ableton Link and Core MIDI (Standalone).

It sits between a MIDI sender (external hardware or any MIDI controller/sequencer app) and a MIDI receiver (any audio app or external hardware). As long as you connect its MIDI input and output you are good to go.

It has a pretty easy-to-use timeline editor, where you can create rhythm patterns. You may add different effects for your every pattern by tapping them on the timeline, such as strumming effects, arpeggios, transposition, velocity manipulation, ratchets and so on.

When you are ready, press the play button and start the RhythmBud engine. As long as it receives MIDI notes, it will generate your rhythm pattern and send it to your assigned MIDI output port. Even if you change the playing note/chord, it will adapt instantly!

It has a neat feature called “Snapshots” where you can save the current RhythmBud configuration instantly and come back later. You may also control your snapshots via MIDI CC messages or Audio Unit Parameters. You can create a whole song with that feature in your project. It also supports “User Presets” in AUv3 mode.

Another great feature is the “Record Mode” where you can record a pattern by tapping the toolbar—like clapping your hands or snapping your fingers for creating a rhythm pattern! Press the “Done” button when you are done.

If you are not happy, you can always undo/redo your actions as well. You can also quantize your pattern on different timing levels. If you want to clear everything and start over again, just press the clear button.

RhythmBud is using the open-source AudioKit framework under the hood. Also, it offers some other open-source frameworks as well. Check them out on GitHub!

*** Disclaimer: This is not an audio app! It does not generate audio. This is a MIDI effect app that needs both MIDI input and MIDI output routing. It does not transform the MIDI until you creating a pattern and pressing the play button.
