## What is PatternBud?

PatternBud is a MIDI CC and Program Change sequencer designed for controlling patterns across your music applications. Create sophisticated song arrangements by sequencing pattern changes in your synthesizers, drum machines, and sequencers based on musical timing such as bars, beats, or note values.

Key Features:
- Multi-track sequencer with unlimited tracks and steps per track
- Individual MIDI channel and CC number assignment per track
- MIDI CC and Program Change message support for each step
- Flexible step durations: bars, beats, note values, seconds, or minutes
- Advanced action system for dynamic pattern control
- Random value generation with customizable min/max ranges
- Step-based actions including pattern jumps and random pattern selection
- Copy, paste, insert, and delete operations for efficient workflow
- Real-time step progress visualization with duration indicators
- Tempo synchronization with host applications
- Pattern switching via MIDI CC input
- Comprehensive MIDI input and output routing
- AudioKit-powered MIDI engine for precise timing
- AUv3 plugin format for seamless DAW integration
- Standalone app operation for hardware setups
- iCloud based preset manager

Advanced Action System:
- Jump to specific steps or patterns
- Trigger random steps within tracks
- Send custom MIDI notes, CC, or PC messages
- Execute actions at step start or end points
- Chain multiple actions per step

Perfect for controlling:
- Pattern-based synthesizers and drum machines
- Sequencer applications with multiple patterns
- Hardware devices via MIDI CC/PC messages
- Complex song arrangements and live performances
- Any audio app supporting MIDI CC or AU parameter control

PatternBud serves as the conductor for your electronic music setup, enabling you to create evolving compositions by orchestrating
pattern changes across your entire rig. The application produces no audio itself - it focuses purely on MIDI control and timing.

For AUv3 plugin usage, you'll need a compatible host application such as AUM, Cubase, apeMatrix, BeatMaker, or similar DAW
software.

### 5/5 — Does exactly what I need

*2025-09-27*

I’ve been looking a long time for a simple MIDI sequencer that runs as a plug-in within main stage. I finally found it. The plug-in will execute PC or CC messages at one or more bars within the song and allows me to access any of the controls I have set up within mainstage. In my case, I use it to change guitar effects, vocal, harmonies, etc. I can add it to each of my patches/songs in main stage, customizing it for each song. Fantastic!

### 5/5 — Key for song-building in AUM

*2025-08-03*

Let’s me change pattern across multiple sequencers easily in AUM. It’s essential for my live workflow.

### 3/5 — Great but also annoying

*2025-06-04*

It’s a great sequencer but not without its flaws. 
If I have two or more tracks that are each triggering notes (in this case samples to outboard Roland P6 sampler) at the very first start bar then only one sample will play not two, until the next block then they all play. Hard to explain but that’s why I stopped using PatternBud and moved to Helium.

### 3/5 — Good concept, but need automation to chance cc value in step

*2025-01-04*

This tool would have been amazing if it would allow cc scaling from value a too b within a step

### 4/5 — It works well but improvements could be done

*2023-12-16*

I use it with PatternBud+BrainBud. It is able to change the key. However, this only subject to the on screen keyboard of ScaleBud, but not my own midi keyboard (actually it is a 4x4 Drum pad, mapping with note 1/3/5/7 of different octave making sound like a chord)

For example, when I am hitting a C3 note in every beat, the BrainBud changes from C Major scale to G major scale. As a result, my notes C3 is still keeping as C3, but not transposed to G3 which is i expected to be. That means the C3 is not mapped to the First note of the scale and so on (while the notes of the on screen button keep switching as it should be)

I hope this can be achieved as this help as it help generating pattern with any controller with non piano keyboard layout

### 3/5 — Functional but a bit cumbersome

*2023-11-03*

First off, this app is constantly crashing. I contacted the developer but haven’t heard back. 

That said, this is a focused and very useful little tool. I have not found anything like it. 

Unfortunately it is a little cumbersome to program. Would love to see reorder by drag and drop, drag to delete, copy/paste or duplicate track, etc.

### 5/5 — This is very good

*2023-02-17*

I Need This App To Send cc Message to a Pedal with a konstant value. And Trackbased length ( 1 bar Or 4 Bars etc).It‘s Perfect!!

### 1/5 — Horrible interface

*2022-10-25*

The per step editing take way to long and ist very uncomfortable. Not worth the money

### 1/5 — Don’t WORK in AUM

*2022-10-08*

Don’t open in AUM
