## What is ArpBud 2 AUv3 MIDI Arpeggiator?

ArpBud 2 is a MIDI arpeggiator application that enables users to create distinctive arpeggiation patterns and arpeggiate their preferred software or hardware synthesizers.

Distinct from conventional up/down style arpeggiators, ArpBud 2 offers users the ability to design unique patterns with an unlimited number of steps. Each step can be customized with parameters such as note interval, velocity, octave, ratchet, gate, and probability. Additionally, ArpBud 2 features a robust randomizer that allows users to randomize any step within any mode.

Within a project, users can create an unlimited number of patterns. Each pattern can be assigned distinct note rates and swing values. MIDI CC messages from other applications can be utilized to modify the playing pattern.

From the settings menu, users can assign a MIDI CC number for pattern changes, specify the maximum number of interval numbers, configure randomizer settings, and enable knob control.

ArpBud 2 reacts to pattern changes and step edits in real time during live performances, making it an exceptional live performance tool as well as an arp design tool.

ArpBud 2 can be utilized in standalone mode, IAA (Inter-App Audio) mode, Audiobus mode, AUv3 Audio Unit plugin mode, and supports Ableton Live.

It is important to note that ArpBud 2 is a MIDI effect tool and does not generate sound independently. It requires both MIDI input and output connections to function effectively.

Here’s how to use ArpBud 2:

1. Connect a MIDI source: To ArpBud 2, connect a MIDI source such as a MIDI keyboard, chord sequencer, or any other MIDI application. This source will feed ArpBud 2’s sequencer.
2. Connect ArpBud 2 to an Audio app: Connect ArpBud 2 to any MIDI-compatible Audio application.
3. Arm the sequencer: If using the standalone version or Audiobus/IAA version, press the play button located on the top right corner of ArpBud 2. If using the AUv3 plugin, press the play button on your host application.

## Key features

- Unlimited arpeggiation steps
- Customizable step parameters (interval, velocity, probability)
- Robust randomizer for any step
- Real-time pattern changes
- Supports AUv3, IAA, Audiobus, and Ableton Live
- MIDI CC message control

### 5/5 — Great arpeggiator

*2025-08-09, version 2.7*

I can’t understand the previous review. The arpeggiator is great and super flexible. If you don’t understand how it works in AUM juat watch some tutorial. Super easy.

### 5/5 — Love it but…

*2025-08-05*

I prefer his “kebarp”

### 5/5 — This is definitely my most used arp app

*2025-08-02*

ArpBud 2 is my main arpeggiator. For basic arpeggiation and lets you choose the notes and scales (and octaves), I make great arps out my chord progressions. It’s does justice for trap music

### 1/5 — NOT a Step Sequencer - BEWARE

*2024-01-15*

SooOOoooo one way to view an arpeggio is as a pattern of notes, aka "a sequence". SooOOoooo you'd think if you had 8 steps and you put the first step as 1 (the root), then second as 3, the third step as 5 and the fourth step as 8.....  then played or "fed" this App a note, say a C note. Well you would "THINK" you'd get or generate 1, 3, 5 and 8.

NO, not at all. It doesn't even make sense. WHY? Why tell or indicate to the app what notes, or relative notes to play for a sequence; and then you have to supply the app with more than one note?

**Developer response:** Yes, it’s an arpeggiator. Not a step sequencer, like you said. It needs the chord input from you, and it will arpeggiate it in the note order you designed. What is the problem?

### 1/5 — Buggy

*2023-11-19*

Hi dudes, your app is not working properly on my ipad…newest os and everything updatet. Arpeggios are not as they supposed to be.
Please fix it

### 3/5 — It’s ok

*2023-10-04*

This arpeggiator has potential. The probability, randomization options, and limitless steps are shining points. I’ve been using several instances inside of Loopy Pro, however they have started to crash constantly to the point of uselessness.  Furthermore, as someone mentioned in a previous review, this arpeggiator has no latch which is a basic functionality of any good arpeggiator.

The developer responded to the previous review by saying to activate latch, turn the gate all the way up. I’m afraid that this does not perform a latch function, but rather holds the note through until a note off is received and is aptly named TIE inside the app.

For clarification, latch is a functionality which allows an arpeggiator to temporarily remember the midi note(s) you just played and apply them to the arpeggiator. The difference between latch and a hold function is the hold remembers every note you play until you turn it off like riding the sustain pedal. Latch forgets the previous note(s) each time you play new ones. This is a powerful function as you can, for example, play a chord into the arpeggiator, let go of the keyboard whilst that chord is still arpeggiating, reposition your hands and perhaps change some some your instruments parameters such as filter cutoff-modulation-etc, play a new chord, and hear the arpeggiator smoothly switch to the new tonality. ArpBud 2, unfortunately, does not do this.

### 2/5 — not what I needed

*2023-10-01, version 2.6*

too bad, it is good but it doesn't work like a standard synth arpeggiator that only needs you set BMP for the arpeggio tempo and starts arpeggio everytime keys are pressed. It needs that you click start/play on you host and when you press keys arpeggio will start depending on where beat you are (so not always from start). Not very useful live unless you use click sync and I don't. It will be more useful if you could only set BMP (I use to set it live with tap funcion syncing with real drummer) and play arpeggio always from start when key is pressed.

### 1/5 — It doesn’t work in AUM.

*2022-12-17*

I don’t know what all these fixes were supposed to achieve because it doesn’t work anymore.

**Developer response:** Hello, can you send me an email about the problem you have? The last update fixes the loading of the older presets. Everything should be working fine.

### 1/5 — Not good with BeatMaker 3

*2022-06-06*

When adding as a MIDI effects to a Auv3 synth app like Digital 1, it cuts off the signal instead of playing out the full sound

**Developer response:** Hi, BM3 doesn’t work very well with the AUv3 MIDI plugins unfortunately.

### 3/5 — No latch?

*2022-05-27*

I was starting love this arpeggiator, and then I went to look for the latch function. Is this really one of the only arpeggiators with no latch?

**Developer response:** Hi, you can use the latch function by setting the gate value 100% on a step.
