## Description

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.

## Review summary

ArpBud 2 AUv3 MIDI Arpeggiator is praised for its intuitive interface and solid compatibility with other synths, plus flexible note/scale/octave control and advanced options like Ratchets and probabilistic variation. However, multiple reviews flag reliability and host-compatibility issues, including no latch support, crashes or instability across DAWs, notes or parameter changes not applying, and occasional non-functioning behavior in some apps. Overall, it offers a strong feature set but reliability bugs hamper use in real-world setups.

### Pros

- Intuitive to use
- Works well with other synths
- Flexible arpeggiation control (notes, scales, octaves)
- Advanced features like Ratchets and probability/randomization
- Active development with frequent updates

### Cons

- No latch functionality (latch missing)
- Stability and compatibility issues across DAWs/AUv3 hosts (crashes, signal cuts, silent notes)
- Notes/parameter changes sometimes have no effect
- Some hosts (e.g., BeatMaker 3) report non-functioning or buggy behavior
- Occasional bugs requiring updates (crashes, freezes, etc.)
