Create Unique Arps

Features & Capabilities

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:

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.
Connect ArpBud 2 to an Audio app: Connect ArpBud 2 to any MIDI-compatible Audio application.
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.

User Reviews

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.)

Recent reviews

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

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?

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.
