ArpBud 2 is a MIDI Arpeggiator app where you can create unique arp patterns and be able to arpeggiate your favorite software or hardware synthesizers.

Unlike the traditional up/down style arpeggiators, you can design your unique patterns with unlimited number of steps. For each step, you can set the note interval, velocity, octave, ratchet, gate, and probability. ArpBud 2 also has a very powerful randomizer where you can randomize any step for any mode.

In a project, you can create unlimited number of patterns. For each pattern, you can assign different note rates and swing values. You can use MIDI CC messages from other apps for changing the playing pattern.

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

ArpBud 2 would react your pattern changes and step edits on the fly when you are playing it live, which makes it a great live performance tool as well as a arp design tool.

You can use it on standalone mode, IAA (Inter-App Audio) mode, Audiobus mode, AUv3 Audio Unit plugin mode. It also supports Ableton Live as well.

ArpBud 2 is a MIDI effect tool and does not produce sound on its own. It needs both MIDI input and output connections in order to work.

- Connect a MIDI source to ArpBud 2, like a MIDI keyboard, chord sequencer, or any other MIDI app to feed ArpBud 2's sequencer.
- Connect ArpBud 2 to any MIDI compatible Audio app.
- Arm the ArpBud 2's sequencer. If you are using the standalone version or Audiobus/IAA version then you can press the play button on the top right. If you are using the AUv3 plugin, then you can press the play button on your host app.

Fantastic Developer!

These apps are great, and they are being upgraded almost daily. Can’t beat that. Not sure why one person gave them a 1 Star, but I’d being willing to bet it was error on their part not the app.

Arpbud not working, can’t input.

Just purchased the bud bundle and Arpbud doesn’t work at all. This is so disappointing. You can’t change any value on the note tab, and all of the other tabs only changes a single random lane regardless of which one you drag on. That is the standalone, as a auv3, simply nothing works at all. Please fix this, is this app even a year old? So disappointing to drop $20 on an app and a big chunk of what I wanted the app for doesn’t work as advertised, or in this case at all. And it’s not an error on my part tried reinstalling, restarting, and did tutorial twice.

Developer Response ,

That’s a very strange case. The app works fine actually. I’m not sure how’s that possible. Can you try the app with a different iPhone or iPad? It might be an iOS problem.

Simple, powerful and works best with AUM

This is amazing! Very intuitive to use and works so so well with the other synths. Plus the addition of Ratchets along with other variables is great! Exactly what I was looking for!
