ArpBud 2 AUv3 MIDI Arpeggiator by Cem Olcay

Cem Olcay released ArpBud 2 AUv3 MIDI Arpeggiator. This follow up to the original 2018 app incorporates greater MIDI control, allowing for you to change your arpeggiations on the fly. AUv3 is also a big upgrade!

ArpBud 2 AUv3 MIDI Arpeggiator

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.

There are some short demos on the official YouTube channel. Gavinski's Tutorials did a 32 minute tutorial if you want to dive in, and SoundForMore takes us into the deep end with a new tutorial series for ArpBud 2.

can this do (for example) 8 steps on notes, but different amount of steps on velocity , octave etc etc?
or are they all using the same step length ?

You could probably use a midi tool to combine the notes from one instance and the velocity from another.

Yes in ArpBud every step is of same length (time), but you can change velocity, octave, gate, ratcheting, random parameter (you can choose which one you want to randomize) and probability to play for each one. It's up to you how many steps you want (unlimited). If you want to have variable step length for each step, look at Stepbud.
What I love about Cem's apps is visual simplicity combined with total programming versatility. For example, to create nonlinear drum groove Stepbud is my first choice (despite its not intended to do it by design).

I meant.

8 steps for note
6 steps for velocity
7 steps for probability .

Or maybe different tempo speeds on each..so velocity runs at half speed.. that type of off kilter modulation

It looks like all have same step amount.I’ll keep an eye on more vids as they appear

@Re5etuk : no, the number of steps are the same for all options. But I agree that this would be a great feature to have!

Oh, gotcha. Well, StepBud and this ArpBud 2 are based upon concept of recording all these parameter's changes once per step. So you in any way will have vertical synchronization with every new loop start. If that isn't what you want, you can use several instances of the app inside the AUv3 host of your choice, and program every other app instance with different length, but when you will point all these instances to your synth you will need something like Mozaic to filter out all MIDI messages except desired type out of every other instance.
Otherwise, maybe Thesys from Sugar Bytes will serve you better? (not sure though :)

I can see how this would work for notes and cc messages, but I am not sure how it would work for pitch and velocity as I think those are both linked to the note on message. This is of course and interesting approach, but I for one wouldn't know how to make a script that filters pitch on one stream and velocity on another and then merges the streams so there is not conflicting note on messages. Ideas?
