ArpBud 2 is a powerful MIDI Arpeggiator app designed for iPhone. It allows users to create unique arpeggio patterns and apply them to their favorite software or hardware synthesizers. Unlike traditional arpeggiators, ArpBud 2 offers unlimited step customization, allowing users to design patterns with complete control over note intervals, velocity, octaves, ratchets, gates, and probabilities.

One of the standout features of ArpBud 2 is its robust randomizer, which enables users to randomize any step for any mode. This adds a dynamic and unpredictable element to the arpeggio patterns, making them truly unique and inspiring.

With ArpBud 2, users can create unlimited patterns within a project, each with different note rates and swing values. The app also supports MIDI CC messages from other apps, allowing for seamless pattern changes during live performances.

ArpBud 2 can be used in standalone mode, IAA (Inter-App Audio) mode, Audiobus mode, and AUv3 Audio Unit plugin mode. It is also compatible with Ableton Live. However, it's important to note that ArpBud 2 is a MIDI effect tool and does not produce sound on its own. It requires both MIDI input and output connections to function properly.

To use ArpBud 2, simply connect a MIDI source, such as a keyboard or MIDI app, to feed the app's sequencer. Then, connect ArpBud 2 to any MIDI-compatible audio app. Finally, arm the sequencer and press play to start generating captivating arpeggio patterns.

ArpBud 2 is an excellent tool for both live performances and arpeggio design. Its intuitive interface and extensive customization options make it a must-have for musicians and producers looking to enhance their MIDI compositions.
