Find the right music app for your setup

AUv3 MIDI sequencers, arpeggiators, chord tools, synthesizers and audio effects. Each app runs standalone or as a plug-in in your host, and each one does one job well.

Generate patterns and sequences

MIDI Sequencers and Generators

Step, generative, polyrhythmic, physics and text based MIDI sequencers. Load them as AUv3 MIDI plug-ins in hosts such as AUM, Loopy Pro, Logic Pro for iPad and Cubasis, and send their notes to any synth. Some of them have a built-in sound, so you can also use them standalone.

Turn chords into arpeggios

MIDI Arpeggiators

Hold a chord and let the arpeggiator play it as a rhythmic pattern. Edit the steps, the rhythm and the octaves, and sync to the host tempo.

Play chords and stay in key

Chords, Scales and MIDI Keyboards

Chord progression sequencers, chord pads and scale keyboards. Write a progression, play chords with one finger, or play only the notes of a scale. Good for players who do not know theory, and for players who want to go faster.

Record, fix and control MIDI

MIDI Utilities

Small tools for the MIDI chain: record and loop MIDI, quantize notes to a scale, and control the other Bud apps.

Make sound

Synthesizers, Samplers and Instruments

Synthesizers, samplers and drum instruments. Wavetable and supersaw synths, an ambient touch synth, a techno bass line generator, a breakbeat synth, a speech sampler and a video chop sampler.

Process audio live

Audio Effects

Performance effects for your mix or your whole rig: glitch, rolls and trance gates, vinyl scratching, rotary movement and morphing effects. Put them on a track or a bus in your host and play them in real time.

Questions

What is AUv3?

AUv3 (Audio Unit version 3) is the plug-in format of iOS, iPadOS and macOS. An AUv3 app loads inside a host app, such as AUM, Loopy Pro, Logic Pro or Cubasis, like a plug-in in a desktop DAW.

Which host apps can I use?

Any AUv3 host. Popular hosts are AUM, Loopy Pro, Drambo, Cubasis, Logic Pro for iPad and Logic Pro for Mac. GarageBand loads AUv3 instruments and audio effects, but not MIDI effects.

Do the apps run on a Mac?

Apps marked Apple Silicon run on Macs with Apple silicon (M1 or later), standalone and as plug-ins in Logic Pro and other AUv3 hosts.

Do I need a host app?

No. Each app also runs standalone. Some MIDI apps have a built-in sound, and all MIDI apps can send MIDI to other apps and to external hardware.
