ScaleBud is a music theory tool for composers, artists and learners. It has more than 40 most popular scales and counting. AUv3 Plugin, Audiobus MIDI Sending/ Filtering and Standalone app included. It has a very simple, single-view interface that you can choose the scale and key you want to work as well as note or chord mode selector on the left side. Right side lists the scale notes or chords you want to work with. In note mode, you can fastly jump between notes in the scale by selecting them from the list.

In chord mode, you can see the triad, 7th, 9th, 11th or 13th chords for each note in the scale. You can jump between them quickly as well, by pressing the chord you want to play from keyboard. Also, in chord mode, you can set the octave you want to play for the chords from left side of the keyboard.

It comes with an AUv3 MIDI plugin and standalone versions. You can directly control your iOS, Mac or PC audio apps with CoreMIDI. Just open the settings menu and select the MIDI Out you want to send MIDI to.

ScaleBud also supports Audiobus MIDI Sending and Filtering. You can send MIDI from Audiobus 3 app just like regular CoreMIDI workflow. Also, in Audiobus MIDI Filter mode, you can feed MIDI Input data from your hardware or MIDI app, and ScaleBud filters out the off-scale notes in note mode, or plays the corresponding chord, if any available, for each note, like a chorder, in chord mode.

AUv3, AudioBus 3 Support & More

You can use ScaleBud with Audio Unit version 3 hosts like Audiobus 3, AUM, Cubasis 2, Beat Maker 3, apeMatrix and Sequencism. As an audio unit plugin, it both maps/filters your MIDI Input to the MIDI Output you route, and sends the notes/chords you pressed from its keyboard. In chord mode, you can press any type of chord from the list in order to make chorder generate chords in that type. For example if you press a 7th chord, it will generate 7th chords for each note you send it from your MIDI keyboard.

Also, it has several presets but you can save your custom presets with the supported hosts. So, you can quickly jump between keys, scales and chords you want to work with.ScaleBud is not an audio app. It just creates or filters MIDI data coming from input and sends them to MIDI output. It does not generate any sound in any mode.You can always send feedback for bug reports, feature requests or rate the app from the Support section in Settings menu.

ScaleBud is available now for iOS (iPhone/iPad) for $4.99 USD on the Apple App Store.
