## ScaleBud Description
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.

ScaleBud 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.

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.

Standalone app requires iOS 10.0+
AUv3 plugin requires iOS 11.0+ and a supporting host app.

ScaleBud also offers its core components open sourced on GitHub. Feel free to fork them, send a pull request to make it better, open an issue to share your ideas or give them a star if you like them.

## ScaleBud Reviews in United States

### ***** "Favorite Controller"
This is my favorite way to play keys. I use it with Ableton and Studio One on Mac. As others have mentioned, this doesn’t play well with BM3 as a midi effect. This has to do with how midi is implemented in BM3, not this app. You can find the same issue on desktop when looking at Maschine. Ironically enough, BM3 at it’s core, is Maschine for iPad. And the way you have to implement midi for pads that can also be played chromatically will always cause a software to not play well with MIDI FX. There are a couple work arounds.. but suffice to say, this is not the developers fault.

Love the app. Peace

### *---- "Does not work as advertised"
This app does not work with BeatMaker 3. There is little to no instructions on how to use or trouble shoot problems with the app. Simply put, this is a total waist of money.
-- throwawaynickname009977, 2021-02-05

### ****- "Very good but one major flaw"
I really like this app and I'd give it five stars if it had a way of making the text black. Right now the text VERY light grey on a white background. It's almost completely illegible
-- app3aday2, 2020-05-02

### ****- "Crashes with GarageBand."
Everytime I try to use it with GarageBand it crashes. Not sure if it’s on GarageBand’s end or not. Other than that this is a killer app
-- Floating Door, 2019-11-26

### ***** "Good app"
Great app for learning how to play chords. Developer is very nice and cares about the app.
-- Oioi u, 2019-06-10

### ***** "Indispensable tool"
Scalebud is a must-have midi controller. I love the chord types offered (as another review suggested I also would like to see more chords added including sus2 and sus4).
The fact that also works as an audio unit means I can use multiple instances to play keys and chords at the same time. 
Thanks to the developer for making this wonderful app.
-- Leesa101, 2019-03-02

### ***** "Finally, I can play complex chords and without logic!"
You should put out more videos on this amazing controller, as there’s nothing to see other than the app page! But it now allows me to learn and play complex 11ths and more! Hopefully in future updates, you’ll add sus2, sus4, add2, augmented, diminished, and 6/9 chords as well, it’s very well a recommended addition. As for now, it’ll go very nicely for ambiance and could possibly be arpeggiated. Everyone, if you wish to have easy access to a chord dictionary that works well with your synths, try this!
