BrainBud controls the keys and scales of the Bud apps all at once. Connect BrainBud’s MIDI out to MIDI inputs of:

- SnakeBud
- PolyBud
- MelodyBud
- ShiftBud
- ScaleBud 2
- In Theory
- Textquencer
- Binarhythmic
- Auto Bass
- BounceBud
- MuseBud
- Kebarp
- FuncBud
- Note to Be


You can also broadcast the current key/scale to the newly connected apps with Budcast button.
If you’d like to experiment, you can try the randomise button.

With the AUv3 plugin, you can change the BrainBud's parameters or even automate them with AU parameters.
For using the AUv3 plugin make sure you have an AUv3 host app such as AUM, Cubasis, Nanostudio, apeMatrix.

BrainBud is a MIDI based app and requires other Bud apps present in order to work right. If you don't have any other Bud apps mentioned above, you can't make a use of BrainBud. 

BrainBud doesn't produce any kind of sound on its own.
