Follow these steps to change the default MIDI CC input on the Organelle:

1. Eject the USB drive in your Organelle and place it in a USB port on your computer.
2. Download [PureData](https://puredata.info/downloads) on your computer if you have not already.
3. Download [mother.pd](https://canada1.discourse-cdn.com/flex035/uploads/critterandguitari/original/1X/03ffe4aa85bf33ac86425a44babee49ab105319f.pd). A version of this file is always running on the Organelle and interfaces with every patch. To set your Organelle to receive MIDI CC controls of your choosing, a new mother patch must be created to override the built-in mother.pd.
4. Move mother.pd into the patches folder on the Organelle drive:

5. Open mother.pd in PureData.
6. Click the MIDI sub patch labeled [pd MIDI]:

7. Find the groups of objects in the top row that start with [ctlin 21 1], [ctlin 22 1], [ctlin 23 1], and [ctlin 24 1]:

8. Edit the [ctlin 21 1] object to reflect your desired MIDI CC for Knob 1 on the Organelle. For example, if your MIDI CC of choice is 7, and your MIDI channel of choice is 4, change [ctlin 21 1] to [ctlin 7 4]:

9. Save and close the patch.
10. Eject the Organelle USB drive and test on the Organelle.
