Step 10: Audacity... Again
- Open Audacity and creat a new project.
- Drag in the Green, Red, Yellow, Blue and Orange audio files you made in the previous step.
- Export the audio and name it Strum.
- You will get a warning that the track will be mixed down to a single mono channel. This is exactly what we want for this, because it creates an audio track for the strum button.
