- Get the free Cakewalk by Bandlab (SONAR Platinum minus some plugins):
https://www.bandlab.com/products/cakewalk- Open your project in CbB.
- Add a Metronome bus if you don't already have one, and and route your audio metronome to it in Preferences.
- Right-click the metronome bus and choose Insert Send > New Aux Track
- Disable Input Echo on the new track, and arm it for recording.
- Enable metronome on record, and record as many bars as you need.
- Or punch record a single bar, Ctrl+L to enable Groove Clip Looping, and roll it out.
Note: If you have a Manual Offset entered under Preferences > Audio > Sync and Caching > Record Latency Adjustment, you'll want to zero it temporarily to get sample-accurate click timing recorded.
