Occasionally, it's desirable to completely erase a single track, without erasing the whole Phrase memory.
Here are the necessary steps to do this:
1. Record phrases on Track 1 and then 2.
2. Press the right pedal twice to stop playback.
3. Press the Track Select button of the Track you wish to clear.
4. Hold the Right pedal, then press the Left pedal.
This process requires the RC-30 to be stopped. There is no other way to achieve clearing one Track completely after performing the initial recording, or overdub.
If you need to ability to clear on the fly during live performance, you would need the RC-300.
