The XP80 has a realtime erase function for erasing unwanted data during mix recording of a drum loop. Use the following procedure to enable realtime erase:

1. Enter the RECORD mode [so your drum pattern is looping].

2. Press F5 [Erase].

3. Hold down the key that you would like to erase.

NOTE: Any recorded events of that note will be erased for as long as you hold down the key.
- If you hold down two keys, those notes [and all the notes in between] will be erased.
- If you hold down the REC button, all note data will be erased for as long as you hold the REC button.

4. Press EXIT to leave the erase mode.
