Hi @Santi_Gil, for the Drum Swap buttons on the GRV6, I would probably map these to the Kicks/Drums (Track 1: Trigger Sample 1) of the Looper. Then Duplicate the mapping (by sliding left on the command you just mapped) and mapping the same button to Neural Mix Mute (3ch: Drums). This will basically swap the existing track drums for drums from the Looper.
Here’s a short video of how this could function: GRV6-Drum Swap.mov - Google Drive
