A really useful feature on the COBALT8M is to use the quick recall buttons to have fast access to patches that you use often or rapidly changing patches during a recording or live performance.
To use this feature, hold the patch button to the right of the screen and press one of the buttons to the left of the screen.
The 8 buttons from Velo to Chord will have a patch associated with them.
To change the patch that is stored in that location. Navigate to the patch and hold patch and the button you want at the same time. The screen will show that patch is stored to the slot.
There's a Modal Minute guide here for further information.
