It seems like section 2 (The sections numbered 1 to 8) has an overlap between grooves and single hits. If “Pattern” button is active GA4 will show grooves and they can be played by clicking the Pad, hitting the keyboard in GA4 or by playing a MIDI keyboard. When the “Instrument” button is active, section 2 (yes the same section) will show single hits Pads available through clicking. However the groove will still play on GA4 keyboard and the MIDI keyboard. I also drew notes in the piano roll and for section 2 they only played grooves. What is the purpose of this overlap?
How do I load a drum set without any grooves? I can get to load a set with all Pads grey, however there will still be grooves when the MIDI keyboard is played or the keyboard in GA4. I am not able to load any set without clicking on a groove name, no matter from which menu, a groove list always emerges.
