The PAD LINK function of the OCTAPAD SPD-20PRO is used to play the instrument assigned to a different pad when you strike a certain pad.
Up to four sounds can be configured to play at the same time when you strike a pad.
If you want to play the Inst Main and Inst Sub together that are assigned to two pads, set the Layer Type to “MIX.”
NOTE: OCTAPAD SPD-20PRO is not available in all regions. Please check with your local distributor for more information. https://www.roland.com/global/international/
