How can I map my Tascam dm 4800 in cubase 13

Please can someone help me to midi map control my Tascam DM 4800 in cubase 12

Hi and welcome to the forum,

In the Studio > Studio Setup click the + button to Add Remote Device. Choose Mackie Control and set the MIDI Ports. To get 16 channels, add one more Mackie Control.

Be aware, the Mackie Control at the bottom is controlling channels 1-8, therefore you have to select Port 1. The most to Mackie Device is the most right at the table (in case of 16 channels, it controls channels 9-16). Therefore select Port 2.
