registered Parameter Number (NRPN) messages transmitted. 

Additional Continuous Controllers 

(CCs) Transmitted/Received 

 

The following table details how CCs are mapped onto Tetra’s controls. They are 
transmitted when MIDI Parameter Send is set to CC in Global, and recognized 
when received when MIDI Parameter Receive is set to either CC or All in 
Global.
