You Can Change The Entire Setup (Patch) Of The U-20 By
Sending A Program change On The Control Channel. This
Will Change All Timbres And The Rhythm Set As Well As
The Effects Settings. (Program Changes On The MIDI
Channels Used For The Individuals Parts Will Change
Only The Timbres For The Selected Part)
It Is A Good Idea To Set The Control Channel To A MIDI
Channel That Is Not Being Used By The Individual Parts
In The Performance. Send A Program Change On The
Selected Control Channel From Your Sequencer

To Turn Active Sensing OFF*
Press
Press 5 Times & Select Tx Active Sensing
Press And Set Tx Active Sensing OFF

EDIT Setup MIDI Kybd TX Active Sensing
By Default, The U-20 Has Active Sensing Turned On. This
Sends A MIDI Pulse Over The MIDI Wire Every 300ms. I Prefer
To Turn Active Sensing Off Because MIDI Message LED's On The
Rest Of My Devices Start Going Bat-Shit Crazy Like A Strobe
Light. Very Distracting. I Like To See MIDI Message LED's
Trigger Only When I Play The Keyboard Or When The Sequencer
Is In Playback-Mode. It Also Unnecessarily Fills Up The MIDI
Buffer Making Troubleshooting Difficult. Also, Several
Devices In A MIDI Chain With Active Sensing Turned On Can
Cause MIDI Buffer Overflows
