SteveCherelle Thanks, the screenshot helped. So you are using your pedal in mode C which means that it sends CC messages. Please start your Blueboard in mode B by holding down the B button when starting. That will make the board send Note On / Off messages. You only need to select mode B once, the pedal will remember this setting.
Once you switched to mode B, relearn your commands and all will work just fine.
ST does and did always interpret CC commands differently to Note On / Off. For Note commands ST does only react to Note ON. For CC commands it reacts to state changes. The pedal is sending state 127 wenn pressing the button and 0 when releasing it. These are 2 seperate triggers for ST.
I guess you accidently switched to mode C and therefore experience these problems now.
