Hello, 
I have an integration problem with Studio One, the transport functions usable with the "Track-instance" key are not active. 
- I have Studio One Artist 5.5.1 
- Komplete Kontrol A61
- I have the latest firmware
- Under Windows 10 
- I tried to restart the computer and unplug the keyboard
- The midi controls in the plugins work
Here is my configuration in Studio One :
    
        
             
    
    
        
             
    
    
        
             
    
    
        
             
    
    
        
             
    
    
        
             
    
Thanks for your help
