I have a used 2001 “Mackie Logic Control” running in “Mackie Control mode” connected into ardour’s “mackie control in” and “mackie control out”. The main physical “RECORD” button correctly turns on and turns off Ardour’s main Record enable button. However, the LED on the mackie doesn’t remain on when pressing the physical button. The LED is only lit during the time I depress the physical button. It should really remain on after I lift my finger of the button.
I should note that the button works correctly when only using Ardour’s gui button. Pressing the gui button once will turn the led of the physical button on. And pressing the gui button a second time will correctly turn the led of the physical button off.
