No, you connect the airturn to your device that runs ST3 and (if thats possible) set one of the buttons to send that specific CC that your mixer identifies as tap tempo for your delay.
in the lyrics editor you just tap that button 4-6 times (should be enough) and every song the tap tempo
on your mixer should be set to that tempo youve tapped.
i do that with my Helix, but when i load a new song i dont bother connecting the Helix, i used a similar pedal (iRig BlueBoard- that one can be set to whatever you want) and just tap a few times and thats that.
if your BT pedal cannot be set, you can just tap the tempo and then manually change the values as needed afterwards.
ST3 has a really great midi learn feature, and you could actually find out the actual value you're looking for by connecting your mixer to ST3 and pressing the midi learn on any function ST3 offers and then hit the tap button on your mixer (on the software app for it), ST3 should capture and reveal the value you're looking for. I did this to find out the mute for one on the channels on my QU-SB.
let us know if it worked 🙂
