Well I'll be .... Thanks for the tip ! :)
Turned off Airturn and set the BlueTurn to mode 3 (Left/right arrow) and now I can browse through playlists ! :)
According to IK Multimedia their BlueTurn pedal is compatible with iReal Pro ?

I've tried all three modes without any luck so far ...
And iReal only mentions AirTurn pedals in the menus ...
Am I fighting a losing battle or...
