Yes it's fine it's all from breathcontrol. Only odd thing is it's sending it's breathcontroler data as expression data too, which is handy if you need it. I use a simple yamaha breathcontroler and a yamaha windcontroler so I have no idea if you can maybe change it's behaviour to only sending breath or expression. It probably also sends some lip/embouchure data, which is pitchbend on my yamaha.
