Scaler 2 piano note velocity Logic Pro

I’m using Scaler 2 in Logic Pro. One thing I can’t figure out is how to change the volume of recorded midi in the piano roll. If I change the velocity of the recorded Scaler midi, nothing happens.
Can anyone help?

Can you see the velocity change? Where is the midi going - does the instrument respond to velocity? Is velocity being filtered somewhere?

Its now fine, don’t know why it was behaving like that
