Adjusting volume in pitch-before-duration input?

I’ve searched for this but can’t seem to find what to do. When I use pitch-before-duration, I hold my finger on the midi keyboard (and hear my pitch), and then when I press the number for the rhythm, the pitch plays LOUDLY. Is there a way to adjust the volume of this?

Seems to be a velocity issue? I’m using Noteperformer, if that makes a difference. Thank you for any help.
