Hi there, i seem to be only able to control ctrl message with this and not velocity. What could i be doing wrong? I can get an incoming audio signal to control for example modulation wheel on CC1 but not velocity, can anyone help? I'd like to have a piezomic control velocity on a vst and have a non velocity sensitive midipiano do the notes so i need to have the vst midi channel receive input from two sources at the same time.. thanx for any help
