Question: Note-off value always 0 on send?

Hi,

I am routing the input of my Roland A49 midi keyboard to an ipad using renoise. I created a midi out device with output “network session”. I can see in the midi monitor that also a note-off value changes in the input data. But the note-off-value is always 0 in the output data. Why this? Does Renoise set it to 0?

btw. can I route the note-off value to e.g. the release value of a vsti?
