Piano Roll tuning

I have music track I want to write vocals for however the music is in-between the keys pitch. so a semi tone off pitch from every key on the piano roll, is there a way to detune the piano roll? if not this would be a good feature . Any suggestions how to deal with this ?

If you have the Pro edition you can detune notes by dragging them while holding ctrl+shift.

Otherwise just draw the correct pitch manually with the pencil tool.

That’s a good work around thank you , however it would be less work and not be a work around if you can adjust the pitch’s of the piano roll
