no man, this is donne via plug in automation (not via controlers on the midi key editor drop down list).. ex: just choose a nice filter plug in as an insert 4 yer audio track (or vst i) ... then the proced~e as the top explanation (w for recording automation, R for reading the recorded automation)... another way is 2 use the eq as a low pass (choose de highs eq, change the Q setting until u get a cut filter) or an high pass (low eq).. but cubase mkixer's eq. sound a bit digital! :(
