It seems that I can't get a good legato passage with the vibrato instruments, especially the flute. I'm using the sustain pedal, and even slightly overlapping notes in order to get a smooth phrase, But somehow all of the notes are broken and choppy. I'm using the GPO DXI plugin (I don't know if that has anything to do with the problem) with Cakewalk Music Creator 2002. All of the flute ensemble instruments sound great, but the vibrato instruments seem to be misbehaving.
Any help of advice would be of great appreciation.
