I recently got a FaderPort 2018 and I'm using it with Studio One.
It's good I can change track's volume with it, but it would be super good if I could edit audio item's volume as well (that what happens when you drag the top of an audio part). These mouse adjustments are just driving me crazy, but for FaderPort it's the ideal use case.
I mean, it's really weird that this isn't supported, but asked the support team and their answer was: it's not, go create a feature request. So posting it here now.
