I love how simple your Piano Roll is, but we as MIDI lovers need something simple that will speak our language. For example by intergrading FL Studio's Per-Note Automation & Parameters so we can automation each MIDI note within the Piano Roll .
As you can see from the video. FL Studio added "Note Fine Pitch" (totally different from Pitch Bend), "Note Pan" (totally different from Pan which automates the main pan knob/slider), and etc. . It's very flexible to us as MIDI lovers, but simple for you to intergrade into your Piano Roll in Studio One .
