How to adjust CC1 of multiple tracks

I’m still quite new to this and struggling to adjust CC1 modulation - especially when there are several tracks that all need to be adjusted so they sound right relative to each other. Any tips for this?

More specifically, I don’t know how to edit multiple tracks at the same time. e.g. if I want, say, the violins and flutes and clarinets to be quieter but maintain their relative volume, is there no way to bring them all down by the same proportion at the same time rather than adjusting each of them manually one at time? This can be very time consuming when there are multiple tracks (not always the same selection) that need ongoing incremental tweaks but i can’t find a way to see or adjust more than 1 curve at a time in the Key Editor.

Hi,

You can do this only in the Project window. So you can either write MIDI CCs as an Automation or you can open In-Place Editor.
