VST Expression

I thank Tacman7 for its help;

Like what instrument are you using?
I try to answer.
For exemple : Concert Flute (EASTWEST Symphonic Orchestra Volume 2 Woodwinds)

By identical swiftness are you talking about velocity?
Yes, velocity

VST expressions are continuous controller messages?
These are « Expression Maps »

Which ones?
For exemple : SFL Keyswitch C0-F#0.nkm
C0 – sustain vibrato and F#0 legato with mod-wheel control

Sounds like you would need to lower the velocity on the ones that are too extreme.
That’s it the first problem. All these “Expressions Maps” are in the same MIDI track. How do we balance the sound levels?
The second problem: it is then necessary to follow the indications of nuances of a score

It is very complicated. I did not find a tutoriel to manage intensity in a work of orchestration in CUBASE.
After all, it is not better to place a single Expression Map in a MIDI track? If we use 4 Expressions Maps, to place 4 MIDI tracks for the same instrument?
