To do a "swell" within a note

It depends on where you're getting your horn sample from...

I'm guessing you're using the EXS24 one from within Logic. In which case you need to assign the Mod Wheel to a volume parameter (It might already be done for you). Then fine tune the range so the down and up positions are at a suitable dynamic (if you want to get technical you can apply the cutoff frequency too so the note gets brighter as it gets louder). Lastly you need to draw in the swell/crescendo in the 'Hyper Editor' at the relevant position. To my knowledge this will not be represented in the score editor (nor vice versa if you tried that). There are lots and lots of other ways of doing this and like I said, it's partly down to the instrument/plugin you're using in the first place, but that principle will work.

Hi!

This is what I do; wether use track automation (volume) or simply go to Hyper draw-volume, set it to o and draw a line with nodes untill you get the db you want on the duration of the pitch. There are however more ways to achieve this.

Hope it helps!

The volume thing will work, but actual horns also change their harmonic structure as they play a swell in the real world, so you might also look up sending the horn signal to a bus, and on that bus, placing EQ which you can change over time, along with the swelling volume (probably adding both some bass and even more treble freq's).

Good luck,
