Default How to automate/change velocities w/ Garritan/Aria routed to separate tracks

Hey guys, I recently purchased the Garritan personal Orchestra 5. I have it set up so each slot is going to a separate track.. i.e. the Aria Player is only loaded onto my main track, instrument tracks are empty.

What I didn't anticipate is that now, the way I've always changed note velocities in the CC lane does not have any effect. I assume this is normal behavior.

So, with this setup, how does one change velocities for individual notes? I cant believe it's not possible?

As an alternative I could put a separate instance of Aria on each individual track but I'm worried that would overwhelm the whole system? Perhaps not?

Any help or links to helpful videos are much appreciated!

The way velocity works isn't affected by the way you have the Aria Player routed. If the MIDI note is getting through to the Aria Player, the velocity is also.

I suspect your problem is that many of the Garritan instruments use Mod Wheel instead of velocity to set the volume of the instrument. It depends on the type of instrument. Percussive instruments (piano, drums, harp, ...) use velocity for volume. Non-percussive instruments (woodwinds, brass, strings, ...) use Mod Wheel. This allows you to crescendo/diminuendo those instruments, since you cannot change velocity in the middle of a note. If I recall correctly, the instruments that use Mod Wheel for volume often use velocity for attack timbre, but that is usually a subtle difference compared to the volume of the note -- so the velocity is probably having an effect, but it is not the effect that you are expecting.

There's a section in the GPO5 manual that explains how it works. The manual also defines which instruments use Mod Wheel for volume, but basically it's any instrument that in real life can crescendo/diminuendo during a note.

Hmm, that's very helpful and you may be right!

I did notice maybe a very slight change when changing the velocities, and that may have been the attack timbre you mentioned. So, for volume I would go into the CC pull down and select Mod Wheel and see what that does? And I can change the mod wheel parameter for each individual note, correct?

Yes.

Sort of -- CC events are not specifically tied to notes. You can have CC events that don't overlap any notes, and you can have multiple CC events that overlap the same note.

A common thing to do is to draw several CC events for the same note so that you ramp (or vary in some non-linear fashion) whatever parameter you want to change (in this case, Mod Wheel). For example, if I wanted to swell the note, I might start the note with Mod Wheel=64, and then during the note have Mod Wheel values 65, 66, ..., 79, 80, 79, ..., 65, 66, 64.


I see you are new to the forum, so it might (or might not) be a little early to introduce you to the MIDI CC tools that are available (for free) here: https://forums.cockos.com/showthread.php?t=176878
