I have a question relating to using instrument groups, sends and inserts.
If I have, for example, three instrument tracks (audio or VSTi) that all belong to a logical group, say “Synths”, then I might create a group track and then route all three to that track.
Now, let’s say I have a common reverb on an fx track that I am using to allow the instruments to share the same reverb space.
So I’ll send from each instrument track (post-fader) to the fx track. Each of the instrument tracks will have different fader levels, and I might have lower send levels on one or more of the instruments.
So this way, if the fader is moved, the relationship between that and the send is maintained.
At this point, I could not use the group fader to mix because the sends are individual sends from the instrument tracks to the fx track. So the fader needs to stay at 0 - otherwise this would result in either more or less reverb than intended in the mix.
I could use a VCA fader on the individual instrument tracks collectively if I wanted to control the level of the group but that’s only half the job.
Say now on the Synths group track, I want to apply some balance to the group. So I might apply very light compression or dynamic eq. This then changes the tonal balance but it might also increase or decrease the volume.
This is the problem, as the changes are not reflected in the reverb. That is, the sounds being processed via the reverb sends are now not sonically the same as the changed dry sound on the Synth group track.
I can’t use a send on the synth group track, as each instrument requires a different send level. And I don’t want to have lots of extra instances of the same reverb plug-in - especially when it’s supposed to be a common space.
I can’t take the reverb and route it into the synth group track, as that reverb is also used for other instruments.
I also don’t necessarily want to have the reverb also going into the compressor on that group channel.
So what is the correct way to deal with this?
The instrument tracks could be anything, guitars, pianos, individual drum tracks.
