TOPIC:

I was wondering if there is any way to have different volumes for each given profile.

Consider the following flow:

• Preset 1 is set to active, and the master volume is set to 0db
• The user activates Preset 2, then changes the master volume to -24db
• The user activates Preset 1, and the master volume is automatically set back to 0db
• The user activates Preset 2, and the master volume is automatically set back to -24db

This feature would be quite useful, especially if you have different outputs enabled on different profiles.

If you want one to be lower than the other then just reduce the level on the outputs rathwr than the master volume. 

That doesn't work if I consistently want to adjust the volume of Preset 2 while keeping Preset 1 at 0db (i.e. using Preset 1 for outputs 1 & 2 going into a headphone amplifier with its own volume pot, but using Preset 2 for outputs 3 & 4 going to a power amplifier that does not have a pot)

I've definitely used the trick you mention in other configurations, though.
