Some soft synths (e.g. Komplete, Garritan, and a few others) do not keep volume settings. This results in their sounds far too soft to be useful in a mix. I have not found the problem yet with Presonus' Presence sounds.

I tried to use Studio One's Macro's - they don't make a difference.

Screenshot 1: Studio One Console view.
Channel on far left is Presence. Note fader more or less in middle.
The next channel is Garritan Aria - full blast, yet the sound is still too soft to use/
Far right channel is Native Instruments' Komplete. It must also be set very high to be heard.

Screenshot 2: Garritan Aria strings.
Volume setting is far right, third row of settings. While rolling, I can adjust it here, and then it sounds great. The moment I re-roll, it jumps back to its original setting.

Screenshot 3: Komplete
Volume is on far right, third row of settings. Notice it is about at a third. While playing, I can adjust it, but on re-rolling, it jumps back to this position.

In previous music software I used, I could get into a MIDI editor and check of CC7 is set ok. I can;t find anywhere for this to be done in Studio One.

Any suggestions on how to fix this? If it were only one plugin, I guess the problome would have been there; but several? Yet, strangely the Presence plugin is fine.
