I just started using the JABB library. I like the instruments a lot and to try some out, I wrote a short salsa-like cue (not authentic necessarily, as others have pointed out, but it reminds me of Celia Cruz): http://www.boletta.com/salsa/
I'm a brass player myself, and I think the trumpets and trombones in JABB are terrific. But mixing at high volumes levels can be tricky, and I encountered a similar problem with the JABB library that I have had with the GPO samples. I know that the mod wheel plays an important role in Garritan libraries, so I always make sure there is a Modulation CC command manually set at the beginning of all tracks to make sure the volume is at least "on."
So I tweak around and get everything sounding great. The mix levels are just right, but if I close my Logic file, when I re-open it, most of the instruments are muted. No sound. In order to remedy this, I have to go to the Kontakt player, select the loaded instrument, and turn the virtual mod wheel up. Then the instrument's volume is restored, or it least it comes back to some degree. Sometimes the volume level is actually different than it was in the previous session.
I know others on the GPO forum have discussed this volume problem in the past. Why does the virtual mod wheel affect instruments which already have a CC setting for modulation? Does the Komtakt Player override automation settings in the sequencer?
Is there any way to get around this and keep volume levels consistent from session to session? Is there something I can do to prevent these volume levels from disappearing?
