I am running Pro Tools 10 on Mac OSX 10.7.5.
I have Arturia Spark as a Plug In on an Instrument Track.
I noticed that when I mute the Instrument Track containing spark, my other Pro Tools tracks are at normal volume. (I am just using Pro Tools virtual instruments on all of the other tracks). However, as soon as I unmute the Spark track, all of the other track's volume is reduced. Then I mute the Spark and track and the volume comes up again.
Then I noticed that when I pull the fader down on the spark instrument track, the volume of all the Pro Tools tracks rises. When I push the instrument track up, all of the tracks decrease in volume.
My mind is blown.
Is this a Pro Tools Issue or Spark?
