logic pro x grouping tracks issues
Hi There. can any one tell me, I've grouped several tracks together in logic pro X a combination of software instruments and audio. However in moving the volume fader of one track I expect all tracks in that group to move in correspondence, some tracks respond and some tracks do not. I have tried this with each individual track and again some tracks correspond with each other and some do not. Would anybody know as to the reason for this am i missing something which i don't think so because all tracks are linked or is this another bug in logic.
Thank you in advance for your responses.
