Hello everone.....i am trying to make adjustments to rhythms such as volume and reverb levels for each variation....but for some reason only variation one and two allows me to edit....when i edit three and four and then ave it ...it just reverts back to what it was before....so i end up with say reverb 30 on variation 1 and 2 and then 50 or too much volume on 3 and 4....am i doing something wrong?
