I'm an occasional user of a Leapfrog 48 desk at a small theatre in the UK, and I have a problem with the behaviour of playbacks (aka submasters) that has been bugging me for some time and I wonder if anyone can help. The venue has a line of Chauvet Par-Hex 12 fixtures in the wings each side of the stage and in front of the proscenium that are very useful for colour effects in live dance shows. I program a range of colours into the playbacks and work them live during the show to change mood
