One of my customers complained that after making input changes to their Yamaha DM 1000 model audio board they would be lost when they initiated a scene recall. This audio board has two different save methods and each method parcels out different portions of the audio board to be saved. The main one is “scene” which includes mainly production type of changes the board operator might want to configure for each production. The second save method is “library”. It includes deeper factors like input and output patching. The trick is to configure both scene and library and link the two. The board is set up so when you conduct a scene recall from memory, it also makes changes specified in the library save. The customer just needs to remember that when you do a patch change, also conduct a “library” save and lock it to the “scene” that you will be using.
