That is what I do for the Hollywood Brass yes and Strings or Winds if I were using them. I've seen a number of threads you've started in relation to this and Expression Maps. Using Hollywood Strings as an example would be a good idea since the switching is, as you say, over patches. I would suggest you also experiment with making a completely different Expression Map for the KS patches in Hollywood Strings to know how the output from the map differs. Very pertinent is that you have 4 columns and can define each unique entry in a column as attribute or direction. This is useful because there are certain articulations that are momentary (attribute) like staccato and others that encapsulate a phrase (direction) like legato. This way you cam program less changes with expression maps. For example, try: Make a Hollywood Strings instance with Staccato on channel 1 and a legato slur on channel 2 Create a new expression map for the track in Cubase and make 3 slots For the first slot call it Staccato and set it to channel 1 Set the staccato symbol in column 1 and set that as Attribute in the lower right Call the second slot Legato, set it to channel 2 and create a legato symbol in column 2. Ensure the legato articulation in the bottom right is set to Direction Name the third slot Staccato + Legato, set it to channel 1 and add the staccato symbol to column 1 and legato to column 2 Write a quick part and you will notice the groups are not exclusive, so you can say the entire part is legato except for certain notes that are staccato A final note is that the top slot in an Expression Map is the default and is what is used when no other articulation is found within a midi part (or when Cubase first opens). Apologies if I just explained something you already knew.
