Expression Maps

In the Edit Playing Techniques there is a large popup list of playing techniques but for most new playback playing techniques are needed. So I go ahead and create the new Playback playing techniques in the editor. These are carefully named to be exactly the same as in the Expression Map. Am unsure if existing techniques in the Strings Panel like “pizz.” and “spicc” will link to the Expression Map or do something else—so created my own named slightly differently. Here is how I thought this would work: My expectation of the logic flow here is that if I created in the Playing Techniques editor a new technique Named “Patt Leg” with the Text for it also named “Patt Leg”. Then in the Playback playing technique I create a new technique called “Pattern Legato”-- which exactly matches the articulation for keyswitch “D1 Pattern Legato” in the Expression map–I would have thought that when I type “Patt Leg” in the score that this would trigger the “Pattern Legato” in the expression map and sound that articulation. Same name. This almost works some of the time. Another issue is the apparent need is to somehow initialise at the beginning of a part to“something” otherwise the part playback is the last utilised articulation regardless of what I have written. If the linkage between articulations in the Expression Map and those specified in the “Playback playing techniques” having the same name, is not the tie in, then how does it work?
