crescendo and diminuendo on the same note

Thanks for the pointer.

Now I have experimented a bit and it really is quite a complex of objects being addressed. My first experiment was in a lengthened bar (9/8) and after putting in voice 2 and making the rests invisible, I split the bar with the tool - split measure. That resulted in voice 2 being very confused (no longer added up to bar length) and the cresc decresc lines occupied the whole bar instead of where I had placed them. So I put them in again after deleting them and all of voice 2. Then the cresc line turned into dotted lines when I adjusted the velocity. And it stays that way on export. Is that a standard musical symbol? I have a professional composer in the family and she says - no. Also the lines failed to maintain position and changed strangely if I saved and reloaded the file. Using the inspector, I switched among staff, part, and system for the cresc, but it still takes place subito at the rest beginning the decresc. The design is a clever idea - but are the properties for cresc actually attached to the right object? I want them attached to voice 1 of the cello part on a particular note. It seems counter-intuitive to attach it to a hidden voice. Velocity type and velocity don't seem to make any difference to it. (testcresc.mscz)

I deleted the cresc and the playback was unchanged. I added it back and it is no longer dotted. But there is no impact on playback. I deleted the forte and reattached it to a different rest - still no change. Ah - adding a velocity change to the decresc resulted in a gradual decresc rather than a bump. Now something is happening. Also here I note that saving, closing, and reloading did not change anything. I expect that with additional bars, this might behave with more complexity. When I copied the bar back into the full score, the cresc-decresc became less than greater than signs and lost their shapely forms.

Very complex - intriguing - thanks for the help.
