How can I transform a NWC file in a MIDI file without loosing the dynamics and crescendo and diminuendo? Tks
Saving as a MIDI file (Type 1) doesn't effect anything, i.e. keeping all effects the same.
Not True! Certainly Fermatas etc don't work. You have to cheat and put in extra long tied notes to achieve this in the saved midi file.
There is a notice/hint about this. It's better (IMHO) to use local tempo changes, as proposed in the hint (cf the tips that can be displayed when starting the software).
It concerns both Breath Marks and Fermatas.
Note that for good play back in NWC, only one of them (vertically speaking) must be set with a value.
