Additional dynamics for MIDI

[Michael Pozhidaev]

Hello, everybody!

Probably, it is a well-known question, but I didn't find an answer in the 
manual at the first look.
Can I specify some additional dynamics for the midi output, but invisible in 
the page layout?

Actually, it would be very useful to have some 
universal dynamics for the layout and midi, some additional dynamics for the 
layout only and 
some additional dynamics for the midi only.

Of course, I can make separate .ly file for the midi output and specify 
required 
dynamics commands in it, but is there a way to do it with one single file?

Thanks!
