Hi Noel and thank you for your assistance.
I`m familiar with the highlighted buttons t change between the instruments, thats why I came to pedal steel and realized, that it`s the only instrument with the midievents shown, also it is, I suggest, real instrument, and changeing the events does not affect the chords beeing played- I know, how could this, if its played on a real instrument, but why then show the midi events? Ok, it`s helpful in the way, that one could learn playing the steel guitar.....
First time I suggested it must be a very good midisound and beeing recorded may be by a midipickup on a steel guitar. That would have been nice!!!!!
I want to understand, what I´m working with, thats why I`m asking for.

The bar settings I also know how to silence, but can`t get a real good intro or ending. I suggest, I have to play a melody on a keyboard and record it to the song, so there would be a "following" by the programm itsself.

By this time, I couldn`t find out, how to place an event (note) manually into the grid/piano roll a.s.o., also I can`t hear a sound when clicking on the keyboard, that is showed on the left side of the piano roll.
Maybe I`m too stuck to the way how it`s in Cubase done- just click mouse button and hold to the lenght of the note.
