How to generate a Tambourine "shake" (or any "trill" sound) in MIDI file ?

[Ziad Gholam]

Hello to all 

I am using version 2.18.2

I managed to write tambourine percussion music ...

Although I did code tambourine "shake" as trill  ( tamb2^\startTrillSpan  tamb4\stopTrillSpan ) 

I do not know how to generate that tambourine "shake" in the MIDI file (generated at the end of the layout section ...) ?

On a wider scale, how could I generate the sound (in the MIDI file)  of a trill on ANY instrument or voice ?
