I assume you want to use sfz. In this case create a text file somewhere which
you will fill with NKSP script code and link that script in your sfz file with
the 'script' opcode:
http://doc.linuxsampler.org/sfz/script_opcode/
The advantage with the gig format is that you get immediate syntax / error /
warning feedbacks while typing the script in gigedit's script editor. So this
is probably more convenient and faster, especially on first steps.
However alternatively you can also use 'ls_instr_script' from the command line
to check your script for errors:
cat /some/where/foo.txt | ls_instr_script sfz
Additional options are described by:
ls_instr_script

select $n
case 0
play_note($EVENT_NOTE + 2, $EVENT_VELOCITY)
case 1
...
case 2
...
case 3
...
case 4
...
end select
I don't get though what you mean with "repitched to the original note's
pitch". Do you want to start it with a x semitones offset and let it slide to
the original pitch within a certain duration?

The function is called change_tune() for some reason (KSP invention):
http://doc.linuxsampler.org/Instrument_Scripts/NKSP_Language/Reference/
change_tune_function/
And you would probably want to use it in conjunction with change_tune_time()
to control how long it will take to perform the tuning/pitch change.

Yes.
This tour is probabably a good starting point:
