I want to play sounds from a folder with readsf~.
How can I make it read from the folder it is in, in order to be able to play it in other computers with different paths?

For example /Users/.../samples/Piano_Samples/$1-Stein.wav works fine but only in my computers.

../samples/Piano_Samples/$1-Stein.wav
or
/samples/Piano_Samples/$1-Stein.wav
or
samples/Piano_Samples/$1-Stein.wav

doesn't seem to work.
Any ideas?
