Try something like this:
LOAD INSTRUMENT '/home/per/GigaSamples/Scarbee - R.S.P. '73 - Classic.gig'
0 0 ERR:0:Unknown command.
(yes, the gig files on this Scarbee DVD actually have "'" in their names...)
This bug has been fixed in latest CVS version of LinuxSampler. Now you can use
escape sequences to accomplish loading of instrumens with odd file names. In
your case i.e.:
LOAD INSTRUMENT '/home/per/GigaSamples/Scarbee - R.S.P. \'73 - Classic.gig'
Beside the common directly literal escape sequences (\', \", \\, \n, \r, \f,
\t, \v) you can also use escape sequences as octal values (i.e. \132) or as
hex value (i.e. \xf2) representing the respective ASCII code of the character
