[LAU] Using third-party (commercial or not) .gig files with LinuxSampler

Hi All, Recently I've started playing with LinuxSampler + Fantasia front-end and I'm extremely impressed. I'm currently only using it to record Piano using the excellent free "maestro concert grand v2" .gig that you can download from the LinuxSampler website. I want to create a library of .gig files so I can have more sounds at my disposal and I was wondering about peoples' experiences in using commercial or otherwise third-party .gig files with LinuxSampler; How compatible is LinuxSampler in your experience(s)? Second, I have a rather extensive EXS24 library and I was wondering how doable a conversion of this libraries' sounds to .gig fileformat would be (are there tools to do this, can you do it yourself using smart scripting tricks, etc). Kind regards, Rubin Simons.
