Hello,

Today, I built linuxsampler from CVS in order to be able to use the SFZ
engine; however, when I do:
LOAD ENGINE SFZ 0
SET CHANNEL AUDIO_OUTPUT_DEVICE 0 0

LinuxSampler segfaults. Has any one had any success using linuxsampler
together with SFZ, ir is it still very much under development at this
point?
I've used it quite a bit, but I did find in the past (though less so now) that it's a bit particular about the order in which things are done. It could be that it's now happy enough with files generated by its GUIs (I use Fantasia, and haven't run in to these problems for a while), but that it's still not entirely robust when given commands in a different order to what it's expecting.
I've attached a sample .lscp file that I've been using a lot -- it was generated in Fantasia, and loads 10 copies of the same SFZ drum kit. Hopefully it'll give you some pointers on how to produce a .lscp file that will load successfully. 

Thanks
Leigh
