you must have jack up and running before you can even think of creating a linuxsampler client device.

are you sure you have that right? most probably jackd cannot be started because the alsa device is already in use.

cheers

I do have jack running.

i don't really want to pesk on you, but have you check the other probable reason, something owning the alsa device?

usual suspect might well be pulseaudio.

Got it all working. Gig samples work . SFZ is working had to raise Frames /Period up in jack. Was trying for to low latency. Amazed u can get gig and sfz happening at the same time. Thank You

you shall thank to whom deserves, the linuxsampler team. although i've been stepping on some shoulders back in early days, and qsampler was indeed the first gui front-end to the beast, real (grunt) work about gig, sf2 and sfz engines, is actually being developed by other giants.

now's time to consider for donation, don't you think? other than money, knowledge and experience is often valued ;)

thanks anyway.
