Hello,

  I's like to try Linux Sampler although right at the start there's a
lscp_client_create with connection refused.  System is Linux Mint 17
KDE, latest.  Qsampler is: 0.2.2-5 installed from package.  Thanks.

Try increasing the timeout value in qjackctl.
Another issue I found in ubuntu14.04 was caused by the default linuxsampler port, 8888.
(qsampler: View --> Options). It works for me at 8889
