lmms not working with rt jack; vst and midi

Hi,

 I'm experiecing problems using lmms. I didn't use it before so it
might be related to wrong settings.

1. lmms doesn't run with rt mode enabled in jack.

   The terminal says:

   "cannot lock down memory for RT thread (Nicht genügend
   Hauptspeicher verfügbar)"

   This is strange as the computer has 20GB of Ram and only 2GB are
   used upon startup.

   My /etc/security/limits.conf says:

   @orm	-	memlock	unlimited
   @orm	-	rtprio	99

   lmms is running with the "orm" userid.

2. Using a VST plugin (The Demo version of the Legend by Synapse)
   creates nasty audio dropouts when sending pitchbend or other
   continuous data while playing (with both, the ALSA or JACK non-rt
   output). The dropouts are clearly related to the incoming Midi
   (which is using the ALSA Sequencer interface). The cpu load is
   around 38% when playing and doesn't change if continous data is
   received. If it was hardware you'd suspect that midi in and audio
   are sharing the same interrupt...

   I know this might be a problem of VST with wine in general or
   something related to the way the synth is programmed but with these
   clicks the plugin is basically unusable with controllers and maybe
   someone knows ways to circumvent this problem. The VST plugin seems
   to be executed by this process:

   /usr/lib/lmms/RemoteVstPlugin.exe.so \
   /tmp/{3e7dc1eb-ba62-4900-9b5f-ec04d555ec23} xembed


BTW (regarding versions): My arch system is up to date.
