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.
