Low sound in ZynAddSubFX

Having trouble with LMMS? Ask about it here.
I've made custom presets for ZynAddSubFX. When I load a project with them, they come out sounding like this: https://www.dropbox.com/s/m68fqj5vihsr2 ... d.wav?dl=0
I can fix it by reloading the preset again, but it breaks if I try to edit it.
Any help would be appreciated.
Dont know if this is your answer, but
if any instrument gets really low, it is often because the midi-velocity has been changed
Go to the midi-tab, and reset custom-base-velocity to default value: 63

If you make an instrument-preset, and it is sounding 'nice', but just have too low volume, you may like to do like this:

Thank you very much for the tip, but the velocity already was 63. I tried toggling almost everything ‒ guess I'll have to file a bug report now.
I usually turn my velocity all the way up to 127, and let the keyboard do the rest.
@x16 -what lmms version do you have. Current PR is bugged in respect to zasfx, and will crash
I have 1.0.0 on Ubuntu. 1.1.0 isn't available on apt-get or the software center. I'll try and install it later then.
Update:

The GUI seems to be crashing the whole deal. Re-installing LMMS doesn't work. Reinstalling zynaddsubfx doesn't work. When LMMS is run in Terminal, returns

Code: Select all

QtXmlWrapper::loadXMLfile(): empty data 
RemotePluginClient::shmget: No such file or directory
QtXmlWrapper::loadXMLfile(): empty data 
RemotePlugin::DebugMessage: failed getting shared memory
The problem definitely seems to be the GUI here. I don't know what caused it. Before, everything was running well and I didn't run into any problems.
you need a linux GURU -Thats definitely not me :/

For some unknown reason shmget is not defined in your configuration, so it's not using shared memory. Causing the crash.
Thank you for the help. I compiled lmms myself and now everything is running smoothly.
