I'm currently trying to debug the issue with subversion FluidSynth and
Qsynth when meter display is enabled. I'm not getting a crash though.
I've tried both qsynth 0.2.6 and 0.3.1. Both of them appear to have
problems when meters are enabled, but no crash, just a message like:
fluidsynth: warning: Could not connect to any physical jack ports;
fluidsynth is unconnected
It would be pretty helpful if I could reproduce the same crash. Any
tips Rui? Is Qsynth using FluidSynth as a shared library or spawning it
as a separate process?
Regards,
Josh
