[CM] midi problems with cm3.10.2 on linux

[Nikolaj Tollenaar]

Hi,

I am having a specific midi problem with version 3.10.2 (as opposed to 
version 3.9). I am running linux mint 18, using fluidsynth over alsa.

When I start Grace, this the terminal output:

Common Music 3.10.2 [Config=Debug]

This is the Grace  console output

Warning: Midi output device FLUID Synth (qsynth) does not exist.
Warning: Midi input device Juce Midi Output does not exist.


the strange thing is, that qsynth only pops up in the midi connections 
(Ctrl-M) under input connections, whereas in Grace version 3.9 it only 
pops up under midi output connections, as it should.

Am I doing something wrong?

Greetings,
