MT-32 mode seems to have left and right channels reversed but fluidsynth mode does not. It is easy to test with Wing Commander.
This is correct, there is no bug here (except maybe in Wing Commander). The 'drops' come out of the left channel on my real MT-32.
As for FluidSynth/MT-32 panning being opposite to each other, again this is correct. The MT-32 interprets MIDI CC#10 (panpot) as 0=right, 63=center, 127=left. It is believed that early versions of the MIDI standard didn't define what these controls should do, so Roland just went with this scheme for the MT-32.
Later versions of the MIDI standard (and therefore later devices released after the MT-32, e.g. SC-55) explicitly defined CC#10 to be the pan control and to interpret 0=left, 64=center, 127=right. You can verify this by comparing the MT-32 and SC-55 manuals and reading the MIDI spec.
Chances are that Origin just forgot to invert the panning messages in their MT-32 music driver.
