NWC Viewer Soundfont Crash

2017-09-10 05:33 PM

I have observed the following issue with the NWC 2 Viewer 2.75.a.2. Upon further testing, it seems to do this both for regular NWC scores and for MIDI files. I can reproduce the issue at will, when you do the following steps in the specified order. This assumes that soundfont FluidR3_GM has been previously loaded (because I can't find a way to "unload" a soundfont).

Run NWC 2 Viewer
Go to Tools > Options... and select Play back device of Microsoft GS Wavetable Synth
Open a typical score (I used the sample "Anchors Aweigh")
Click the Play button, and confirm that it plays with the GS Wavetable synth (and sounds cheesy)
Go to Tools > Options... and select Play back device of <Internal: FluidR3_GM.sf2pack>
Click the Play button, and confirm that it plays with the soundfont (and sounds much nicer)
Go to Tools > Soundfont... and rechoose the FluidR3.GM.sf2pack sound font file.
Click the Play button. There can be one of two outcomes: you will either get no playback, with the music scrolling by, or the program will stop working.

I am running Windows 10 Version 1703, 64-bit

Is anyone else able to reproduce this, or is it something peculiar to my system?

I dont have the FluidR3.GM.sf2pack around (should it have been installed with the Viewer? where?).
But with the (my) regular FluidR3 GM.sf2, it has now worked beautifully and without problems 3 times ...
I am running a 64bit Win10 Enterprise 1703.

~~I have not yet been able to reproduce this.~~ I have been able to reproduce this on another machine (Windows 10 x86). Looking into it...
