There seems to be a crash in the reverb processing, but I cannot reproduce the problem by simply enabling reverb, so it might be the combination of several settings that makes it crash on your end. Can you please provide your mptrack.ini to have a look at?

PS: DMP files can be quite big (but are easily compressable), that's why only compressed files may be attached. I know it's not optimal that the software doesn't indicate which file types are allowed, but I didn't write it.

I can confirm that it doesn't crash without reverb.

It has something to do with the mixing quality. It was set to 96 kHz. With 48 KHz I didn't have a crash anymore (even with reverb).

If using 96 KHz for WAV export (Stereo, 16bit), OpenMPT crashes as well.

Yeah, seems like reverb does different things if the sample rate is above 50KHz. Probably because "back in the days" it would have caused too much CPU load. I still don't recommend using any of the internal effects like Reverb and Bass Expansion, but I'm going to remove the reverb downsampling anyway.

Revision 1479 should fix this, check http://sagagames.de/stuff/mptrack.exe

Works perfectly, thank you very much!
