I found this bug long ago while DC7 was still going. The attached NSF shows that songs 8, 9, 10, 11 and 13 are broken, by what I think are the DPCM samples. The FTM files work all okay, but the exported NSF breaks if a specific sample appears(I think it's the one assigned to A#6, and perhaps others). I'm attaching the FTM just if it's needed.

EDIT!: Also, song 3 doesn't play the Namco 1 channel in frame 01.
EDIT2: But I just found that VirtuaNSF doesn't play it. In NSFPlay it sounds like a super-awful-distorted wave, which as long as I know, is not defined in any of my instruments.

I have the same problem with my Super Metroid project, I've asked people to help find a solution, but they never responded back.

I tried deleting the offending row in #8 and the rows surrounding it, but the NSF playback still halts.

FamiTracker acknowledges/reports the correct amount of frames/patterns when exporting the NSF, but you certainly never get to hear them.

There's some dark magic at work here.

This problem is related to [url=http://famitracker.com/forum/posts.php?id=4396]this and I've made a fix so it will work in the next version.

I was having a problem too. I believe it's related to this.

I was making a DPCM instrument and I used a lot of samples.

After a while, I noticed that the exports break, and that in some songs, the song freaks out and glitches when it plays certain samples. It seems to happen when I add a lot of samples.

I had a project with multiple songs and the song breaks on certain DPCM samples being played, but when I isolated the track and exported it alone, it seemed to play fine.
