First of all, hello, I'm new to the forums, but have been goofing around with Famitracker on and off, for the past few months. Recently I have been working on covering a song from an 8-bit themed flash game.

A strange glitch popped up today in frame 04, in Pulse 2, near the end, there is a note sequence which should follow the same volume envelope. A few of the notes sound very quiet, when they shouldn't, and nothing I have tried yet fixed it. The .ftm is attached. Thanks for any help.

That's because on rows 2E and 30, you have both pulse channels playing the same note, which causes a bad sounding distortion. Here, it overlaps at the correct time for it to cause both channels to sound quiet. If you apply a Pxx effect on one of the channels, that should keep it from being silent. P80 is the default value, so P7F or P81 should work. I attached a fix to show you what I meant. Look for the Pxx effects in frame 04.

Thanks. I wasn't aware that using the same note on both pulse channels would cause glitches like that.

This happens because the phase for each channel depends on earlier notes, and the sound is cancelled out when both channels happens to be completely out of phase. Both channels must use 50% (or 25%/75%) and the same pitch for that to happen though.
