Is the Speed supposed to range from 0x0 to 0x20 or from 0 to 20? I couldn't figure out why a piece I wrote in 0.3.7 had some severe tempo issues when I exported it as an NSF until I opened it in 0.3.8b and saw that the same problem occurred there.
i dont know if this has been fixed but, any time i close famitracker when the music is playing it glitches the sound and it sounds like if you were to hold the play button [enter key]
Minor Bug: Whenever you use 6 or less N163 channels, a popping noise will be heard at playback. I have an example FTM here that demonstrates this.
You can clearly hear a "pop" when you press play. This is only present when you play a song and it never occurs in a song again, but if you were to play a song in the middle of a pattern, it would be there.
Happened to me too, for example I wanted to mimic PWM so I had 16 waves of different pulse widths. I spammed V00, V01, V02, etc. but I could only hear a 3.375% pulse wave.
