FamiTracker
I noticed this a little while ago when making an NSF of the Scriabin Piano Sonata, but didn't look into it more until just now. After a careful inspection of the pitch tables and how they sound, I've noticed the playback frequency of the VRC6 saw is off by 1. In the attached example, E-6 at P80 should actually be the same pitch as the square E-6 (in the pitch table they share an effective greatest common denominator 14*16). However, in FamiTracker 0.3.7 we only hear this if I put a P7F on there to increase the frequency value by 1.
In VRC6.cpp, line 113:
Counter = Frequency;
Should be:
Counter = Frequency + 1;
The pitch tables are actually fine, and the exported NSF will match them as they should be. This is only a problem with FamiTracker's playback. (I can check in this change if you like, jsr.)
What this means is that, especially in the high register, VRC6 Saw will sound slightly more in tune with a P7F (in FamiTracker 0.3.7) but if played by an NSF player, you'd want to keep the regular pitch (P80).
Nice find. I've noticed this too and, as you said, it's definitely only a problem with Famitracker's playback (exported nsfs work fine). It'd be great if this could be fixed come the next update.
You can transpose it down to E-2 if you like. That's the next lowest place where the scales actually line up on a GCD. (The effect is subtler though; being off by one in that octave is much more slight.)
Thank you so much for this fix. Most of my songs are VRC6 and I kept thinking I was spending too much time on Famitracker and that my ears were starting to fail me. I honestly freaked out a few times thinking something was seriously wrong with me. What a relief.
