Well this is a bit unusual... I sort of just covered a song from a video I randomly found from a related video of my own video. It's the 4th song in this video:
[url=http://www.youtube.com/watch?v=tMg_zrrIviU]http://www.youtube.com/watch?v=tMg_zrrIviU

I just thought it was very calming, and I... covered it... for no reason... Yup... Enjoy...?

EDIT: Also I guess I'll add a custom song I made. I used arpeggios on the FDS channel, except not in the usual way, take a look at the instrument >:D.
I didn't intend to make it into a song, but it just sort of... happened.

That's a neat trick!

If you want to make this FDS arp work outside of FamiTracker (i.e. exported NSF) you'll need to adjust it slightly to compensate for FamiTracker's improper FDS modulation implementation. (Will be fixed in next version.)

I've attached a version that won't sound right in FamiTracker, but should export okay.

1. Reset value at beginning of mod table. (FamiTracker's auto-resets for some reason.)

2. Use two high entries instead of one to compensate for a difference in scaling. (Famitracker is about half?)

The reason it works is interesting. Modulation width on the FDS is relative to the starting pitch (which is why it's the same chord on every note), but the actual change to the frequency is linear (in Hz) proportional to the mod value. Coincidentally the high table entry with mod value 63 corresponds to approximately a 50% increase in frequency, yielding tones from the harmonic series (e.g. E A C# above your A-2, which are the 3-4-5 harmonics of A-1).

I was actually pretty surprised it made a real chord, I would have totally expected 3 notes that didn't go together at all. That's all pretty neat.

Any idea when this new version is coming out? I feel like it's been pretty quiet...

Sweet.

The high pitch tringle in frame01 reminds me so much of one of the Skate or Die games. :D
