VRC7 Instruments - Lagrange Point
VRC7 audio has 15 presets and 1 blank / custom instrument available. Lagrange Point used a unique custom instrument for each song (I think it reuses one of them).
I found the table of settings and it actually contains over 90 instruments, so... most of them were unused in the game music. (I can't be sure they were never used). Anyway... I copied them over to famitracker files, if anyone is interested. Split accross 2 different files.
Here is the table...

Re: VRC7 Instruments - Lagrange Point
I had a hard time deciding what to name each instrument. You might disagree with my descriptions.
Also, I haven't got around to figuring out which song used which custom instrument.

Re: VRC7 Instruments - Lagrange Point
I actually did some work on this recently:
https://wiki.nesdev.com/w/index.php/Use ... 13_Patches
Also this thread:
viewtopic.php?t=23328
Interestingly, one of the Lagrange Point patches matches a built-in VRC7 patch. None of the other ones match anything else I could find.

Re: VRC7 Instruments - Lagrange Point
After looking into the source code of Dn-Famitracker... I noticed that there are multiple versions of the preset patches. You can switch between them if you click File/Configurations/Emulation/ then change the VRC7 patch set.
My question is, why are there multiple versions of the presets? Shouldn't this be a known constant?
If you look at the value tables, they aren't even close to each other. Are we just guessing at what the preset values are?
Which one would be considered "accurate" to the actual VRC7 hardware?
The one that Dn-Famitracker defaults to is...
https://github.com/Dn-Programming-Core- ... one_nuke.h
Which appears to be the same as the one one the WIKI (under VRC7 audio).

Re: VRC7 Instruments - Lagrange Point
They've only been "a known constant" for the past 3 years - before that, there were a bunch of different sets that various people had "ear-tuned" as close as they could get.
Clearly, the people who "ear-tuned" the presets didn't have very good ears.
Er, that one exactly matches what's on the wiki page...dougeff wrote: ↑Wed Mar 09, 2022 6:18 am Which one would be considered "accurate" to the actual VRC7 hardware?

Which is notably different than the table found on the wiki... in fact, every table seems to be different from the table found on the wiki (on the VRC7 page).

Re: VRC7 Instruments - Lagrange Point
So, to answer your question, the "Nuke.YKT" patch set is the definitive 100% correct one, and all of the other patch sets out there can be ignored.

Re: VRC7 Instruments - Lagrange Point
Because the initial guesses were wrong, but it was deemed better to let musicians choose which of the previous incorrect patch sets than to make them use older versions.

Re: VRC7 Instruments - Lagrange Point
Several revisions of the patch set were estimated over the years by different people. Since Famitracker existed for a very long time as well, when it got better versions of the patches, we still wanted support for the older ones so the music made with those patches could be still be played as it was originally composed.
Same deal with NSFPlay. I kept legacy patch sets because there's a lot of VRC7 Famitracker NSFs out there that were meant for the earlier sets. (...and PPMCK, etc.)
Of course you should use the real dumped set for Lagrange Point. Anything made by homebrewers, on the other hand, becomes an archeology problem.
I think all of us that made estimations were using the CopyNES' VRC Tuner feature. You make a change, and play it back through VRC7 as a custom patch, then you play the same note on the built-in patch, and you listen for differences, or analyze differences via FFT/etc. Over time we got closer and closer.
A lot of the values that "look" different aren't functionally different. Not all parameters do something meaningful at all times (e.g. modulator decay parameters that are never reached because of a short carrier envelope).
A lot of the things that were different, we could hear they were different, but it's really hard to guess parameters based on sound. Like if you have everything except the attack envelope perfect, you might easily hear that it's 4 instead of 5. If 2 or more parameters are wrong and they interact with each other (e.g. modulator strength vs. its envelope, or keyboard rate scaling, etc.) maybe any one thing you try changing makes it worse, and what you really need to do is change a few things at once. We also didn't know how to reset the LFOs before NukeYKT's dump, so any patches with LFO (a lot of them) were especially tricky to compare, because the start of a note wouldn't ever line up with consistent part of the LFO.
When the real dumped set appeared, I did a comparison vs. my last best estimate, broken down by parameter, if that's of interest:

Re: VRC7 Instruments - Lagrange Point
Interesting.
I'm pretty late to the game (and generally wasn't paying much attention) to VRC7 information.
I guess Dn-Famitracker is better than previous Famitracker versions, due to the corrected VRC7 presets.
Also, I noticed that you can play multiple notes simultaneously in the virtual keyboard, whereas earlier Famitracker versions, you could only play 1 note at a time.
I don't think the text export from Dn-Famitracker works with famitone (without editing the export). I'll have to look into that.
