[VRC7] about Changing of bulit-in patches and OPLL (YM2413)

[GOZAHAND]

Yes. I think Changing of built-in patch is no official so. and that is no more VRC7.

But I saw interesting video. Here is Link.

Someguy Changed sound chip of "Lagrange Point" into REAL YM2413(OPLL) instead of VRC7 chip.
and compared each sounds.

and I heard our FT's VRC7 built-in patches Not correct yet. (Still rainwarrior works hard try to correct sounds. Thanks to him!)

here is Original OPLL built-in patches.

00 user-custom
01 Violin
02 Guitar
03 Piano
04 Flute
05 Clarinet
06 Oboe
07 Trumpet
08 Organ
09 Horn
10 Synthesizer
11 Harpsichord
12 Vibraphone
13 Synthesizer Bass
14 Acoustic Bass
15 Electric Guitar

VRC7's that is have some difference.
01 Bell
06 Rattling Bell
09 Soft Bell
10 Xylophone
11 Vibraphone
12 Brass
13 Bass Guitar
14 Synthesizer
15 Chorus

Xylop. and Vibarp. are just changed slot.(Maybe)

But VRC7 discard Violin, Oboe, Horn, Harpsichord, Synthesizer Bass(Maybe?), Acoustic Bass(Maybe?), Electric Guitar.
and GET Bell, Rattling Bell, Soft Bell, Brass, Chorus, Bass Guitar(Maybe?), Synthesizer(Maybe?)

and Last, Anybody know Settings(Like modulator and carrier ADSR & etc.) of OPLL Built in patches?
I want to use them in VRC7's custom patch.

There are also the YMF281 and YM2420 which are 100% YM2413 compatible but with totally different patch sets(281)/a flipped register(2420)

This page has the register values for MAME's approximations of the YM2413's built-in patch set. I loaded these into the attached .ftm.

Note that some of the patches, including Guitar and Trumpet, have some differing values between FT's built-in equivalents and the YM2413 ones from that page. I don't know if that's because the MAME devs interpreted the settings differently, or because these patches actually differ between the YM2413 and VRC7. I assume the former.

Oh, This is Just what I need it!

Thanks.

NSFPlay has a setting in the ini file to select a YM2413 patch set, or a few other variant patch sets instead of VRC7.
