Which 6581 revision...

Hi!

Which -> 6581 <- revision sounds best? Which one has the best sounding filters?

I've had different revisions of 6581 but for many years I've used R4. I prefer the filters it has. both when talking about the cut-off range and the sound of the filters... they can sound so warm and yet you can also do cool things with the saturation.
I've heard other revisions that have lower cutoff range, which I think is too low... but still any 6581 filter is (to me) better than 8580. The filterrange is so odd and not logic at all on 8580. the cutoff is generally too high... just going one step up (using highbyte) is too rough for most standard music players that don't use the lower bits of the cutoff.

The best one is just... 8580. :> $5 and $6 waves sound nice and let composer create more (unusual) instruments. Old SID doesn't support AND between waves and it's in my opinion the biggest sin of 6581 chip.

Filters? In old SID they are so subdued... Yes, I know that a lot of scene people love them. But why?

Samples in 8580 are hardly audible, but this bug may be corrected by (seemingly) simple chip modification.

So there's no reason to use old chip.

the cutoff is generally too high...

It is advantage. Take a look at this tune: http://www.c64.org/HVSC/VARIOUS/S-Z/Shogoon/Timsoft_Intro.sid - this is model of great new SID bass. :)

Funny, I find that the bass sounds the best on a 6581 of the song you linked to!

Sounds best for you. For me sounds best under 8580. So it's rather subjective feeling.

Besides that, under old chip you don't hear intro lead in this Shogoon's zak.

PS. Sorry Laxity, I've sent you private message because of little mistake. :]

Depends on what you're used to, I suppose.
I'm a 8580 fan because of its magnificent highpass filter -with proper settings, it somehow boosts some frequencies above the cutoff point instead of sucking out below it. Which can be helpful in drum programming, if you set the filter resonance & cutoff (highpass or highpass+bandpass - the latter sounds even better) to certain values ($F, $02 for bassdrums, for example).

Ooo, man_who_knows_five_sounds (a, a#, b, c, d)?

Murdock, have you learnt how to create own instruments? Because your all "tunes" have - what a miracle! - stolen instruments. Sometimes not only instruments:

- Murdock's "tune": http://www.c64.org/HVSC/VARIOUS/M-R/Murdock/Intro_Zak_Remix.sid
- Touldie's song: http://www.c64.org/HVSC/VARIOUS/S-Z/Touldie/Intro_Zak.sid

We "laughs", too.

Well.. I've tested around 20 6581 R2 and R3. I haven't yet compared them to R4 or R4AR as I don't have any of those :(
But, so far it's my distinct impression that the R2 generaly has a lower cuf-off frequency than R3. I have one R2 with a distinctly more relaxed filter though.
One of the tests I put them through is Lightforce and so far the only chip that plays it (almost) correct is the R2 with the higher cut-off. All the other ones simply miss the really high-notes. However the other R2s can make a really cool bassssssss! ;-)

8580? ..oh it simply cannot compete with the charme of 6581... :-P

@jeff: is it an R4 og R4AR you have?

SIDDER: fuck you! you even are not a real scener so stick up into your emulator baybe.

We all real sceners started from something. Alot of composers used others tunes to compose their own or simply to learn how to compose. But of course you don't know that because you are not into real scene (and also HVSC doesn't mention about that sadly for you). No need to explain why the remix of Touldie's song got released. I confessed everything in my music collection (or STIL in hvsc) so your post is useless.

And since which time you are "we" ? Back off simply!

I for one am in the 8580 camp. Maybe i'm biased because it's the one i've allways had since i was a kid, so the more "muddy" sound (intentional provocation) of the 6581 just sounds wrong to me. :D

While playing around with sid chips in emulators, it has even surprised me that old tunes which was obviously made for the 6581 very often sounds much better on the 8580! The filters sound totally different, but they get a grooovy electronic feel to it imo.

(yea, ok - this was totally offtopic subjective shit)
