Not exactly, only 1/3 channels sound like the SID "warble" sound but you have to sit and think what does SID sound like.
.... which is simply a result of the "cheap noise" creating. You have to keep in mind that POKEY was the 1st chip.
It is not a problem to say "this chip sounds like SID", if it is built to sound like SID. But it isn't. It is just one of the variations, the original 197x POKEY can produce. Actually, If people hadn't slept well back in that time, the title music of "Starraiders" could have been sounding like one of the videos above.... or all the other "testtunes".... years before SID.
Problem is if you take three tunes, one from Hubbard one from Galway and one from Whittaker they almost sound like they are running on a different computer. I tried to cover the diversity with the 5 videos I posted in your other thread.
The tunes are just some "reference" depending on the known sounds and music style...
My only real reference is the Panther/Sanxion and Warhawk tunes I have heard and those three don't even sound as close to SID music as the VIC 20 SID VICIOUS SID emulator playing Rob Hubbard's Commando title music that's my point. The two chips work in a different way, Pokey is not a 12 oscillator phase accumulator design.
I don't like the sounding of the A8 versions there.
And still the old argues.... ofcourse SID is a newer chip, built on the available chipdesigns and with better technical environment. That's why SID has it's regions, POKEY cannot go to.
But, as you might have realized, POKEY has several sound generators and they can be switched/overlaid together in different combinations. The biggest flaw with POKEY is still the real bass generator, of which I sometimes think, the creator of POKEY had no idea of capacitive actions in electronic circuits. Same with the creator of GTIA... being not aware of anything outside NTSC...
You can't make a Yamaha DX7 sound like a Mini Moog synth, you can do similar sounds but not identical, same principle here. This is why I don't think this is the road people should go down. Ditto for all the ST SID players (Xenon 1 music on ST is nicer than C64 sometimes!) and the C16/Plus4 ones.
But you can always use some balanced sounds... in volume and frequency range.
I think it's best to work around the native features of the chip than emulate another chip, you need 1ghz x86 CPU power to run reSID in an accurate mode on Win VICE C64 emulator. Even then it will never be identical to SID. and that's with 1000x more CPU speed thrown at the reSID sound emulation module.
The most ridiculous part is that I'm only using the "native features" of POKEY.
And, sorry for being rough, but how can an emulation sound "100%" correct, if the SIDs
sound different (from slight variations to real music changing functions) at all.
