... plenty of classical music uses drums - and numerous other types of percussion -, and there are many techno/trance tunes which focus on melodies and not just on repetitive uninspired drum festivals (not specifically thinking of RZ or B&R here).

I'm sure you have understood what I meant - dominant pattern drumming like in rock music etc, which is not used in classical music because drumkits weren't invented at time.

I'm sure you know that 'techno' refers to many subgenres, but because we speak about Jesper Kyd, we speak about certain subgenre which has no focus on melodies. In any case, techno music is always repetitive, more or less.

I pretty much agree with everything you've said :) Can't say I'm a big fan of JKs style, but the B&R stuff is, indeed, pretty awesome.

It isn't really the output stage that's the problem, it's all caused by distortion present in the chip. Obviously there isn't any point trying to fake this, you need to get it right. It's the last part of the puzzle that I really need to solve, but it takes time and a lot of effort, and real life (tm) keeps tripping me up ;)

"low quality of the output stage" seems to refer to what a model #2 outputs. - I think you can fake it by just setting your emulator to a sampling rate of 22khz, or better yet: 11khz. :P

I don't understand meaning of this comment, as well I don't understand what reason you had to said obvious 'the rules has exceptions' in previous post.

The MD2 is what I'm thinking of chiefly--it had an audible noise floor compared to the original MD. Heck if you could modulate in some kind of 50/60hz (+harmonics) distortion at like -32db you'd have a big piece of it. Of course, another big part of the sound is the television's speakers it's being played through... I've also noticed, and you'd totally be the man to ask here since you wrote the best emulation of it--does a real MD have some kind of nonlinear volume curve? The only difference between Fusion and real HW that I've noticed (besides the overall cleaner sound) is that the dynamics of the audio seem to be wider than the real thing. The HW to me seems to have a more "compressed" sound... also, have you ever considered implementing some kind of sound plugin system? Something like support for VST effects, or even a custom format? It would be neat in that you could say, pipe the individual channel outs into a plugin, like a send/return effect, and let a user apply effects to enhance--reverb?--or degrade the audio if they chose. If you did something like that I'd totally take a crack at writing some kind of simulation. It wouldn't be accurate "emulation" of course, but neither is screen filtering. Just a thought, it'd probably be work :D

It looks like this is less of a technical discussion now and more one of musical taste :wink:

I'm always looking for teeny tiny looping samples as that's what you need for music on the SEGA CD if you're not using the FM or CDDA. The PCM chip in the CD is designed for teeny tiny looping samples. :D

I just never understood the point of having wavetable sound hardware and giving it no RAM to work with, haha... of course I guess that's like having full motion video with no decent color palette to work with either :roll:

Which I guess is probably why there is so much redbook audio on SegaCD games? I think though the biggest travesty was the Saturn's sound HW not really getting used properly.

the MCD PCM chip does not have forced interpolation in it so it sounds much cripser than SNES ADPCM chip :)

Sonic CD uses the PCM for wavetable music for the past and future. The present is redbook.

it does it only for past... at least EU version does.

Well, ONE of those time periods uses the PCM wavetable instead of redbook. :D

Anywho, if anyone knows of any teeny tiny looping samples, I'd be much obliged for a link.

The Past songs use PCM samples for the instruments. Get it? Past? Supposed to sound older...?

By the way, the most accurate SPC player can be found in this thread: http://www.hcs64.com/mboard/forum.php?showthread=14893

It sounds much better than anything previously. (SNESamp, etc.)

Never thought of it that way. I guess that's why you're the SmartOne.
