That's true, but I like the possibility to adjust these 4 values directly with the MSX. Every PC soundcard provides such settings, too, so why not the MSX.

One could choose to have it, as long -but I'm merely guessing the future- as people don't use such treble/bass/spatial settings to correct an incorrect tune in, say, a demo or game. E.g. demo or game with an mp3 should not require this extra chip in order to feature correct sounding music. In that case this extra chip is merely a personal choice.

I agree with wolf_ that mp3 sounds don't really need treble/bass/volume adjustment from a software point of view. If I'm going to buy one, it would definately be without these features and leave these features to my amp and/or speakers.
[edit]
Okay, I'm already changing my opinion Smile Because it could be nice to have a fade in/out feature in games, instead of chopping off the music and starting a new song. But I don't see a good use for treble or bass adjustment yet.

I also absolutely agree to wolfs last post, software must not require this additional feature. But I want to have it Tongue

Hm.. so, to fade in/out music (or just change the global volume anyway), do you NEED that extra chip? Or can fading/volume also be done without that extra chip?

Another thing of interest:

Can this main chip also playback/loop OGG?

There's this issue about MP3 concerning loops. AFAIK MP3 can't loop without a small hickup, whereas OGG can. Naturally for games and demos, a seamless loop is quite important.

There is no OGG support mentioned in the document ( http://www.walrus.com/~raphael/mp3/MMC_version/vs1011b.pdf -> MP3 and WAV/PCM). Do MP3s contain keyframes? If yes, looping without hickups should be possible - but who knows...
After a quick look on the document again, I also couldn't find a "master volume" register, which you would need for fade in/out.

Hmmm.. to me it sounds somewhat silly to require a whole other chip just to change the volume, but alas.. I think changing volume is quite required for practical uses, it would mean that everyone's best served with the extra chip..

Wolf, you can use a external mixer for volume up and down, for example, simple volume controls on external speakers.... not? And I think you can do some controls by software...

You don't want external mixers/amps to control the volume.. Tongue

If a game or demo wants its music to fade out, and other music to fade in, then you don't want to be forced to use an external mixer/amp for that. E.g. a text on screen: "press space and fade out please" and after that: "press space and quickly fade in please" ^_^

If it was only for EQ'ing or the spatial sound, then we wouldn't need this chip, but volume is so essential that we can't really be without it.. *unless* volume can be done with the first chip, then we don't really need the 2nd chip..
