6581/8580
Is there some good reason SID music is not released with both 6581/8580 versions? Most tunes are only released for 8580 and some sounds play to low on 6581. Is there some way to convert 8580 tracks to increase the volume of the sounds that are too low on the 6581? |

Yes, using different lookup tables would go some way to make the same tune sound more similar across the chips. Only problem is that there is also a lot of variation between different 6581 chips for example.
Some of the variation can be seen here:

The red, Follin-style curve isn't even at the end of the range, zerozillion had a chip with CF ~1000 Hz at register value $0. 6581 filter curves be crazy. |

Yeah, that's true. I remember hearing that Martin Galway said the player for Terra Cresta originally had an option in which you could adjust the filter according to your own SID, but it was never implemented into the game. I wonder why nobody else has done that since then (to my knowledge). |

The menu screen of L.E.D Storm had this option from what I remember, whether it was documented in the manual or not.

I guess there are these cards which take both SIDs and you get it to play the tune on both the same time. Just choose the output. Solved. |

Would it make sense to have two official csdb 6581/8580 categories or tags? So one can filter and search on them? |

maybe no need for tags, since tunes got that in PSID info. |

Aha, so csdb could automatically fetch that from hvsc and display it?
Edit: I just realized it is displayed on the sid page, but not the release even if it is a music release. |
