Yep! Check this page for info on how to calculate the freq depending on clock frequency:
http://unusedino.de/ec64/technical/aay/c64/sidmth.htm
...and by the way, I have a faint memory of once noting that the freq-table in JCH wasn't "perfect" in the sense of directly corresponding to the formula above. I may be wrong though, because I never really checked it. Just a... uh.. idea or something... that someone might find relevant or interesting. (After all, a "perfect" table is based on Bach's way of tempering scales, which means it is only "perfect" on average. That is, equally wrong for all different keys. A perfect scale for a specific key is not exactly calculatable in terms of BASEFREQ*2^(NOTE/12), even though this is how synths work etc.. ...so perhaps JCH's table is manually tweaked to sound a little better in common keys, or something. ..but you know people know this already, I guess, so I should stop blabbering now. :)

Why not tune other instruments to SID? :) Anyway never understood why it's a big deal, there's a lot of music that isn't tuned to A-440Hz anyway. Though I personally hope/believe GT has by now a mostly correct 440Hz table for PAL..
Btw. one shortcoming of 440Hz PAL table is that by the highest note (B-7) you run out of the SID freq.scale and that note is bound to be out of tune if it's just clamped to the maximum $ffff. |

Doh!.. Ok.. Makes sence that the SID outputs differently but I was hoping that it didn't (they forgot to inform about this issue in the Programmer's Reference Guide, I guess).. It's a little annoying.
The JCH table seems to be exactly the same I've always used in my players. And the one I used, I ripped from Rob Hubbard.. And since Rob Hubbard is god, it MUST be correct :) (B-7 being the exception though!)

Someone in the PRG or the normal manual they list the sound output depends on the CPU frequency. |

Oh, well.. Must have missed it!.. Or mayby I read it 15 years ago, but forgot all about it in the mean time. :) |

I just want to mention this is a great editor and player that is definitely worth checking out.
Just listen to the awesome tunes included in the download done by GRG.
Massive respect to GRG & GT for making such a fine piece of software.
Thanks !

Hi!
I totally agree with stainless steel.
But one feature is still missing: load/save support for MMC64.
That would be a very nice feature. Will you add this?

In a way MMC64 is quite an unfortunate device for tool/utility authors, it leaves (l)users expecting each of them to write lowlevel filesystem support :) |

isn't there some kernel load/save bios thingy? i mean, seriosuly, unless you need irq loading (ala dreamload), what the fuck is the point of every fucking program having to support it? fuck that for a game of ponies. |
