If ASID XP plays it properly then my version will play it properly as well, if you set the flush mode to ASID XP ;)

How do you set the flush mode to ASID XP?

I'm forced to use version 0.1 of your dll, as the the newer version tries to blow up my processor!

I think you are referring to 'Hot_Mommas' by 'Jammer' (see my reply #11 above) and I believe it uses some clever ring modulation and possibly changing filters. No PCM samples at all at all. It is totally awesome though eh!? I love it. I tried playing that particular tune back through ASID XP and then muted each channel in turn and it seems one of the channels controls the shape of an oscillator on another channel. Or something.

Thanks a lot for the reply, i really appreciate it!

I think a skipped over a lot of posts just to get to the videos, hehe!

I'll try to get it cleanly into VICE as just another sound output option. VICE is pretty modular.
Of course I have to fix a lot of stuff first.

PCM playback is never going to work with this protocol, and even with another protocol there's still an awful lot of data to be sent over midi.
Most routines seem to write every 120-200 clockcycles to register $18.

And most sids that don't play back properly now is because it writes more than once to a register, which the protocol doesn't support (except for two writes to the gate registers).
And another possible problem might be that the delay between the writes to the registers is lost as well.

Great link.....and the man himself explains it in the last post. It is oscillator sync and not ring-mod..... clever stuff indeed.

PCM playback was more than wishful thinking on my behalf.......

I guess PCM playback would be possible if the sid file was played on an SD Card, and a special sid player app was written for the core.

But that would be quite an effort.

[TK.]

Problem: STM32 hasn't enough internal RAM for a proper C64 emulation which is required to playback a .sid file.
Possible solution: dump any SID register change and delays between register writes to a file - this can be streamed from a SD Card and forwarded to the SID(s)

The same mechanism can be used to playback samples.

Best Regards, Thorsten.

Now that's timing - I am just implementing exactly that ;)

Thanks a lot for hacking this into sidplay2! Some SID files from HVSC aren't playing perfect (or not at all, like 'Mutants' from Fred Gray), but it is fantastic to hear the music from that neat little box. Dear 8580, you have a 2nd life :-D
