2SID competitions.
Hello everyone.
I've only noticed for while that some various people are now starting to work on these 2SID (6 voice and 2 filter) songs. Although not as popular as standard SIDs, I believe these are quite fun to do, as you have more flexibility to include more than one filter and play more than one instrument which needs two voices, such as the $57 vocal trick for example.
Of course not everyone has a real c64 with an extended SID, but in today's world most people now use an emulator for quick viewing on music entries, which of course the emulators now have the option to include double SID emulation.
Up to now, it seems that Silesia Party in Poland will be holding the first 2SID competition ever in the scene. Would it be a good idea to start these 2SID competitions in general? Similar to those current SID compos that CreaMD usually holds, a 2SID section could be held as well.
Afaik, GoatTracker 2.61 Stereo is the only available music editor to compose these 2SID tunes, but soon there may be some similar editors on the c64.
What's your opinions on this? |

I think the main problem with stereo SIDs is that they all seem to require the second SID at a different address. It seems $DE00 or $DF00 or anywhere in the $D420-$D7FF range may be used, which is rather annoying if you want to play the tune on the real thing.
I think 2SID competitions would be a good thing, but how about only accepting entries which allow the listener to select the address of their second SID? |

Someone maybe could write a simple SID player on the c64 which would allow the user to select the address, and then write the new address values to the correct memory locations of the actual music player loaded. One of the downfalls would be what player was used by the composer, so the code may need to act the same as SIDID, detecting what player is used (i.e. GoatTracker Stereo, JCH player...) and gather the correct memory locations to write to so that it doesn't mess the player up. This would be quite difficult for normal SIDs due to lots of different players been coded over the years, but for 2SIDs it might be easier. And of course, not everyone has double SID expansion on their real machine (I don't anyway) but probably most people listen to them on emulator as most entries are nowadays downloaded. |

well.. making a buffered player on C64 which switches IO space to RAM , then copies sid-register writes somewhere else , turns IO on again and re-writes them to SIDs where they shold actually go isn't that difficult :)
anyway nowadays most ppl tend to use d420 (internal 2SID) and it's quite logical when you consider it's just another sid after that built-in.
on-cartridge SID expansion use DE00/DF00 which is not smart but simplier to build eventually :)

@Raf:
I was actually on about modifying the memory locations in the actual player (e.g. STA $D4EB ($d500) becomes STA $D40B ($d420) via coding in the lo and hi-byte address numbers in memory) which can be set-up outside play-time, but I understand what you mean :-)
Doing what you explained can be done whilst playing the actual music in run-time and that if you don't want to the player to be actually modified. |

Hmmmm, what category should these 2Sid entries be under? Should we just put them under as "C64 Music" or should we get Perff to add a new category? |
