Basically it is music originally generated on the C64, a popular family computer from the '80s. The C64 was undoubtedly ahead of its time offering many advanced features for a relatively cheap price. One particular advanced feature on the C64 was the Sound Interface Device (SID) chip developed in 1982 by Bob Yannes. The remarkable capabilities of this chip cause a revolution in the computer music industry. The chip was so revolutionary in fact that Byte Magazine named the chip one of the Top 20 most important chips in computing history (see Byte's 20th Anniversary tribute edition, 1996). Although the design of the chip was quite a feat, the true test of technology is what people can do with it. The early musical pieces on the C64 were impressive for that time frame, but the hidden potential of the chip wasn't heard until 1985. Composers began to use audio "illusions" that tricked the ear into hearing more voices than the three-voice chip actually had. The music continued to progress in 1987 when musicians began to utilize a fourth voice which was dedicated for samples. Although many other improvements to SID music have been made over the years, none were as important as the two just mentioned. More importantly, though, was the release of this technology to the C64 public world. Back then, composers had to also program their own tools otherwise the composers would have to create their music using primitive software. Due to a competitive game musician market, however, musicians were reluctant to share their knowledge. Through reverse-engineering and some eventual leaks, the C64 public soon utilized some of these advanced music tools creating a boom in the amount of quality music available. Throughout the 1990s, the C64 game industry may have ceased to a halt, but there are still many musicians who compose for demo groups, who still enjoy the challenge of squeezing as much as they can out of the SID chip. Most of these new tunes will hold special memories for people, but in a different way in that you'll remember them from demo X or Y rather than as a game soundtrack. [1-2] The HVSC Project ====================== The HVSC Project is an attempt to accurately archive the most popular C64 SIDs into one complete collection. The project was started in May of 1996 when a few ambitious people decided to merge the many SIDs collections available on the Internet into one masterpiece. The previous SID collections contained many bugged SIDs, repeats, and inaccurate credits not to mention being highly disorganised. Thus this task was not a simple "copy & paste" unfortunately. An additional challenge for us dealt with being compatible with other platforms. The only way one true collection can exist is if we remain compatible with the major operating systems currently in use. As we merged the collections we began to realize that many famous SIDs were missing. This led to the HVSC crew and many others to begin searching various C64 software archives for more SIDs to rip. Due to this effort the collection began to grow at an enormous rate. As we progressed, we then noticed that many inconsistencies and questions started to surface. For example, we would find a music credited to a famous composer yet the style of the music was completely different than his normal style. One sure way of solving these mysteries was to contact the original composers. Over time we gradually tracked several of them down and received a tremendous amount of information. As you may have figured out, we are SID archeologists patiently piecing together SID history with only fragments of information. You may be asking yourself, "Why go through so much effort for SID music?" Only a person who never owned a C64 would ask such a question. Many people long to hear these old, classic tunes that they enjoyed in their youth. You don't believe us? Look at the amount of Television sites that recall many a program that as a child you treasured and how much memories you get from that. With SID music, this is true equally if not more so. Thankfully with the abundance of SID emulators this is now possible. What was thought to be lost is now found. Let the tears of joy proceed as you listen to perhaps the most accurate and comprehensive computer music collection in existence. * SID emulators are available for many operating systems such as Linux, MacOS, BeOS, Atari Falcon, Windows (3.1, 95, 98, NT), MSDOS, AmigaOS, OS/2, etc. For a complete list of supported OSs with links see: The InSID Asylum - http://www.dhp.com/~shark/c64music/ [1-3] The HVSC Philosophy ========================= The HVSC is a free-ware collection. As tradition with most free-ware projects, the organisers maintain the project in their free time. In order to help the HVSC crew keep their sanity, we expect everyone helping the project to avoid burdening the maintainers with mundane tasks. What exactly do we mean by this? Well, basically we expect that if anyone emails us with comments, SIDs, questions, etc., that they have first put forth some effort so that we do not have to ourselves. It is all very well stating that certain tunes were composed by a certain composer, but if you can also submit any worthwhile information to support your statement, then we can check this for ourselves as well. One must realise that a tremendous and painstaking amount of man-hours have gone into the project. In order for the collection to continue on, we cannot continue to put forth as much time. Thus, we ask that you take on some of the burden. Don't let that word "burden" scare you too much -- we are only talking about a small amount of work here. Here are some general, friendly rules to keep in mind: * Every SID you submit _must_ follow the HVSC credit standard (see Section 3-2). * Verify claims you make about a SID being bugged either by loading the original tune on a C64 or on a C64 emulator. Also, if tunes are missing from a SID, then please let us know which ones (see the BUGLIST.txt file for more information.) * Verify any credit changes you submit either with the composer himself or by loading the actual software. In general, the messages are VERIFY and STANDARDISE. Unfortunately, if you do not follow these simple rules we will either ignore the email or you will experience a long delay until the submitted changes take place. We hope that we are not coming across as rude, but as we have already noted, we have spent years on this collection verifying its correctness. Further, we have spent many a day correcting and re-correcting the credits of SIDs so that we can also serve as a vault of information of SID music. If people do not work with the same level of precision as we would like them to do the collection will take a regressive step. --------------------------------- CHAPTER [2]: Collection Structure --------------------------------- There are several ways in which most SID collections have been organised. To name a few, by Author's first name, by categories such as demos and games, or to have a simple rat's nest of SIDs. We have chosen to arrange the collection by the author's last name or by the author's alias if it was used more frequently. In addition, we have a two level hierarchy scheme where the more famous and professional composers are grouped above the demo composers. This no way indicates the quality of composition. Finally, we usually only give composers their own directory when we have five or more tunes available from them. This then makes it a little easier for you to locate the composer. Below are a some comments about a few special directories: /DEMOS - For tunes found in demos in which the artist has less than five tunes. /DEMOS/UNKNOWN - For tunes found in demos in which the artists are unknown. /DOCUMENTS - If you are reading this document, then most likely you have already figured out what this directory is for. It also keeps an archive of all the update data files and information texts. /GAMES/X-X - For games first released in which the artist has less than four tunes. Game tunes with unknown artists go here as well (sadly, many an older C64 game had no composer information and we usually have had to contact the programmers themselves also to verify) /VARIOUS - As mentioned above, this is where mostly demo composers from post-1992 or lesser known composers reside. Below is the algorithm we use to decide where the composer goes. (1) If the artist has no tunes made in 1992 or earlier, go to step #4 (2) If the artist has game tunes (3 must be made in 1992 or earlier) above Various else go to step #3 (3) If the artist was a famous demo composer in 1992 or earlier above Various else go to step #4 (4) Below Various ---------------------------- CHAPTER [3]: How Can I Help? ---------------------------- [3-1]: Contributing SIDs ======================== We love to receive new SIDs for the HV SID Collection. Of specific interest are tunes from games, mainly because the game tunes bring back more memories for the people that played them and they were commercially available, but we'll take anything you have unless the tunes are lacking musical skill (subjective). Here are some other items we are looking for: * Complete collections directly from the composers (this is most ideal as they will usually have all the information we require, too) * Loading/Intro tunes used in games. These are rare since crackers would often not include the tunes along with the cracks. In particular, cassette loading themes would often not make it in a crack. * SIDs already in the HV SID Collection, but with additional sub-tunes. SIDs with additional sound effects are okay, but we prefer SIDs with more tunes instead. The reasoning behind this is that the extra tunes would have memories from the game for people (particularly any game complete tunes). * Fixes of SIDs already in the HV SID Collection. We have found several tunes that start at the wrong location, have missing voices, with bad samples, etc. Do if at all possible check them on a C64 first. - We DON'T want any Compute Gazette SID tunes *unless* you find a few that are exceptionally good. We have already listened to NemeSIDs #18-#19 and have rejected around 99% of those. The only Compute tunes generally allowed in HVSC are those which featured in games. - You will notice groups of tunes where there will be a gap in order. These gaps usually do not mean that we are missing these tunes, but rather we have found them repeated elsewhere. - We also DO NOT want any SID collections from the Internet unless you are pretty certain none of the tunes are in HVSC. HVSC will most likely already have all these SIDs. If you send us collections from the Internet we expect you to eliminate the tunes we already have and make the credits adhere to the HVSC credit standard. - Further, we DO NOT want any C64 tune that is just one looped sample playing over and over again. Unfortunately around 1987-88 there were a spate of sample-only tunes that had one 20 second long sample either playing once or infinitely. If in any doubt, ask us first. If you have SIDs and would like to send them to us, there are several methods in which this can be achieved. We prefer them to be emailed as an included attachment (preferred) or to be uuencoded. There are other possibilities so feel free to email us and we can arrange what ever is most convenient. Note, do not forget to adhere to the HVSC credit standard (see below for more information). Please also DO NOT send any attachment that is more than 500KB without mailing us first to let us know and that you have confirmation from us it is okay to send. Unfortunately, a lot of phone companies' pricing structures mean that we have to prioritise our time on line to this effect. Please mail them to _both_ of the people below: Warren Pilkington Jan Diabelez Arnt Harries (Rambones/TST) You can also if you wish snail mail the SIDs to us on 3.5" disk. Contact us and we are sure we can arrange something for you. [3-2]: SID Credits ================== For those of you that rip, below is the standard for labelling SIDs. The standard should be strictly followed. If a few rare cases pop up in which you are unsure how to handle, just do the best you can or mail us first to discuss the credits. We can always advise you if need be. SID Credits Standard -------------------- NAME : AUTHOR : <FIRST_NAME LAST_NAME> (<ALIAS>) COPYRIGHT : <FOUR_DIGIT_YEAR> <COMPANY or AUTHOR or GROUP> Fill in any unknown field with a <?>, apart from the COPYRIGHT (see below) Place a maximum of 31 printable characters per field for compatibility reasons. ----------------------------- Examples: <All information is completely known> NAME : Hysteria AUTHOR : Fred Gray COPYRIGHT : 1987 Software Projects <Author and Company are unknown> NAME : Night Racer AUTHOR : <?> COPYRIGHT : 1988 <?> <Author is thought to be known with a *strong* degree of certainty> NAME : Cheapskate AUTHOR : David Whittaker <?> COPYRIGHT : 1989 Firebird <COPYRIGHT date is not exactly known and crack intro has a date or> <you know an approximate copyright date. Dates in crack intro, by> <the way, can often be extremely inaccurate compared to the actual> <copyright date of the game. > NAME : Deep Strike AUTHOR : Rob Hubbard COPYRIGHT : 198? Durrell Here is a list of how the COPYRIGHT year is handled for various cases: 198? - tune is made in the '80s 199? - tune is made in the '90s 1988-89 - exact year in which tune was made is not known, but it is known that the tune was made in this range. 19?? - tune was made in the 20th century. :) ------------------- SID Credit Pointers ------------------- (1) Rippers: ABSOLUTELY DO NOT PUT YOUR NAME/ALIAS IN THE SID CREDITS! (2) You should be at least 80% certain of the field you are guessing. To put incorrect credits rather than a <?> would forever ruin your reputation as a serious SID collector. :) When in doubt, at least follow the doubtful information with a <?>. (3) Just because a tune uses another author's famous music routine, that is not enough to signify with certainty that the tune is by that author. Sometimes authors lent their routine for another to use. Other times the routine was used without permission. Again, please use <?> if not certain. (4) Don't make up titles (e.g., TITLE: This Tune ROCKS!). If you are ripping the tune from a demo in which the music was specifically made for that demo, then you can use the demo's name as the title, provided the composer did not give the tune a name. Often the first few characters of the tune reveal the name, so please do check when ripping. (5) DO NOT PUT A SPACE AFTER THE '=' CHARACTER IN THE SID HEADER! (A space should not be the first character of any credit field) (6) Try to follow standard English capitalisation rules when inserting the titles into the SID fields. Examples: The Way of the Exploding Fist {correct} The Way Of The Exploding Fist {incorrect} Note that if the composer intends some of words in the title to be in lower case, then comply with the composer's wishes (but let us know). (7) Normally, you should make the default tune of the SID the first tune you would first hear when running the game/demo. This is either the cassette or disk loading theme (if there is one) or the title tune of the game, or the first tune of a demo. (8) We prefer to have the musician's real name in the AUTHOR field. If possible, we like to have both alias and real name for demo tunes. The author's real name should precede his handle. Standard -> <AUTHOR's REAL NAME> (HANDLE) Examples: Torben Hansen (Metal) {correct} Torben "Metal" Hansen {incorrect} At minimum, the name that the composer used in the game/demo should be in the credits. Only if there is enough room should you put the his real name or alias. Note also that you should not put the composer's group name in the AUTHOR field. Either put such info in the COPYRIGHT line or do not add the info at all. (9) At a minimum, make sure to get the C64 publishers in the copyright line for games. If room is available, feel free to add additional information such as the arcade publishers. DO NOT assume that the programming team would have published the game themselves. We do have access to Zzap! 64 reviews indexes, various large collections of original C64 games that we check and double check to make sure. (10) The documentation that is included with SIDPlay includes a large quantity of information about how to get C64 tunes working with SIDPlay. Further, you will find other documents related to the area of SIDs including SID header information at the SIDPlay homepage. SIDPlay homepage - http://www.geocities.com/SiliconValley/Lakes/5147/ [3-3]: Identifying Mistakes =========================== We know that there still exists several mistakes within the HV SID Collection and we would appreciate any help in correcting the mistakes. In addition, we also would like to have missing information in the SID tune credits (i.e., filling in the <?>'s). If you have some corrections or some additional information, no matter how insignificant, let us know. Please mail to _both_ of the people below: Warren Pilkington <wazzaw@globalnet.co.uk> Jan Diabelez Arnt Harries (Rambones/TST) <rambones@get2net.dk> Before you mail us, please verify the information you are sending by either loading the game/demo yourself or contacting the original composer. We have squashed many common beliefs as to who _really_ composed several tunes. You might be surprised to see one of your favorite tunes now with a different author (the correct one we hope). This is why we suggest you first verify the information you plan to send us. Further, we would like to mention that you should not use C64 emulators to compare to the sound of SIDPlay or to identify mistakes with tunes in the HV SID Collection. Ideally, you should play the music on a real C64 and if then you determine that the sound of the rip is not right, you have a valid complaint. There are few instances, however, where a C64 emulator can be used to show that a sid tune in HV SIDs is a bad rip. Such cases would include a tune with missing samples or a tune with missing voices. As yet, most C64 emulators do not emulate the SID filter at all (CCS64, the most popular C64 emulator, C64S, and PC64.) and due to the variance of filters between C64 machines (up to 20%) you may hear a slightly different filter setting in HVSC (this can be adjusted in Sidplay). Please bear this in mind. [3-4] Ripping SID tunes ======================= Much information about ripping is provided at the SIDPlay web site. http://www.geocities.com/SiliconValley/Lakes/5147/ (click the 'Info' link) *Note, ripping SIDs requires some assembly language knowledge. Thus, ripping SIDs is not always an easy task (but it isn't always hard, either). The point we are trying to make is that if you do not plan to rip the SID the correct way, then do not even bother ripping the SID. In particular, do not cut off the end of the music data by 2-3 bytes, as this often means that the SID will fall out of synch either in a portion of the tune, or on restart. ------------------------------- CHAPTER [4]: Update Information ------------------------------- The HV SID Collection will be constantly maintained by providing zipped update files. These updates will add new tunes to your HV SID Collection so that you will always have the most accurate SID collection around. To handle deletions, renaming, moving, etc. of files, we will also provide a 'sweeper' program that upon execution will clean up your collection for you. Isn't automation wonderful? ************************************************************************* * It is therefore _important_ that you keep the HVSC structure and * * filenames as is, otherwise the sweeper will fail to work properly. * ************************************************************************* The updates will be announced at the INC C64 Music web page as well as other locations. There is no set time as to when the updates will be available. The frequency of updates will depend on the amount of new tunes and corrected information we receive. The current rate of updating is every two to three months, but as we now have 9000+ SID files, the likelyhood of finding more does diminish with every update. The InSID Asylum -> http://www.dhp.com/~shark/c64music/ (under the 'High Voltage SIDs' link.) Also, if you wish to be added to the HVSC Update Announcement list, which means you get an email the moment the URL above is updated announcing the new HVSC Update release, then please email Warren Pilkington <wazzaw@globalnet.co.uk> placing 'Add Me To HVSC Update Announcement List' in the subject line. ------------------------------- Chapter [5]: Included Documents ------------------------------- The following lists the documents that reside with HV SIDS (/DOCUMENTS): BUGLIST.TXT - A list of bugged SIDs in HV SIDs. Hopefully you'll see less entries after each update. (We do try and add as many fixes as possible.) HV_SIDS.FAQ - Answers to frequently asked questions about the collection. You should read this before emailing the HVSC creators with questions. MUSICIANS.TXT - A list of most of the musicians who ever composed more than 2-3 SIDs on the C64. We would appreciate any help in fixing errors in this list. Further, we would also like to know artist's real names for the sake of possibly identifying other tunes by these artist. That is, some artist composed tunes under an alias as well as their real name (e.g., Neil Baldwin = Demon). STIL.FAQ - STIL Frequently asked questions and STIL format issues are discussed in this file. Further, a list of STIL HEROes are in this file too. Do you have what it takes to be a STIL HERO? STIL.TXT - A text document listing information about the SIDs in the HV SIDs Collection such as original composer's name, comments from the SID composers, and interesting trivia. UPDATExx.HVS - A list of fixes and additions that are performed to each update. If you want to know exactly why certain SIDs were replaced, this file will likely have the answer. The xx in the file name will increase sequentially as new updates are released. ---------------------------- Chapter [6]: Acknowledgments ---------------------------- Thanks go out to these musicians for their help: ================================================ Adam Gilmore (thanks for all the tune credit information) Allister Brimble (lots of handy credit information on your tunes) André Schröder (Andre/Oxyron) (for your tunes and then some!)
