Mega-Demo: A demo that is very large, with many parts.
Intro: A demo that is small, usually no larger than 64K. Intros usually have no more than 5 effects in them, and are usually used to introduce something new, like a demo competition, a new group, or a BBS.
Texttro: Am intro that is quite small, with lots of text and few effects; usually made for small announcements.
Dentro: An intro whose sole purpose is to offer a preview of an upcoming demo that's not yet finished.
Wedtro: An intro whose sole purpose is to announce the wedding of a demo scene member. (Only one to date is Trixter's WedTro)
Babytro: An intro whose sole purpose is to announce the birth of a demoscene member's child. (Only one to date is Nostalgia's BabyTro)
Graphician: (Also called a graphcs artist) Someone who draws the graphics for a demo. Usually responsible for coming up with a logo as well, and an ending ANSI screen. Click here for an example of some of the fantastic art created by graphicians.
Musician: Person who writes the music. Music is almost always written in a MOD-like format or a variant of it, and is composed in a tracker.
SysOp: The System Operator of the Group's BBS, if they have one. The SysOp is responsible for making the group's latest productions available.
Courier: (Also called a "spreader") A Courier copies (or "spreads") the demo around to other people and other BBS's, so that many people can view the demo. Couriers are usually freelance, but some belong to a group.
Demo Group: A group of Demo coders, graphicians, and musicians organized under one name. Some of the most popular groups are Future Crew, Triton, and Renaissance. The diskmagazine Imphobia regularly reports on the top groups. so look there for the most current statistics.
Sattlelite Crew: A group of Demo coders, graphicians, and musicians that help to complete another demogroup's production without actually belonging to that demogroup. Usually these people are members from a friend demogroup, or independent people.
Scene Member: Anyone who's contributed something to the demo scene.
Music Groups: Groups of people who compose music. 90% of the music composed is tracked with a tracker; the rest is either MIDI or another music format. Probably the most well-known music group is the KLF.
Demo Compo: A slang term for a Demo Competition.
Demo Party: A Demo Competition with less emphasis on competing and more emphasis on having fun (not to say that competitions don't have fun--they do, but Demo Parties are much smaller.)
Demo Scene: The entire organization of all people, groups, and productions associated with demos.
Scene Member: A member of the demo scene.
MusicDisk: A collection of music from a demo group, or several demo groups. Usually released when the group's musicians produce more music that the entire group produces demos. Music disks are subject to design, just like demos, and usually have graphics or other information with the songs.
Music Pack: A collection of music from a demo group or a lone scenemember that is usually just the music and a player (in other words, no design at all).
Tweaked Video Modes: video modes that are made possible by "tweaking" (reprogramming) the VGA card's registers. Tweaked video modes have a difficult to work with memory structure, but the advantages outweigh that problem. For instance, tweaked video modes offer the following:
Mode Y: A common tweaked video mode. Mode Y has four video pages and a resolution of 320x200.
Examples of *bad* design:
Effects: A graphical effect that is usually cool to watch. Some older common effects were plasmas, dissolves and fades, and sinuses; many common effects are texture mapping, Gouraud and Phong shading, and motion blur. Many effects can be combined, like a bitmap that both rotates and zooms in and out at the same time. Effects are almost always calculated realtime.
Mixing: A technique to overcome the limitations of PC sound hardware. Normally, PC sound cards can output one or two channels of digitized sound, which isn't very useful if you want to play music with 8 or more channels. Mixing overcomes this limitation by utilizing the power of the computer to mathematically mix all of the channels into only one or two channels inside of the computer. The resulting channel or channels is then output through the sound card. (The number of channels in the output depends on whether the sound card is mono or stereo.) The quality of the output is usually excellent, but can depend on the number of channels being mixed and the speed of the computer. The only drawback to this system is that it steals time away from the CPU.
Gravis Ultrasound: (Also called the GUS) A great sound card at a low price, the Gravis Ultrasound can play up to 32 digital channels at the same time, eliminating the need for mixing. This card has become the standard of the demoscene. (In fact, here's a comparison of its wavetable synthesis against a Sound Blaster for your listening pleasure, in both Microsoft .wav format and Sun/NeXT .au format.) There are three varities: The GUS, GUS MAX, and GUS ACE. The MAX is a normal GUS with cdrom and 16-bit recording facilities; the ACE is a GUS without any recording facilities. The GUS ACE is only $99, which makes it a great way to add wavetable to any existing sound card.
STM: Scream Tracker. This music format was created by Psi / Future Crew. Very similar to the MOD format, it also contains up to 4 channels.
669: This music format was created by Tran, formerly of Renaissance. It was the first 5+ channel format on the PC; contains 8 channels.
MTM: MultiTracker. A newer format created by StarScream / Renaissance. Supports up to 32 channels.
S3M: Scream Tracker 3.0. A later modification of the STM format. Supports up to 16 channels; the tracker used to create these modules is possibly the best on the scene.
FAR: Farandole Composer. Offers 16 channels.
XM: FastTracker ][ format. Recently introduced, the XM format stands for eXtended Module and offers 16-bit sampled instruments, as well as instrument envelopes, MIDI keyboard input, and a great interface. Up to 32 channels.
C/C++: A "middle-level" language created by K&R in 1970.
Assembly: A low-level language that more than half of all demos are programmed in. Very tough to learn, but very fast and offers total control of the computer.
