| Question on music engine |

Is there anyway to create a special "music system" for Allegro games? Let's see if I can explain this... ------> SIG TIME! "You know, I could be working on that battle engine... But NOOOO~, I'm too busy tweaking the title page." -Me |

You haven't lost me. That would be a pretty good system... I was thinking about suggesting it before... I think. Maybe the creators of DUMB will add that to the DUH music file specification? |

You could probably make this fairly easily using some basic waveforms (square, sine, triangle, sawtooth, and noise), a simple engine to play multiple looping samples at various frequencies, and using a few simple effects (like ADSR envelopes). Use some simple form of scripting for the music sequencer... say, a list tracks to be played, each with a sequence of notes with duration, and the odd effect inserted here and there. Poof! Oldschool chiptunes in a can (or something)! ---- |

MIDI does that, sort of. -- |

ohh. this reminds me of an entry from the first SpeedHack. It used a fairly complex 'language' to describe the various 'parts' (instruments) and the actual tune. Its very impressive. I'll try and find a link [edit]Can't seem to find it... But it was very nice -- |

The problem with MIDI is that it doesn't use the same sound bank. Each sound card has it's own, so what sounds good on one care may sound horrible on another. And nothing sounds good on junky sound cards. ------> SIG TIME! "You know, I could be working on that battle engine... But NOOOO~, I'm too busy tweaking the title page." -Me |

I'll try and find a link That wouldn't be SPEED, would it? If there's another entry from the first SpeedHack that does anything like that, I'd like to know! Failing that, there's Cupid which uses some OO stuff to synthesise the sound effects on start-up, or TeleHack which uses DUMB's undocumented architecture to synthesise music (and unwisely sound effects too) in real time, but these aren't from the first SpeedHack... If you're wondering about DUMB's undocumented stuff - it'll be finalised and documented for DUMB v1.0, but I make no guarantees as to when that'll be -- |

no.. Shawn hard coded all his stuff. The one Im talking about was only a synth (no game), and loaded a text file with a phunky syntax that detailed the tune, tempo, etc... -- |

I don't know if it was in the first speedhack, but this sounds a lot like Christian Schueler's Virtual Synthesizer... This is quite an impressive piece of code, and the songs actually sound very good. They are however quite indecipherable |

That's why I said "sort of". -- |

YES!!! That is it I think It was originally released arround the first SpeedHack (I could have swore that was what he ended up dooing for the first speedhack, but never sent it in...) -- |

Oh, In case anyone had troubles compiling "Christian's virtual synthesizer" with Mingw32, you need to do a few things... add #define M_LN2 0.69314718055994530942 to synth.h and change a few of the C++ includes into real C++ includes... chage: #include <istream.h> #include <strstream.h> #include <string.h> to: #include <iostream> #include <strstream> #include <string>
Then It sould compile... Now before anyone asks WHY Id want to recompile it... It sounded like crap using XP's emulated SBPro in emulated DOS.. It sounds a bit better using the actual sound hardware -- |

im trying to compile christians virtual synthesize for linux. i had to change a few things in the source, but now im getting the error that allegro redefines what fixed is. in iomanip, fixed is an std function in the form of |

Im not sure... Hopefully someone else can comealong and help In case you want to hear a sample of what it does... I ogg'ed the space01.txt file... [edit]If allegro doesn't provide a #define to change the name... try #defining fixed to allegro_fixed BEFORE you include allegro?[/edit] [edit2]w0w.. While trying to post the last edit.. The whole allegro.cc site was giving 500 errors[/edit2] -- |

As a nasty hack you could try this (untested): Quote:

Apparently the answer to my question is "no." ------> SIG TIME! "You know, I could be working on that battle engine... But NOOOO~, I'm too busy tweaking the title page." -Me |

Michael: put all your tunes into a single MOD file, so they can share samples. DUMB v0.9.1 will contain the necessary API for you to choose which order to start on In the distant future, the DUH file format will provide exactly what you want - but for now that's vapourware. -- |

So, basically I just pack everything into one MOD file, then use DUMB to select where in the file to start playing? Hmm... Sounds simple enough... Only problem will be getting the repeats to work right, but that shouldn't be too hard. ------> SIG TIME! "You know, I could be working on that battle engine...

You could use the "Jump to order" command (Bxx in Scream and Impulse Tracker) to setup several songs inside one file but as I just discovered today, DUMB doesn't support this (very basic and commonly used) command -- |

Actually, DUMB does support it. The S3M loader is buggy in that it doesn't convert the BCD value to binary (i.e. B12 is interpreted as 'jump to order 18' instead of 'jump to order 12' as it should be for S3M files); but this is fixed in CVS. (Go here to set up CVS, and here for instructions on getting DUMB's CVS version.) In the meantime, you could save your music as IT files. Please, if you have any mods that DUMB plays incorrectly, send them to me so I can fix any bugs! -- |
