  6.   This document is intended for the experienced programmer with knowledge of
  7. a good deal of assembly and the 386. 
  8.  
  9.   This is the documentation for the MASTER TRACKER 2.x AKMTRK1.OBJ sound
  10. routine. 
  11. I realise that several ADLIB players exist on the PC but the editors was never
  12. present with the routines for using in demos.
  13. And i think the Sound Blaster is not a good device to play several digitized
  14. voices when you have a slow PC because this system use a lot of time of the
  15. CPU.
  16. The FM music is quite fast when you use only 4 voices with an ADLIB or SB.
  17. With the new fast registers of the SBPRO/SB16 and GUS, you can use 9 voices
  18. without spend a lot of CPU time!
  19. I think a demo is more good when you use FM music. I think the only GUS demos 
  20. are not fantastic without song when you haven't a GUS (arrrg, I haven't got 
  21. a GUS) and a simple FM music is welcommed!
  22.  
  23.   This code and the .OBJ file were writen by [PYRO-FYRE] from ARKHAM.
  24. If you want to use this thing as it is though, you will have to code in 100% 
  25. ASM. But it could be adapted on other language easilly: my editor 
  26. MASTERTRACKER use these routines with a simple BASIC language.
  27.  
  28. This program don't support the mtr files larger than 64 Kb because of the 
  29. segmentation in real mode.
  30. In fact, MASTERTRACKER 2.x use the REAL FLAT MODE for making music larger 
  31. than 64 Kb.
  32.  
  33. The old music files formats .MTR (v1.x) consist of:

  150. Now you can use easilly this new ADLIB player in your demos and create 
  151. yourself your music.
  152.  
  153. Attention: if you encounter some synchro problem when you do some animation,
  154. you can increment or decrement the value of the 'PUBLIC SPEED:WORD' because
  155. the interruption is generaly called 70 times per second as your monitor in
  156. several screens modes!
  157.  
  158. See you for new quality production from ARKHAM!
