Labels:text | screenshot | font OCR: AM/FM PROTRACKER/OCTAMED STUDIO; PART 4! THIS ISSUE'S LESSON: VOLUME FINE-SLIDE (or, as I prefer to call it – fine-fading) PROTRACKER: (EAX and EBx) OCTAMED: (1Ax and 1Bx) NOTE: THERE IS AN EXAMPLE PROTRACKER MODULE THAT GOES WITH THIS ARTICLE!! THE MODULE IS STORED IN THE "Music" DIRECTORY ON THIS DISK, AND IT'S CALLED "MOD.FINEFADE-EXAMPLE". IT CAN BE LOADED INTO BOTH PROTRACKER AND OCTAMED! ****** Ok, listen up: Since we also want to support OctaMED just as much as Protracker here in AM/FM; and since OctaMED also has all the functions of Protracker (and more!), this tutorial series will from now only be written for BOTH Protracker AND OctaMED!! The commands themselves are often identical in these two programs, even though they use different "codes" to trigger. For example; this lesson will deal with the "Volume Fine-slide" function, which is triggered by "EAx" and "EBx" in Protracker - and "1Ax" and "1Bx" in OctaMED, but otherwise the function is identical in the two programmes! The "Volume Fine-Slide" functions in Protracker/OctaMED are used by putting EAX or EBx in the command-digits of a step. EAx will fade the volume UP, and EBx will fade it DOWN. (OctaMED: 1Ax and 1Bx) have never been These functions much used by many Protracker/OctaMED-musicians. But they can be extremely useful, and make things easier, as well as making your music more polished. The good old "A" command has been used a whole lot though, and to be able to understand the EAx/EBx functions, you first need to understand the "A" function. ("D"-function in OctaMED!) C-3 01A10 (Protracker) C-3 01D10 (OctaMED) Take a look at the above step. A C-3 will be played with instrument 1, and it's volume will fade up ONE unit PER V-BLANK. If the tempo is set to 05, well then the volume will fade 5 up, say, from 30 to 35. (If the instrument's default volume was 30) C-3 01EA1 (Protracker) C-3 011A1 (OctaMED) In this example though, the "Fine-slide" function has been used with a value of 1. In this example, a C-3 will be played with instrument 1, and it's volume will fade up ONLY ONE unit, no matter how many v-blanks this step lasts! *Only* on the very first VBlank, will the volume be changed. So you see, where the old "A" command was depending on the tempo of the song, the EAx/EBx isn't - and will only fade down as many units as you ask for. Take these examples: (Let's say the tempo is 06) C-3 01000 C-3 01000 --- 00A01 --- 00EB2 --00A01 00EB2 00A01 00EB2 00A01 00EB2 00EB2 00A01 00EB2 00EB2 00A01 00EB2 00A01 00EB2 00A01 00A01 00EB2 00EB2 (OctaMED replace EB2 with 1B2) In the example on the left, the "good old" A-command is used. The volume of this sound will fade down ONE unit PER V-BLANK, which means, since the tempo is 06, that it will fade down 6 units per step! In the example of the right though, the EB1-command will ignore the tempo, and just fade down TWO units for each step. This will give a much slower fading than the example on the right. Another useful area for this function: If you're one of those who always changes your volume by using absolute values, like this: C-3 01C01 00C02 00C03 00C04 00C05 Co 00C06 00002 00C07 Ада 00C08 00000 00C09 АДА ООСОА ХАДАН ООСОВ 00000 ООСОС OOCOD OOCOE OOCOF 00C10 ...remember that this can be replaced with: C-3 01C01 00EA1 00EA1 00EA1 00EA1 OVENI 00EA1 OVENI 00EA1 00EA1 00EA1 00EA1 00EA1 OVCHI 00EA1 00EA1 00EA1 00EA1 (OctaMED replace EA1 with 1A1) ...which will also end up on the same volume. The advantages of using this method instead are quite obvious: For one, you can just write in the EA1 command *once* and copy it to all the other steps - this is much quicker than typing in all those absolute values for the volume. Also; if you decide to change the starting volume, you don't have to go through the boring job of changing all the other values - because it will still fade up one unit per step, no matter what the initial volume was.
