for the correct power references (p1, p2 & so on) you need to know which power is associated with which the p-number sounds that it makes. You can do this by checking in his powerstyle file, which can be decompiled using the xmlbcui software.
For example, you want to change Ckye's xtreme into..lets say, sound of rabbits. XD
So what you do is you decompiled his ps_cyclops.engb file using xmlbcui, then you press 'file>edit' to get the xml of the powerstyle (notepad version). Scroll deep down until you see the power details for his extreme (in this case it's power8) & then search for the lines where it stated there "sound = char/cyclop_m/whatever p is here
In this case, I found two of his sound references for his extreme;
name = sound ;
pitch_range = 100 ;
sound = char/cyclop_m/p9_charge
time = 0.04 ;
loop_type = start ;
name = sound ;
sound = char/cyclop_m/p8_loop
time = 0.03 ;
So whenever he activates his extreme, the sound of p9_charge & p8_loop will play. There are two ways to change these sounds, either you type new reference names according to whatever you've written in your zsm & compile the powerstyle back to engb, or just refer the new sounds using the same power references (I prefer the latter).
Therefore to change Cyke's original xtreme to rabbit sounds, we need to get the new sounds ready first!
With the correct format of PCM 22050 16bit mono(you can get this form by resaving your wav in Windows's accessory recorder),open zsm editor & open cyclop_m.zsm. There are three tabs here, but the most important ones are the files & events tab.
In the files tab, the number of the file 'p9_charge' corresponds the 'p9_charge' name in its events (p9_charge=12:p9_charge.wav), and so does the file 'p8_loop' to its event's 'p8_loop' (p8_loop=19:p8_loop.wav). So for new sounds to replace them just go to the files tab>add file & choose the one that you want to add.Then go to the events tab and press the Ins key (Insert). You will get a 0 number while doing this. Click on the zero, and at the bottom of it where it says 'event' type on the box the name of the sound you want to replace(P9_charge or P8_loop).
So now in your zsm, the rabbit file's will be your p9_charge/p8_loop depending on which one you wanted to replace.
So what to do with the old sounds? You can either delete it, or if you want both sounds to occur at random times, just change the events on the original & new sounds into the parantheses p9_charge, p9_charge...
In the end if you want both sounds to occur it will be;
Event p9_charge= File p9_charge.wav (original sound)
Event p9_charge=File rabbit1.wav (your new sound)
Event p8_loop= File p8_loop.wav (original sound)
Event p8_loop=File rabbit2.wav (your new sound)
Gosh what have I written..@_@ I just hope you would understand what I'm babbling about lol
