MFH Mod (FoFiX) 3.0xx (v3.030) (OLD)

Nice progress on the whammy pitchbend, JS - I just tried it and it's getting much better.

We need to make the pitchbending a bit smoother though; are you currently using two out-of-phase sample buffers with a crossfading function to allow seamless stepping through the samples at any rate? It sounds like just a single buffer. I'm going to take a look at your pitchbend module's CPP source and see if I can come up with some changes to try, although i'll need you to build it into an installable module for me :)

Something tells me this isn't going to be easily converted to Mac/Linux.

if i set the game to show the fps, and i change the framerate value in the video settings should the reported framerate be capped at whatever i set this to, assuming the pc is fast enough

as setting this seems to have no effect 15 or 115 it still gives the same result

make sure "highpriority" is set to "False" in your fretsonfire.ini - if not, it will just render as many frames as it can as fast as it can.


Also, below is an 8-bit mono pitch-shifting algorithm that makes use of cross-fading two out-of-phase sample buffers for seamless pitch-shifting / pitch-bending. Written in C for a microprocessor:

Code: Select all

DelayBuffer1 and DelayBuffer2 are the two out-of-phase buffers that are stepped through at a variable rate
DelayBuffer6 holds the crossfading triangle wave
PitchOffset is the rate it steps through the buffers.  A 256 = no pitch change.  <256 = lower pitch, >256 = higher pitch
The PitchShiftAlgy macro code is run every time there is a new sample to process.

This code just fills the triangle wave buffer, for crossfading:
#define InitializePitchShiftArrays j=0;    while (j<129) \
        { \
            DelayBuffer6[j]=j; \
            j++; \
        } \
        k=127; \
        while(j!=0) \
        { \
            DelayBuffer6[j]=k; \
            j++; \
            k--; \
        }


#define mPitchShiftAlgy
        DelSig_bfStatus=0; \
        k=k-3; \
        DelayBuffer1[UCindex]=k; \
        DelayBuffer2[UCindex1]=k; \
        temp = UIskip>>8; \
        UCout1 = DelayBuffer1[temp]; \
        UCdelta=temp-UCindex; \
        UCgain1=DelayBuffer6[UCdelta]; \
        UCout2=DelayBuffer2[temp]; \
        UCdelta=temp-UCindex1; \
        UCgain2=DelayBuffer6[UCdelta]; \
        UItemp1=UCout1*UCgain1; \
        UItemp2=UCout2*UCgain2; \
        UItemp3=UItemp1+UItemp2; \
        pwm_out=UItemp3>>7; \
        PRS_Reverb_SEED_REG=pwm_out; \    (this is the output sample)
        UIskip += PitchOffset; \
        UCindex++; \
        UCindex1++;

the highpriority setting fixes the turbo animation / broken meter problem so thats great
i guess anyone with a new ati card will need to set this

The icons implementation wouldn't really bother me, seeing as I already have all my songs divided into folders according to the game

What makes you say that? I could have sworn he had posted the source somewhere, I just haven't tried it myself.

It's in SVN (svn co https://svn.stump.jstump.com/svnroot/pitchbend/trunk) and is under GPLv2 or later. Use the link in my signature to browse my code.

I have successfully built and tested it on both GNU/Linux and Windows.

I stand corrected.

The beta 2 is great.
how about release it?
what are the main bugs that are stopping the RB2 Setlist from coming out?

[qb8young]

I have posted my updated Guitar Hero icons here: viewtopic.php?p=333254#p333254

[mario-182]

What are the main issues being targeted at the moment for the next release?

[blazingamer]

Apparently pitch altering whammy and the ability to slow down the board speed in practice mode.

You can squeeze a note to the right of a note is being played

You've always been able to do that...
