new 3 Band EQ

Tiger M · Jun 11, 2006, 01:51 PM

the plugin is cool, although there is a better biquad implementation, naturally by Max (I hope he doesn't mind I'm posting his code here)

Code:

name "Max's filter"

 	; coefficients (scaled by /2)        
static 	z0, z1, z3 	   		; state registers
input 	in
output 	ou 
static b0=0x1b40d9, b1=0x3681b2, b2=0x1b40d9;
static a1=0x7b4cfa5d, a2=0xc446023e  

macs	0,  0,  z1, b2
macmv	z1, z0, z0, b1

macmv	z0, in, z3, a2     
macmv	z3, ou, ou, a1    

macs	ou, accum, in, b0
acc3	ou, accum, ou, 0     

end

yep, this one is nearely perfect generalized df1 biquad implementation (i believe)
although, personally i always use df2t form (that's why my EQs use less resources)

I should have known that Max would have a crazy optimized version, lol

.
Very nice, do you mind if I use it here? That would definately save some resources.

Thanks Max.

I optimized the plugin microcode a bit. The resource count is now down to 40/40 (as opposed to 52/46) for the stereo version. Other than that the plugin(s) is the same.

The instructions might be able to be optimized a little more, but the main resource concern is with the gpr's, and I *think* that I have that as low as I can get it with this implementation.

BTW: I added the .reg file to unregister this plugin to the download page as well (I had forget to do that previously).

BTW: I do have one other version of the plugin that I did not include in the release, because I was not sure if other people would find it useful. Basically, I find myself using the exact same EQ settings for both front and rear, so I created a version with 4 inputs/outputs, where the same settings are applied to all channels. This saves 16 gpr's (as opposed to loading a seperate 3 Band EQ for front and rear). If anyone thinks that they might find it useful, let me know, and I will add it to the .kxl (again, it will only be useful if you want to apply the same EQ settings to all 4 inputs).

All effects are useful. Can you post it Russ?

Post the mutha...

j/k

(err... that was me expressing kind interest.

eh hmm... )

Yes please.

Btw: Yur mono one is getting put through the trenches as I play with guitar tone with a project Im working on. (interesting effect to take 2 stereo guitar tracks, and route opposing channels through 2 different EQ's - basically *almost* like a balance control, but by freqs. If that made any sense??)

Anyway - just letting ya know your efforts ARE appreciated, no matter how much I get on your nerves about it....

Sometimes I connect an EFX Tubedrive to each channel using different settings, and I get some interesting results that way as well (particulairly with midi).

Yep KX is pretty cool for us guitar players you can do some very cool things..

Russ · Jun 13, 2006, 09:27 PM

I added the 4 channel version (3 Band EQ (x2)) to the plugin. Link(s) in first post of this thread.

Russ · Jul 24, 2006, 05:30 PM

Added 3538k version. Links in first post of this thread.
