HI, I looking echo & reverb effect (stereo ,like from creative effects) for kx drive 3535, but default echo from kx is sux... help me....

Hi, again....

I looking that site,... and find echo source.... and I remake and added two slider for delay size.... but this is not work then I can... I move slide del1 to 6 value and delay is full size... when I move to last slide position and other position is work something wrong.... help me....

Code:

acc3 &d1r, del1, &d1, 0x0;
acc3 &d2r, del2, &d2, 0x0;

no.
Range of sliders for control registers are always 0...1 (or 0...0x7fffffff in hex) for raw *.da plugins...
So if you add value of del1 to the base address of delay you are just jumping out of delay time allocated for your plugin (and even out of all of delay memory available for dsp) ...

You should do like that instead:

Code:

...
xdelay write d1 at 0x0; !
xdelay read d1r at 0x4000
xdelay write d2 at 0x4001
xdelay read d2r at 0x8001

xtramsize 0x8001

const maxdelaysize = 0x4000

macs &d1r, &d1, maxdelaysize, del1
macs &d2r, &d2, maxdelaysize, del2
....

where maxdelaysize is maximum time for each delay line...
You may use any other values but following equation should be held:
maxdelaysize == (xtramsize - d2) == (d2 - d1 - 1)
(assuming the size of left and right delays is equal)

HI, MAX M.

Thanx for answer, and I try to use your sugestion... Big thanx..... bye..

filipgolarz · Nov 1, 2003, 12:55 PM

HI again.... MaxM I used your example and not have work...??? I dont know what is that.... voise signal is metalized and dont have echo effect.... ok... bye

Max M. · Nov 2, 2003, 01:26 AM

put here the full source you've tried... (so i could check where was your mistake and please, use original text - not output from disassembler (e.g. 'dump') which is hard to read)

Max M. · Nov 5, 2003, 07:07 PM

And finally...
It was my mistake (doh, how stupid i am - i really need a holiday somewhere in the sun :)

Quote:

You may use any other values but following equation should be held:
maxdelaysize == (xtramsize - d2) == (d2 - d1 - 1)

Should be read as :
"maxdelaysize == (xtramsize - d2) * 0x800 == (d2 - d1 - 1) * 0x800"

---
in above code maxdelaysize should be 0x2000000...

---
Btw. you can find the final code for "delay2003" which includes all of prev. improvemnts, corrections and fixes here:
