White background and black waves?

Damn I didn't know that I've disabled pixel shader, this was the problem...Sorry!!
Now everything is going well.
Thank you!!

probably because of limited right access of windows10 / program files.
Move your full winamp folder to another drive (like D: or E and it should works.
or you could try to start winamp with a right click > start as administrator.

When I try upgrading presets pixel shader version, milkdrop says "This preset already uses the highest pixel shader version (0) supported by your graphics chip."
So I add below code manually
comp_1=`shader_body
comp_2=`{
comp_3=` ret = 1-lum(ret);
comp_4=`}
Nothing happen...

By the way, I cannot overwrite presets and delete presets from the menu.

Delete a preset : DEL -> [y/N] -> y -> a preset isn't deleted -> DEL -> loop...
Save preset : S -> [Save as:] -> Enter -> Overwrite? [y/N] -> y -> [Save as:] -> !?!?

...Why ??

Tested with some presets, result was...

(1) Press M to edit the preset. Don't forget to activate the scrolllock key to prevent milkdrop from changing presets while you edit.

(2) If the preset has a comp shader section, got to the bottom of the code section, just before the closing "}" and insert a line

ret = lum(ret);
or similar, e.g. use ret = 1-lum(ret) to invert.

(3) if the preset has no comp shader section, select "upgrade presets pixel shader version" and confirm. If you get a compiler error such as "undeclared identifier 'sampler__main', go to the warp section and fix it by changing sampler__main to sampler_main.

Now continue with step 2.

(4) leave the edit menu and press s to save.

There are lots of presets with waves colored badly, too much psychedelic.
They are trying to kill my eyes!!!
So I want to edit them and make them look like ink on a piece of paper.

But, too many parameters to edit and I don't know what parameters I should edit.
At least I want to know how to change background color.

Here is a good example as a result I wish.


Any ideas? Thanks.
