Can anyone make a bipolar rational mapper?

[wlangfor@uoguelph.ca]

Hi all, for effects especially for things like synths that have to vary dependent on the amount of gain it would be ideal to have a bi-polar rational mapper.

So, -1 to 1 and that would mean four states from -1 to 0 would have two levels and 0 to 1.

This I believe is the best solution for people making things which affect gain as I feel sometimes extremes need to have varying returns. Such as q ratio. If someone is using a peaking eq filter as if it were a high pass, then dependent on the reduction amount the q could be made quite wide in resonance.

And given the fact that there is some really cheap peaking filters (on the cpu) then they become very viable for synths too.

BTW, there's (a) link to Micahel Benjamin Voigt's and Infuzion's optimized version of MJ's peaking filter. It's incredibly above par; I'll have to upload from My PC. Not sure where to find it, maybe flowstone guru or..?

EDIT: and not ruby, it'd be for real time q-ratio values or similar, and there's a problem with ruby for that purpose.

There was at least module posted in one of the old 'ToolBox' site.

I'll have a look in my stash later tonite.

Hey everyone. I found something.

here it is:

So this seems to do everything that you might need.

I thought it would be interesting to see what I had planned to accomplish with the this bipolar rational mapper in the form of Barak's array blender thing.

Basically, on Band 250; There is a difference so that the knob is not innately bipolar based on the min max. Neither is the linear gain calculation set to range and linear. The reason was so that the gain can be a float (0-1) that can serve to increase or decrease based on the gain of the slider.

This means that I can increase or decrease resonance at will. I thought this was especially intuitive due to the fact that often in the case of mids or highs that sound tweaks. So, that means with this the resonance can be made higher to prevent that altogether.

Here's the new version of LA bands with some of those advancements added (but only for the 250hz band). I felt that others who maybe made synths would like this so that their tiny EQ's could be made with only a slider and based upon gain could achieve more. Ergo, low shelf down all the way means smaller resonance; ultimately acting as a high pass.

It only makes sense. But, however though I had realized there were other things this method could be used for; This was the only one that came to mind atm.



I add too, that in the case of this EQ; I've found it ideal to stagger MV's ASM de-zippers with the regular de-zippers. Just put reg dezip than MV; then regular etc etc. It seems to avoid any clicking sound and uses only half the CPU as all normal de-zippers. Useful.

you cold save tons of cpu if you pack the dezippers together and you could save even more if you use the additional 2 sse which you are not using for the other EQs. You could almost cut the cpu usage in half.

Hmm, pack together? sse.. Hmm. I've done things like that but never put that to words. Could You possibly ellaborate?

OK, and here's a version where the plane flies from right to left:

This is how you do it. the SSE channel 1 and 2 is for left and right and channel 3 and 4 you can use for another left and right. So in the picture you can create filter eqs in series with just 2 instance. you get 50% cpu reduction. Then you can also pack your values and send them to the correct eq
