I guess this is not so much a patching question as more wondering if anyone has made a functional (and ok sounding) 3 band EQ with the filters in Usine?
I am making a mixing console for Usiners and I would like to include basic eq without needing to use any vst's but on first glance it seems like the included filter modules are very one purpose and possibly crippled by the fact that their gain control affects total gain of the audio output, not just boost or cut within the specified frequency range..or is it possible I have found a glitch?
Also it would be very handy to be able to see the cut and boost for multiple bands on one line instead of having try and interpret the overlapping lines when sending in a bitmap from one filter to another.
Suggestions besides using any one of the million free EQ vst's?
3 band EQ
maybe first fake one filter (ie lp), then using a-b subract this from otiginal input sound so you have a two band, lp, hp., then add a third fliter HP (out from prvious hp - new hp) so yo get 3bands, then dealing with Q and volumes should do the job, meaning for a "basic" 3bands. could then route bitmap out of hp to bitmap in of mf that goes again to bitmap in of lp to see all 3 bands and by the way overlapping on 1 item only.

Hi guru,
not exactly what you need, but could be a good starting point

It's a little 2 band EQ/filter
the interesting part is on bitmap 'compositing' and scale adaptation of the XY pad.
Hope it help

Thanks, but I do not understand... :/
Ok, lets say I am fine with no visual overview of the curves,I can do three filters and have a 3 band EQ, but how do I control just the gain within the frequency Q range? I don't think this is what you are getting at, but are you suggesting somehow using phase cancellation to control the selected frequency gain...?
edit:
just saw your post martignasse, I will take a look.

yup i was speaking of phase cancelation, but scuse me i said nonsense, just tested for me the simpler way is:
take some audio in, route to audio out, ok we got our fullrange sound out.
take a BP filter, that pick audio in, and on out, drive to A of a AxB, on B put a fader going from -1 to 1, drive out of AxB to audio out also,
this make a parametric Eq, you can then choose freqency on filter and Q, and if fader goes to -1 you removes freq, if +1 that boost, if 0 original sound with all in between values.
you can then make any band you want duplicating the bandfilter and choosing adapted frequencies simple and modular Eq,
this let you ie smooth boost a bass at 100hz while removing some with high peak filter at 120, that is not possible with the "crossover" technique i was speaking about.
btween martignasse patch seems interesting i will have a look also.

Do you mean something like this?
I dunno, still doesn't seem right... I could probably spend the next month studying EQ theory and figuring out how to build the perfect EQ in Usine but this is really not how I want to spend my time...I think I will leave my EQ slot empty for now.

mmm yup i was speaking about this, (if all filters gain set to 0db, and B fader going from -1to1) what's wrong with it?
here it seems working not that bad, i can clearly hear some bass boost/reduction, same for mid and hi, and mathematically it does some. just cannot make extreme add/reduction, but as we were speaking about a "basic" 3band? Note if need good real Eq i think a dedicaced VST is better for that, usine isn't really a dsp or synth even if it can do some nice things, that's not it's primary concept, and imo any "wired" attempt will probably results in higher cpu if ever reaching equivalent quality than some vst that have really been made and optimized/encapsuled for a specific and only one task.

I guess nothings wrong with it? I definately do not understand the theory behind how a EQ "should" work, so maybe it's just that it seems unintuitive / finicky to use. I have definately learned something new so that is good and perhaps the lightbulb above my head will go off and I'll get inspired to tinker with these EQ ideas some more.
I have hit a wall with what I was trying to make anyways so instead of getting more frustrated I am going to toss it in my junk pile for the moment and work on finalizing my own personal workspace so I can maybe make some music.
Someday hopefully I will actually finish a nice addon to share. I have lots of good ideas but I always hit a wall when trying to make my ideas actually work how I want them to...
