Making a Key follow EQ with MUX???

[Trancit]

Is there somehow the possibility to setup an keyfollow EQ, where I can make set EQ frequency following incoming Midi data...

Means i.e: I have a bass line playing an E note... I setup the EQ that I boost the root note (i.e. E1=82,4Hz) with a higher Q and lower down the first harmonic (in this example E2= 164,8Hz)...

Now I want this set frequencies to follow, if the bassline goes from this E to a G (would be 98Hz and 196Hz) then to a C and back to the E again ... without having to do it by automation, which is a PITA...

So I need some kind of keytracking, which translates the incoming midi notes to the exact corresponding Hz values...

How???
And if not possible atm... could I have something like this please...

Simply use a Multimode Filter, set it to Peak EQ, route the bass thru it, also connect the MIDI input for that bass to this filter and set key tracking to 100%.

Or am i missing something?

Doesn´t work here (was wondering as well)... the frequency doesn´t move at all here...

What I did and it works sonically but not visually is to map a "Note to modulation" converter to the frequency of the Multimode Filter... this works fine in terms that the frequency matches sonically, but sadly there is no visual feedback in the Multimode filter... a bit cumbersome to work with...

If I map the converter to a VST EQ, I cannot manage to map it correctly... the intervals are not matching...

Thx, exactly like this I did it as well

Works fine here, simple and easy.
Are you sure you have the relevant MIDI in connected to the filter?

Ok, first I must fiddle out how to set it... but I am not sure, if I made it correctly...

I noticed, that Midi note 60 is the root for the key follow... correct??? (yes, I could have looked in the docs before )

If I set i.e. the peak to 65.4Hz (C2) it works as expected and the peak follows the keyboard, but I have to set the frequency to a C (65.4Hz...or 130.8Hz...or 231.6Hz...etc...) value... correct???

Btw: Is there any chance to set up a real PingPong delay in MUX??? EDIT: without using 2 or more Delays...

Ping pong is just the modulation, isn't it? One LFO, square wave, controlling pan, one envelope, simple Attack/Decay shape, controlling LFO depth. "Modular feedback delay", of course, as you can't do it with out feedback, and you can't wire MUX up to have feedback directly.

I am not sure, but I don´t think, using a pan modulation via LFO does the same...
And second... then I can use 2 delays as it wouldn´t cost me any more time to setup...
But nevermind... it isn´t a big deal

About the Follow EQ: To be honnest i don't understand what's difficult about it.
Attached the "Basic Synth" patch with a Peak EQ inserted that follows the played key.
See modular area, i didn't touch the front panel.

The only thing i did was inserting a Multimode Filter in Peak EQ mode, route the synth audio thru it, and also connect the event input to it so it can follow the key. Keytracking is at 100% by default so didn't even have to set that. Of course you can tweak the EQ freq as you want, and it will keep following the key relatively.
Yes the pivot key for key follow is middle C = key nr 60.

About the Ping Pong Echo: If you plugin the "MuEcho" device you have one.
It's also used in many presets eg Basic Synth.

...

And this is the point... it shall not follow relatively...
If I want to precisely boost the root and cut down the 1. harmonic of a sound I need the exact frequencies to be followed and to let the Multi Mode Filter do that you have to set the frequency first correctly before it can follow... and this was my question, if I did it right...

And about the PingPong Delay... you know what happens???

I don´t know, why this happens but I tried it many times and it always did:

left - right- left- left- left-left... so not a ping pong...

Now, after you told me it is... I had another look and my fault was... I always set the smaller value as "Echo Time" and the longer value as "Right Dely Time"... and then it doesn´t work...
This you have to tell silly people like me...

But now, everything is fine and yes, MUX got a nice PingPong Delay!!!

So the question is not how to EQ but the question is what to EQ, right?
Isn't that up to you, as it depends on the sounds you're using? What about using a spectrum analyzer to find the right spot?

I think, you misunderstand me... but I am quite sure I´ve got the correct answer...

The pivot key is 60 ... it´s C3, C4, C5 depending what scheme you use...
To let the frequency follow exactly the corresponding frequencies for the incoming notes, you have to set the initial frequencies to any of the corresponding "C" frequencies...

Only this way the frequency of the i.e. peak filter will jump to an "E" frequency if you press an "E" on the midi keyboard (leaving the octave beside) ...

I just wanted to know, if I am correct thinking that, or do I have some error in mind... that´s all

I still don't understand what you want to do, but i guess that's me.
Because if u want to boost/dim a certain harmonic, that's relative to the key and so with key follow properly set up, that same harmonic will be boosted/dimmed all the time, whatever key u play. So it's just a matter of selecting the right harmonic once. It doesn't matter if that's done using a C or E or A key. Right? I'm sorry if i'm missing something obvious.
Most importantly: Is your question answered now or not?
