Thank you Taifunk so much for the! Great job!

For me EQ is very important.
What should be the position knob dry/wet and Lp/Hp
clipping (cutoff) to 60hz <-->from 10.000hz

You're welcome imstre,
I fixed the patch(the attached file to the previous post)
Set the control on wet so the filter is active (the dry/wet type control is an off / on control, not always necessary)this is just a simple example, not really an eq.
For everything else,eq/compressor etc..maybe runaudio can help more than me

Now I understand

Very thanks comerad

Very like Eight Band EQ

question: cpu resources take eight band EQ more than analog Hp48 EQ ?
how to calculate? Thanks

[quote="AndreasD"]Wow, i didn't know that i'm the approved expert around here

But here we go:
Mulab Multimode filter is a State Variable Filter (something you can google) with a total of 12dB/oct slope. This is for all it's filter types!
If you use the LP, it's 12dB. If you use HP, it's 12 dB, If you use the BP, it's 12dB but 6dB for HP part and 6dB for the LP part.
The Mulab TF Lowpass filter is a 24dB/oct low pass and a low pass only.
The Mulab 1P Lowpass is a 6dB low pass and a low pass only.

In general you can put as many filters in series as you like and the result will be a response where the single filter slopes are added.
Asuming you set the cutoff in all modules of the below at the same value:
Connect a 1P Lowpass to a Multi Mode Filter set as low pass and this to a TF Lowpass, you get 6dB/oct + 12 dB/oct + 24dB/oct = 42dB/oct low pass.

Connect 3 Multi Mode filters set as HP you get 12+12+12=36dB/oct high pass.
Switch one of them to LP and you get a band pass with a 24dB/oct HP and a 12dB/oct LP.

Now those numbers Runaudio provided are settings for so called Butterworth filters. Because of their characteristics they are most often used in crossovers. If, for example, you have a HP and a LP in parallel and add them, you get a flat frequency response, which is what you want in a crossover.

As said, these numbers refer to the Q value in the filters (actually the 1/Q)!
Each number is meant for a 6dB slope. As we only have a 12dB universal filter in Mulab that can adjust Q, we have to combine 2 numbers for 1 Multi Mode filter.
Following the numbers you can directly dial in the Multi Mode filters:
12dB = 1 MM filter: Q=0.71
24dB = 2 MM filter: Q1=1.3, Q2
36dB = 3 MM filter: Q1=1.93, Q2=0.52, Q3=0.71
48dB = 4 MM filter: Q1=2.56, Q2=0.9, Q3=0.6, Q4=0.51

Were is the number for Q2 for 24db

Q2=0.541184
