I want to know how to do a one pole high-pass filter

I want to know how to do a one pole high-pass filter

When you insert an new object, you are presented with several

categories on the left side of the box that pops up and objects on the

right. There is a category "MSP Filters" that will get you started.

I've see the MSP Filters but there is not a one pole high-pass filter....

Maybe this can work (sorry, not tested) :

You should use filtercoeff in combination with biquad, that will offer you many types of filters.

Also, I don't like the sound of any of the internal max filters and have fallen in love with the 2up.svf~ external, look on maxobjects.com

Onepole is a lowpass filter, but if you subtract its output from the 

original signal you will have a highpass filter.

Onepole is a lowpass filter, but if you subtract its output from the 
original signal you will have a highpass filter.

Really? I thought there was always a few samples' worth of latency in

Really? I thought there was always a few samples' worth of latency in  
any filter.

I know there's a right answer to this, but here are at least some 

Delaying the input by one sample accentuates the highpass effect, but 

shows a boost as the cutoff gets close to half the Nyquist frequency. 

(1 sample delay combined with itself = comb filter...) If the delay is 

set to 0, everything above the cutoff frequency is appropriately 

passed, so it looks like the delay is actually not necessary, though 

some of the comb filtering effects that it could introduce might be 

useful in accentuating the effect. (though presumably not accurate...)

Anyways, easier still is to just use hp1~ included in the bonus

The simplest of all possible lp filters y[k] = x[k] + x[k-1] has 0.5

The simplest of all possible lp filters y[k] = x[k] + x[k-1] has 0.5 
samples' delay across the board:

Yup. They're in the Pluggo support folders after you install pluggo.
