Not sure if I have missed an obvious resource to view Pure Data conversions into max

I have a PD patch with "bp~" in it, what is this in max

pd-max

I don't know about obvious, but there are Stefan Tiedje's PD Abhaxions which you'll find on the old Share pages -

My guess would be a bandpass filter?

1. Look up the help file for the Pd object to see what it does [in this case, it's a bandpass filter]

2. In Max, choose Help > Max Help. Type a word related to what you found out in #1 into the search box

3. See what comes up. If there's more than one result, look at 'em all. You may meet a new object that way.

4. If nothing comes up, try another phrase related to what you found in #1. Investigate *those* in the hope of meeting new objects.

5. If nothing shows up that way, ask on the Forum.

In your case, it would appear that reson~ or svf would be useful things to check out.


I have tried converting the 'bp~ 2519 69' into 'reson~ 2519 69' but I am not getting any output :/

I will post the patch, don't suppose you can see the problem.

reson~ needs 3 attributes (gain, frequency, and Q) to work.

Here's your patch corrected.


sombody already told you nicely to look at help files.

Reson~wants as arguments:
gain, center frequency, q

bp~ is indeed a 2-pole bandpass filter, as is reson~, but that does not mean they are remotely similar. if you are porting general Pd patches and just need 'something similar', use reson~ or svf~ or filtercoef~ + biquad~.

"[bp~] only implements feedback sections, not a feed-forward section as [reson~] does; the filtering (peak) is less extreme in [bp~]; it is a lot 'richer', especially when cascading"

so, if you need an exact replica of the sound and response of bp~, i have only come across two max patches that do it (although i am sure there are many more). 1, by volker böhm, using biquad, and 2, by me, using gen~ (which is not technically bp~ as it uses signal rate update, but sounds exactly like it). i tend to use the volker böhm solution. you can find both patches towards the end of this thread:
