I am trying to make a patch that recreates the Maihak W49 Filter used in Stockhausen's "Mikrophonie I"

It is a bandpass filter with a frequency range of 30Hz to 10kHz and a steep cutoff.

Right now I'm using the filtergraph~ object with the biquad~ object, I have one as a highpass and that is going into one that is a lowpass filter

this then goes through a signal fader then to dac~

The trouble I am having is that the cutoff isn't very steep, and also there is a delay that happens sometimes (but not always), there is anywhere between one long delay, or 3 or 4 shorter delays.

I haven't been able to find much information on bandpass filters in Max/MSP and this is the only way I've figured how to do it... any help would be greatly appreciated..

how about something like this as a starting point?

wow, thank you this is what I'm looking for! I was just trying to figure out how to use the cascade for this!

I think I get what's going on in this patch... I'll be back if I've got more questions

this is great! does anyone have an updated version of the patch for Max 6? or is there a way to translate this into Max 6?

This Max5 compressed text format should open fine in Max6.

Hi Michael, did you finished the Mikrophonie I patch ? I want to play this piece but I don't any idea of how to make this patch for my self ? Do you mind to share the patch ? Maybe there is a place were I can purchase the patch.

Dear maxers, I'm trying to rebuild the W49 of Mikrophonie I and I would like to know where to find the Q factor and also the db/octave that this filter decreases. Does anybody maybe know any bibliography about this issue?

Hoping to hear soon from you.

@ Peret Attached is a pdf from the IRT out of the "Braunbuch", where you can see the curves. But implementing the filter-curves in Max is one thing, playing the special layout of the fader is important.

Wow! Merci Klangschmied. Is very awesome the manual you've shared. Yes, I know. I was following performances in youtube and following score. It's now a first view work. However, I love it. Thank you very much again.
