PM.Ladder~: Moog Ladder Filter

Here is my port of the Moog ladder filter written using gen~ (Max 6 only).  It uses the ICST implementation, with a few added goodies such as additional filter modes (notch doesn't work so great...) and peak-shaping.

It has built-in saturation and can self-oscillate.  Filter cutoff is specified in MIDI pitch rather than frequency.

The help-file provides a demo of a monosynth and has controls for key-following, the filter envelope, cutoff, etc.

Very nice, as are your other filters. Is it possible in gen to build a method to crossfade between the filter types? Or are phase issues a problem.

Should be very possible. None of the other filter shapes are in the feedback path, IIRC.

Cool, for now I just routed the different filters to separate outs and did a non-gen crossfade between the responses. Thanks

Hi, using this filter in a project to create a simple poly synth in Max. I've managed to implement it really well, but struggling with the Cutoff control. I'd really like to be able to control the cutoff with a live.dial that shows the actual frequency range of the filter, rather than the MIDI values given in the example patch. I've experimented a lot with scaling in different ways, and done some pretty heavy simultaneous equations to work out the relationships I'd need, but none of it has worked. Can anyone point me in the right direction?

Thanks

Hello. This link seems to be broken.
Is there somewhere else I might be able to download this?
I would love to try it out.
Thank you :)

Since you're looking for a copy of the filter, this may be of interest to you (see the end of the article).

Would be just great if someone still had this gen-patch and would like to share....
