This is a very rough port of the second mvclpf24 implementation from Fons. I'm posting it here so the devs can take a look and see if they think I've done this right. I do not follow the DSP code at all, but thankfully Fons wrote that!

I did have to take some leaps of faith with regards to the how the various LADSPA ports are used in the code. It seems to work nicely, the resonance is very nice I must say, but I'm still not sure I've ported it right. I've no idea what the Exp FM control is for, nor do I understand why the filter frequency goes from -6, 6? Fons used to frequent this list, that's why I posted this under a new subject. Maybe it will grab his attention! If my crude port seems Ok I will do the remaining 3 when I get a chance. Here's an example, and below is the link to the original source. <CsoundSynthesizer> <CsOptions> -odac:hw:0,0 ;;;RT audio out </CsOptions> <CsInstruments> sr = 44100 ksmps = 32 nchnls = 2 0dbfs = 1 ;browse for text files in current directory instr 1 kFrequency init 3; range(-6, 6) kExpFM init 7.5; range(0, 10) kRes init .5; range(0, 1) kResGain init .5; range(0, 1) aInput randi 1, 22050 kFrequency line -6, 5, 6 a1 mvclpf24 aInput, kFrequency, kExpFM, kRes, kResGain outs a1, a1 endin </CsInstruments> <CsScore> i1 0 5 </CsScore> </CsoundSynthesiser> And the link to the originals is http://users.skynet.be/solaris/linuxaudio/downloads/MCP-plugins-0.3.0.tar.bz2 On 9 January 2016 at 22:51, Victor Lazzarini <Victor.Lazzarini@nuim.ie> wrote:

Would the 6 range be actually 6.28.... which is 2pi? Not looked at the code, but this jumped at me. Victor Lazzarini Dean of Arts, Celtic Studies, and Philosophy Maynooth University Ireland

It's raining where I am! Anyhow, I just grabbed the same ranges that appear in his LADSPA descriptions. See below. I'll not be able to do anything more on this for the next few days. Real work is calling! But when things settle down I'll look at the the others ones. { LADSPA_HINT_BOUNDED_BELOW | LADSPA_HINT_BOUNDED_ABOVE | LADSPA_HINT_DEFAULT_0, -6, 6 }, { LADSPA_HINT_BOUNDED_BELOW | LADSPA_HINT_BOUNDED_ABOVE, 0, 10 }, { LADSPA_HINT_BOUNDED_BELOW | LADSPA_HINT_BOUNDED_ABOVE, 0, 1 }, { LADSPA_HINT_BOUNDED_BELOW | LADSPA_HINT_BOUNDED_ABOVE, 0, 1 }, { LADSPA_HINT_BOUNDED_BELOW | LADSPA_HINT_BOUNDED_ABOVE | LADSPA_HINT_DEFAULT_0, -15, 15 }, On 10 January 2016 at 12:48, Victor Lazzarini <Victor.Lazzarini@nuim.ie> wrote:
