I guess that the wish list it's already full but I have two small requests(not so small

)I do not know if someone else is interested or if it already has been asked.
I like to have a filter fm , but not a complete audio-rate modulation(at least not now) that I imagine requires a lot of work.
I'll explain, a low pass filter that can be modulated by an oscillator at audio rate in addition to the others, without changing the existing ones.
I do not know whether this is easy to do

about the second request I'm sure has already been asked and forgive my curiosity.
in the future it will be possible to have an oscillator waveform editor similar to that present in the lfo,mp envelope etc.
something tells me that will be one of the surprises of the next big versions

that's all , not anything else to ask I'm really enjoying mux modular and for me is already amazing thanks

hello, Taifunk,

Taifunk wrote:filter fm

very crude, untested, highly experimental, solution what follows here.

in the modular area, lead the audio output of your oscillator, synthesiser, into one audio splitter, the positive output into one envelope follower, then the modulation output into the filter of your choice, repeat it with the negative side with the addition of one inverter before the negative envelope follower, then fine tune everything, even the modulation cable properties where you can define negative intensity values for the negative modulation side, then with the curves you can low pass filter, round down, or high pass filter, make sharper, the resulting modulation signal.

later, at home, will do the testing, then will post the results, might need some time, though.

enormous fortune that the modulation monitor node already exists, use it.

the oscilloscope, with wide time window settings, showing rather amplitude changes, might also be useful.

before forget to mention, put one limiter on the master, just in case anything goes agley.

one more thing, if my recall is correct, you might need to push up the midi resolution in order to achieve the finest possible evaluation of the modulation signal.

please understand, all this is only the result of the visualisation of what might happen in the program, nothing more.

if you are faster with your successful experiment, please let me know.

all the best...

Hello NadirToZenith and thanks for the tips ,I already experimented but I suppose that the filters do not support fast modulations.
I try to follow your suggestions and see what happens and of course when experiment with these things better and keep the volume down and a limiter, you were right to write I always do but it's always good to remember

All The Best

hello, Taifunk,

Taifunk wrote:the filters do not support fast modulations

they do support the modulation by the steepest envelopes, so, at least in the lower keyboard region, this fake, quasi-audio rate, modulation should work (at least in my dream state).

can not remember, though, through what are the modulation signals evaluated, but if not at audio rate, then perhaps through midi ticks?

all the best, keep up the experimentation, will be home in fifteen hours, able to do the test drive...

ok thanks

in the meantime I did some experiments with tf filter It is arriving almost at hi audio rate but incorrectly I think that modulation is limit at 600 hz via midi and audio,have midishaper I tried with this the lfo comes to high audio frequencies , same thing with the envelope follower, I tried with a pulse wave and experimented a bit with unipolarizer , ring modulator and a hi pass filter before the envelope follower.

great news, excellent results!

try to set up one noise oscillator for the filtered audio, for the modulation oscillator use sine wave (at least first), then you can see, hear, more exactly what this setup is capable of.

back to travel, all the best...

hello, Taifunk,

have experimented with possible solutions, if you are still interested, some time later can upload the resulting node network for the sole purpose of evaluation, the finishing touches will require more time, though.

congratulations for your syntaix release, great work!

all the best...

thank you

I'm glad you like

I wait for your preset, I have tried many combination but unfortunately with bad results

Note that the MUX modulation signals are not suited for audio rate modulations. They can do very fast modulations but if you would go audio rate then it will take too much CPU. Maybe in a future version i'll add support for audio rate modulations. I'd love to have that, but sensitive point is CPU consumption.

Thanks ,I will be happy to wait there's no rush

thanks for your words, eagerly waiting for those times.

the one in progress, called sloppy quasi-fake filter fm synthesiser, strictly in monophonic mode, with the appropriate settings, is quite capable for bass timbres, sounding one octave lower, faked (the modulation oscillator, now, plays one octave lower than the voice one, giving modulation peaks for the filter at every second cycle of the sound).

using the instrument at the lower keyboard region is possible without any problems.

somewhere at the higher octaves, though, it seems, the modulation signal calculation reaches its internal limits, then the system (windows 32 bit presently, osx yet awaits installation) becomes quite unresponsive, including processor usage at full level, requiring whether patience or, in the worst case, forced reset (will find out the highest usable key without the problem, before posting the thing).

please understand, am certainly aware that this phenomenon comes up because of my unintended usage of this gem

, mulab, not because of any innate shortcoming in it.

one question, if allowed, have searched the forum, could not find (quite possibly my mistaken keywords) information about the pivot key of the filter keyboard tracking (or center key of the keyfollow), where the value is neutral, zero, crosses the center line (later might set up some kind of experiment to find it out, but if you can supply the answer, the time can be used for other things).

all the best, thousands of thanks for these great tools again...

accidental double post, please ignore, sorry for this...

NadirToZenith · Post by **NadirToZenith** » Wed Jul 22, 2015 12:32 pm

hello, all concerned,

here are the zipped up project, preset, notes, files.

sloppy quasi-fake filter fm synthesiser.zip

please understand, this version is here only to show that, at some extent, filter frequency modulation is possible (not that anyone stated the opposite).

please read the included notes.

please feel free to optimise it, possibly uses somewhat overcomplicated solutions (review credits, where applicable, will be duly noted).

plans are: to make one version of this with two, three oscillators, with the modulation signal independently mixable from the timbre signal.

all the best...

Thanks NadirToZenith, I tried your preset this is useful to me and I'm learning something are still in the initial phase have yet to learn the different characteristics of mux but for this the only way is to experiment

thanks for trying it, please keep in mind, it still is not one useful instrument preset, just one crude node network to illustrate one of the countless capabilities of mulab.

nearly all of the settings are in their default state, it really needs experimentation, but even if slowly, it will come to it.

my situation is similar, but still only dabbling with, within, the program, some of it becomes, gradually, understood, most of it is still way above my head, even after about two weeks of trying it here and there, whereas you have already released one complex instrument.

will do as planned, when time allows, then will post the ready instrument, with more useful presets, besides other, smaller, things in progress.

wish you much success in your work with the program, all the best, too...
