Hello.
For people has read my topics under other pages I wanna say this: hope will all be ok as soon as possible, so I'll resume my modular experiences.

Any hints to get odd harmonics frequencies with modular modules?

I'd imagine that you could use the "sineOSC partial" oscillators, set those to the harmonic frequencies that you desire and then mix the results together.

Thank you for reply.

Is frequency divider suitable for drive oscillators?
Does exists a thirdy part multiplicative frequency shifter for incoming wave signals or I can add it to the wishlist?

I would have thought so, and the frequency multiplier too.

I think that you could pass the same base frequency signal into e.g. multiple frequency multipliers (or multiple partial oscs) to create the harmonic series you're after.

2 ways,
first, as proposed above, by using additive synthesis, ie mixing together sine wave set to fundamental frequency, 3rd, 5th and so on harmonic (frequency multipliers are perfect for this)
second,
using FM synthesis with carrier set to fundamental and modulator to 2nd harmonic (ie an octave above carrier)
you don't get control over particular partials' level then, but it is way easier on resources (and to patch :wink: )
just because you cannot imagine something that doesn't exclude it from reality.

So I can feed audio signals in freq inputs...

would make no sense,
freq multiplier is not frequency shifter,
it is plain value multiplier to be fed with frequecy control signal.
you can get similar effect with x/y divider and constant val (way less precise tho' :wink: )

No...you'd somehow need to somehow generate the frequency control signal Michu indicated.

Your audio signal would typically already be full of harmonics unless you're talking about a pure sine wave (the only waveform as far as I know which doesn't have any).

As an example, if you were playing the sounds (i.e. generating your audio) using a MIDI keyboard, you could then use the MVC module to generate the frequency control signal based on the MIDI note being played, create your harmonic sequence using that and then mix that in with the audio.

What are you trying to do, exactly?

Hey Cochise - i would recommend downloading as many patches as you like from the Z - the hints are all there :smile:

I knew virtually nothing of electronic synthesis in my pre Z days, now it's becoming as familiar to me as other musical endeavours, because of the patches of Megerov, Alfonso, Michu, ReD_mUZe, roy thinnes, at0m, etc.,

- those patchers come to mind as inspired & educational, off the top of my head.

oh yeah, and not least kensuguro aah, i've left bucketloads of people out, sorry :grin:

There is as much as you will need here, delve around a bit with the search function :wink:

And get Flexor, if you wanna send audio signals to stuff... :grin:

So add harmonics to a signal different from a simple sine could be like changing the EQ.
But some signals quite totally lack some frequencies; how enrich them?
May be creating a track playing the same notes, but with a compensating tone...

in Modular III stock patches there is "Addi8", a typical additive synth that is light enough but offers a wide range of sonic possibilities.

Thank you.
I'll try out
