@deframmentazione-geometrica

you should use a logarithmic line~ object to adjust the curve as smooth as you want.
On top of that you should apply a Nyquist correction to the output of your oscillator abstraction.
So here you have some imagines how to do that. The Nyquist abstraction is used in the output of the triangle oscillator abstraction as an example. Then the final output can be controlled with a logarithmic line~ object.

OBS : If you need more then one oscillator you can apply this for each oscillator and then use a mixer and then the output of the mixer you use again the same idea. In this way you have an oscillator smooth stage control and a final mixer stage control for extra smoothness.

This is just the simple mono smooth control (no curve adjustment)

The same idea but as a stereo version

Here is with logarithmic smooth control (with curve adjustment)

Here you have a Nyquist correction abstraction

Here you have a triangle oscillator with Nyquist correction

You can also download xline~ which is an object that is doing just that :

@randal I hacked up your patch a little so I could run it to see what was going on, in particular I removed the algorithm switch from the voice and just took signal from the carrier. Is this not the result you were looking for?

Note that both oscillators are at the same pitch, and I took care to start them at the same time so they'd be in the same phase. I also think you might have accidentally deleted the feedback path for the modulating oscillator. [edit: I see now that you didn't, but the feedback outlet is post amp attenuation, so there is very little feedback. Additionally, you are using s~/r~ which introduces a 64 sample delay--consider using the technique in my next post]

I only have a passing knowledge of FM, but it seems like you have to keep the modulation index (in your case, op2 amp) really low to get the results you're looking for. I don't know how the DX modulation indexes are scaled. Also, if you're evaluting your results in time domain (i.e. looking at the wave shape) I think the phase between the oscillators is important. Adjusting the tuning of the oscillators while they're running will shift their phase relative to each other.

@seb-harmonik.ar , @whale-av Many thanks for help. So what i want to do is this :

i want to have 2 oscillators (both sine waves. one a carry oscillator and the other one a modulator) with different frequency. And i want their audio signal to be processed in [expr~ ] using bitwise XOR modulation. This is different from [+~] , [-~] , [*~] , [/~]. This paper describes this in detail.

dafx08_13.pdf

Here is a plot of the waveform result using bitwise XOR (from the paper above) :

Here is a schematic view of the oscillator structure :
So to control both oscillators i need to control the theta (phase) , f (frequency) and A (linear amplitude). Also S1 is unipolar. So the idea is that i can use the basic operations on the audio signals like (addition,multiplication,bitwise OR,bitwise AND) or i can use something different (bitwise XOR). So i tried to make somehow the bitwise XOR using a formula : bitwise XOR equivalent <- (S1 | S2) - (S1 & S2) (not working). The bitwise operations like "&" and "|" works for [expr] not [expr~].

Also i just found this about [expr~ ] object so maybe i am missing something or i am wrong
What is this operator "^" it is bitwise XOR ? or exponential ? or something else ?

Thanks to all a lot for the help. I also tried what @alexandros was talking about and it is almost working. But the waveform is really off so i need to learn more about this idea.

Quantizer for oscillator:

Hello everyone I have a oscillator I am using for droning. Is there a way I can quantize it. So basically quantizing the pitch knob so I can snap the oscillator to a scale?

Thank you!

Hi! Relative beginner to PD here. I've been building a pretty basic synth which works fine in PD, but when loading it onto Bela I'm having issues with my analog inputs. With my current patch there is no sound and the connected potentiometers do nothing when turned.

The screenshot shows 2 oscillators which are controlled by one pot. (I am using sliders on the patch to simulate the analog inputs which worked fine for testing in the virtual environment) Essentially, I am using 7 analog inputs to control the frequencies of 14 oscillators. You can see in my screenshot how a toggle switches between two routes (all toggles are either on or off dependent on a master toggle which is my 8th analog input).

I think the reason this isn't working may be to do with using snapshot~ as a way to convert the signal to a control - I guess this isn't creating a continuous value which the patch can use for the frequencies of the oscillators? The list prepend object which defines the 2 routes obviously cannot take an input from the adc, so is there another way to convert this? Or is there some way I could have the input after the list? I've tried a few things out but can't get anything to work.

Thanks!

Even more chaotic 8-step sequencer.

Each step has square wave oscillator, sine wave oscillator, wav file sampler and noise generator.

Lenght of steps can be controlled, overall and individually, and sequentially muted.

Two square wave oscillators modulate each other and a third one modulates the combined two. Optional random frequency modulation on each one of them with control for range and speed.

Sine wave oscillators can be pure, randomized with control of range and tempo, with up/down sweeps or LFO.

Samplers can be set to start and end of loop, playback speed goes from -200% (reverse playback) to 200%.

Generators and left/stereo/right outputs on each step can be sequenced.

Each step has stereo delay.

Recording to wav files possible.

Enjoy.

Hello

i've been mucking about in PD for some years, but lately taking it more serious.. i'd like to share my first patch, that i feel is worth sharing:

it's a chaotic sequencer/rhythmic noise generator.

Each step has square wave oscillator, sine wave oscillator and a wav file sampler.

Two square wave oscillators modulate each other and a third one modulates the combined two. Optional random frequency modulation on each one of them with control for range and speed. Sine wave oscillators can be pure or with up/down sweeps or LFO. Samplers can be set to start and end of loop, playback speed goes from -200% (reverse playback) to 200%. Generators and left/stereo/right outputs on each step can be sequenced.

Bugs: all outputs are set to right on start-up, division by zero on samplers.

@RandLaneFly "Dude... all i can say is thank you." Glad to help. It just happens that I was working on this less than a month ago for a synthesis theory class.

"the fm8 sounds more filled out with high frequencies"

The FM8 plot (bottom left) looks like a lot of aliasing. I'm not sure if that's really "filled out." (And the "FM8 sine tone" plot is definitely not from a pure sine tone. It might be deliberate or it might be just a poor oscillator implementation. One of my former students did some research comparing analog oscillators against digital ones from commercial VSTs. The VSTs are often really awful -- unbelievable amounts of aliasing. Massive is one of the worst offenders. I think this is one of the reasons for the harshness of modern EDM -- adding a lot of noise into the pads is a way to cover the kind of gross sound of the oscillators.)

One thing you might try is to use a wavetable oscillator instead of [cos~]. The wavetable can include a bit extra harmonic content.

Hi! I've done some fm with feedback lately for a Camomile plugin. If you don't mind doing archeology, the patches are here: https://patchstorage.com/pmer/

I think the best way to do multiple operators with feedback is something like this:

your matrix will need to be able to detect feedback paths and route them correctly through the single sample delay. it's possible if an oscillator is fed back into itself and also routed into an earlier oscillator that then feeds the first oscillator you will end up stacking delays? is this true?
