Hello,

Attached is a sound file. The beeps in this sound so nice and seem so deceptively easy to imitate.

When I look at them, what I see is a base osc with another osc added that is modulated by a phasor.

Here is my patch:

Unfortunately it sounds NOTHING like those beeps and this is frustrating me to no end snd file attached for those curious

Hi Genjix,
I'm at work and can't listen to the file but from what you wrote it sounds like you want to do an fm patch? In the patch you have you are adding two sine tones not modulating the carrier frequency. the [+~] should go between the the [osc~] and [mtof~].

here is a simple example

#N canvas 363 261 467 354 10;
#X obj 91 234 osc~;
#X obj 91 197 +~;
#X obj 92 85 mtof~;
#X obj 139 142 osc~;
#X obj 139 173 *~;
#X obj 139 114 *~;
#X obj 90 270 output~;
#X obj 95 31 hsl 128 15 0 127 0 1 empty empty empty -2 -8 0 10 -262144
-1 -1 3500 1;
#X obj 195 89 nbx 5 14 -1e+37 1e+37 0 1 empty empty empty 0 -8 0 10
-262144 -1 -1 0.2 256;
#X obj 194 159 nbx 5 14 -1e+37 1e+37 0 1 empty empty empty 0 -8 0 10
-262144 -1 -1 580 256;
#X text 107 6 Carrier frequency;
#X text 266 160 modulation index;
#X text 261 87 modulator frequency;
#X connect 0 0 6 0;
#X connect 0 0 6 1;
#X connect 1 0 0 0;
#X connect 2 0 1 0;
#X connect 2 0 5 0;
#X connect 3 0 4 0;
#X connect 4 0 1 1;
#X connect 5 0 3 0;
#X connect 7 0 2 0;
#X connect 8 0 5 1;
#X connect 9 0 4 1;

it is an FM sound - there are FM synths here and in Miller's example patches.

"The beeps in this sound so nice" is a subjective statement, people here (and elsewhere) may not share your emotion

hey thanks for your answers. i tried that patch thanks and went and read about fm synths... but still i can only produce ugly sounds

i try a lot of values... the closest i've got, is this patch

but its just an annoying tone. ah maybe its cos im not so good with pd yet

I took a quick stab at this. It's not dead on, but I think it's close enough to get you going. It's a stacked three-operator FM patch (using the PM approach) with a some [freeverb~].

@mmb

nice patch

I know fm/pm has some variations but it seems unintentional that your phasemodulation runs out off indicies.
So... I know you know put a [wrap~] between the [+~ ] and the [tabread4~] or use [cos~] where the input is wrapped.

attached is my variation

Oh, crap, I forgot about that! Thanks for pointing that out. And thanks for the link, I'll dig into it.
