Hi , to use harmonic



if a modulator is set to an even ratio,

half , two or four times the oscilator pitch , you add harmonic overtones like these :


1:1
1:1
2:1
3:1


, how does this works in zebra to get tuned sounds ?


thanx!

It currently works by ear, but some people also made tuning tables. I think these were posted here... (too late now for me to search them, I really need to go to bed...)

is this fixed in 2.5 ?


pleeeeeeeeeeeeeeeeeeeeeeeeeease?

Why fixed? It's not a bug. Tuning is done in semitones. It would be really bad if tuning was only in harmonics (the number of complaints would skyrocket). It may however be cool to ahve an *option* for convenience. But it's definately not a bug. I'll see if I can squeeze that in, but no promises.

Yeah, the freely adjustable ability to create all kinds of dissonant mayhem is way more appealing than being locked in to proper intervals. Coming from Ableton's Operator, Zebra's fm kind of scared me at first, but I'm using Zebra an awful lot more than Operator these days. :)

Because synths should make the whole song by pressing only one key and bouncing it.. for those deaf people :D

ha ha, very funny , by the sameway of thinking we should sequence manually everything instead of using a computer :wink:

In fact that was the deal in the early days of midi. Lot's of people thought that using midi was cheating and for talantless people.

But to help you. I think that SynthSquad has one synth that could do harmonic fm. Maybe you should check it out?
Personaly I like the idea of free tuning. Although for some cases an independent harmonic fm module would be cool too.

Well, if you look at Bazille, it has already got the option to tune oscs harmonically. I'll add it at some point but it's simply not as high priority as e.g. fixing real bugs.

Cheers,

hey urs , one question please

im learning fm synthesis this is what i understand:


A Carrier is modulated by a Modualtor , if the modulator is very low the sound is like a police siren
if the modulator goes higher than 30hz then the more harmonics are created and the pitch goes higher everytime.
so , if you use a ratio like 1:2 you get harmonic sidebands , because the freq of the modulator is the double.





My question is :

if my sound is on C3 and i modulate it with a modulator with the double of freq than my carrier (1:2 right?) ,
how much is that in tones ? C3 plus D3 , or one octave higher ?


thanx!

2:1 = one octave up (1200 cents)
3:1 = octave plus perfect fifth (~ 1902 cents)
4:1 = two octaves (2400 cents)
5:1 = two octaves plus major third (~ 2786 cents)
6:1 = two octaves plus perfect fifth (~ 3102 cents)
7:1 = two octaves plus harmonic seventh (~ 3369 cents)
etc.

If you like 80s retro sounds, check out my latest tune…

It's one octave. 1 octave = double frequency

Tuning the modulator up in semitones has even ratios at 12, 19.02, 24, somewhat above 27, 31, 36 etc... there must be a table somewhere...

great thanx!


what does even means ? do you know a sinonim ,

does it means integrers ?


thanx!


and also , how is that table called , i googled tones to ratio table but nothing comes up.
