how to tune inharmonic sounds in FM synthesis

[Tweaking Knobs]

when creating metallic sounds with operator by using detuned modulators how do you tune the sound to a certain note say "C" ?


because most of the times the sound comes up metallic yes, but is not in tune .


Is there a way to tune the result ? without sampling, and without filtering ? just with fm ?


And what are normally hi hats tuned to ? C , G ?


Thanx !

Keeping the width of the highest peak of waveform will reduce the detuned flavor I think. Watch the osciloscope.

don't know if there's a tuning to hhats..
as far as I know they are considered non-tuned percussion..

Indefinite pitch

Instruments in this group are sometimes referred to as "non-pitched", "unpitched", or "untuned". This phenomenon occurs when the resultant sound of the instrument contains complex frequencies through which no discernible pitch can be heard.

Examples of percussion instruments with indefinite pitch:

Bass drum
Castanets
Cymbals
Rainstick
Slapstick or whip
Snare drum
Tamtam
Tom-tom

Ive read those, but they dont say shit about tuning.

Thanx anyway for pointing them out


Any more ideas ?

any fm master in here ? robert henke ?

I'm not an FM masster, but I believe that the reason Yamaha implemented its DX7 series the way they did is because it is impossible to tune true FM patches. They actually implemented phase mod not frequencey mod synthesis. Phase mod preserves the harmonic relayionships of the carrier to its assigned pitch, FM does not and I believe cannot do this due to the fact that you are actuallly changing the frquency of the cazrrier.

Either use the transpose setting to pull the note back to the right key, sample the sound out and plop it into sampler, learn to make sounds that stay in tune, or embrace the fact that not all sounds you make in Operator will be 'playable'.

Some of those great sounds you can get out of it are precisely because it gets dissonant on certain keys.
