How keep the tune when you inject noise in an oscillator?
HI List,
I have a little problem . I can't keep the tune of a synth when I inject noise in a oscillator .I'm pretty sure there is something to do with a expr but i don't know why.
Someone can help me ?
Thanks by advance.

It's detuning because you're adding noise to the *frequency*, not the output of your oscillator - I couldn't see all of this patch as there are elements missing, your subpatch [banger 2].
insert the [+~] and [noise~] AFTER the [saw~]

if you modulate the incoming frequency of an oscillator by plus/minus 200. Hz at a speed equivalent to your current sampling rate, as you have done in this patch of yours, then no, it is not possible to 'tune' the oscillator as you ask, because it is being considerably re-tuned all the time!
it is unclear what you are trying to achieve. do you want a subtle noisey oscillator? or do you want to do some sort of 'modulation' effect? some quick thoughts:
You're injecting noise into the tuning of the oscillator in your example, and you're also adding a huge amount of it (±200 to the existing MIDI scaled value! ±1 would be a whole step in either direction from the original tuning) If you just want to add noise, add it after the oscillator (send it to the same object that the oscillator is going to)
You might also consider adding pink noise instead as it won't be as harsh. (pink~)
thanks a lot for your answers ,
I want just a noisy oscillator but tune
I like the sound of them .
it's not to add noise after the oscillator.
I will try your system pid.
Thanks a lot
