The MoPho white noise generator... weird.

[Number 6]

Ok, maybe it's just me then.

Maybe I'll add a soundclip to the thread when I'm next in the studio.

I'd like to hear that. Mopho/Tetr4 are on my wanted list, as is P08 (somewhere). I'd like to know if the P08 has the same noise source.

Pleasant white noise is really prettly simple to generate in analogue electronics, so if they have gone for something different, I guess there was an aesthetic reason. Maybe more of a characteristic sound?

I know exactly what you mean.

The white noise on the Mopho is not your standard white noise...it's ok at low levels and adds a grit to sounds, but it sounds like a lo-fi sample being looped to my ears....isn't it digital generated? sounds nothing like pure analogue white noise. Anyway, it's different!

Love the mopho, but i couldnt agree with more about the sound of the noise.
Its nice to modulate things with it however..

That's exactly it, Mike. I thought I (or my MoPho) was going crazy.

@Oli - It is a characteristic sound, so I'm assuming the same thing as you. I don't think it's a bad thing really - it's good to have a white noise that sounds a bit different.

@ steffensen - It comes into it's own when using it for modulation. I like it.

Question about the noise generator, is this just something to use as an effect, or is it necessary to include this noise to make the sounds?

Just basically wanted to know if I could use this synth to make all analog sounds, and not have the digital noise in the sound?. thx

Absolutely not.

[Lowas]

Agree on the noise generator on the mopho.

To answer this question: noise is used for a variety of things. Percussive sounds (snares, toms, cymbals). Effects sounds (surf, wind, etc.). If you have parallel filters or an envelope for a single oscillator (noise is sometimes classified as an oscillator instead of added in the mixer) you can create a short burst of noise as a "click" which adds a certain character to leads/bass sounds.

Another option is to add a little bit of noise to the sound and then put a phaser or flanger over the end result; it "tunes" the noise and turns it into something melodic.

If you're not making any of types of sounds specified above, then you don't need noise. Whether it's digital noise or not is besides the point.

There are various implementations for noise generators: a pseudorandom generator generating at a frequency that's high enough can do the job. However, if the randomization cycle is too short (that's why it's pseudorandom; it eventually repeats) you can start to hear the looping effect.

I use a tad of noise (filtered) on a few Mopho patches sometimes. But for your standard white noise sound I just use Operator or a vst normally.

[G. Kaye]

^Thanks for the responses guys.

I mainly just want to use the mopho to make basic all analog leads and basses, no effects or added percussive sounds are really necessary I guess.

Also, I've read that the 2 sub-oscillators are actually digital, is this true?

From the tempest thread, via Pym...

We don't have analog noise on any of our products, the noise is from a digital source. Noise from an analog source is extremely limited in color unless you add filters, which adds a lot of cost. The noise samples that are in the Tempest were created for us using a modular rig and give a lot more variety.

the mopho/tetra/p08 dont have samples though so how is the digital noise generated . from the dsp that does the env/lfos/modulations ?

No, they are as analog as DCOs.

MoPho people, listen to unfiltered noise on yours and see what you think. Am I talking out my ?

Upload a sound clip so I can analyze it! I don't recall hearing anything like that on the Prophet 08 I used to have though.
