Only in terms of tonality though, otherwise low toms made with noise or other sounds of a similar vein wouldnt be consistent on each note on. There's no way you are going to get a consistent fundamental from noise as far as i can tell but sounds made from noise, do not to my ears sound like frequencies come and go.

Obviously being random it must do but how fast is it happening? Maybe too fast for the ear to notice which makes it 'stable' at least to human perception. There must be a probability factor that all frequencies are present at all times, they call it psd (power spectral density).

If, like the OP you bp filter noise, you do to some degree get a workable oscillator, I read somewhere that bp filtered noise actually helped construct those 'spectral' patches on earlier roland digital synths. Its interesting anyway, i wont be trying it any time soon but stuff like this makes me want to experiment.

Didn't find the time to respond until now. For those who're interested, I've uploaded my ableton file so you can see how I made this bass (It's really really simple).

it would probably serious mess with the bass speakers in a soundsystem.

It's not always easy to hear if a bass will sound good on a soundsystem here at home. My monitors aren't the best, and the room I'm using isn't acoustically handled. So if you say it sounds muddy I'll just have to trust you. But your theory seems plausible.

Just a BP filter with 12dB/octave. But actually I started with brown noise rather than white noise, so that's why you only hear the lowest frequencies.

Yes.
AK wrote:Try this, a few 8ve's higher, play yourself a 3 note chord and see if it is clearly percievable, you can do that with a bass tone. If its a muddle, id go percussive with the sound, if its clear, id be happy using it as a bass tone

It sounds like noise, lol. :lol:

bass @ 1.00 on both.
That was acctually the kind of bass I was aiming at, but more in stabs instead of constantly rumbling. :o
