This is what your G2 does in it's sleep Wink

The patch has no sound generation modules at all. Its sound comes from the noise in the inputs. The patch started off as some sound design stuff for uni but when I stopped feeding stuff to the inputs it kept making sound so I tweaked it a little and played around a bit.

There are 3 variations (1 2 and 3) that correspond to the alpha, delta and theta sleep states of the G2 Wink

The patch is nice, but how happy should we be with this ?

Did a little test, see attached. There is quite some noise and when I fully open the patch level it starts to oscillate sometimes. Set the switch to position one for this.

For comparison I added a noise module, switch at position two for that, it's different.

Could the inputs be a source for 'real' random maybe ?

They do indeed sound different. I kinda like the idea of using something truly random for random generation, it might add some sort of realism or true natural chaos to mathematical patches. Oh, and as long as you're not using the inputs for anything else, you've got 4 different sources Smile.

I'm not unhappy with this noise. One should expect a certain amount of noise to go with the analog inputs and outputs of any device. I've never noticed the noise before (and at times I run my speakers quite loudly) which means it's low enough for most uses. IMO the noise floor is more than adequate.

The test for me was gaining one of the bus inputs as far as I could be bothered and there wasn't any noise at all (as it should be, as it is simply multiplying the number 0). Some old samplers used to have gain noise - you would apply gain multiple times to a new blank sample and you'd end up with digital noise from shoddy programming.

The gain in BH's patch is 4096x, so imho opinion it isn't that strange that you pickup something there. Maybe the new G2 converters are even better at being a random source than the classic ones with fewer bits. I reckon that, even as they have a better s/n ratio, the noise floor noise might actually be more random noise (better noise? is there such a thing?) but with more 'real signal headroom' above it. I guess the first couple of bits in a 24 bit AD conv are more sensitive to be affected by anything than the AD conv's with lower bit specs. Or is this pure nonsense?

To pick up something, yes. But 4096 amounts to about 36 dB and I get an output signal that almost hits the clip level, something I did not quite expect.

The measurement should have been done with inputs connected to some impedance, which would have given less noise probably. I remember having done this experiment with the NM classic as well, and that one was not very suitable as a noise generator.

It's not that input noise had been bothering me, but the numbers surprised me a bit.

Jan, I had also calculated the 36 dB value after I posted my previous message, and wondered whether I had done something wrong or missed something. Indeed, that doesn't sound good. However, plugging in my bass (I do that a lot) after the preamp stage works better in the G2 than in my old MM, as I don't hear any obviously added noise (either of them), but I do have far more headroom before the input clips in my G2.

A bit OT: there is one thing I seem to notice about the AD's and DA's on the G2. If I run my bass through the engine, with no processing other than in/out and some mixer things, the signal seems to be brighter than origal. Possibly a bit less 'deep lows'. Anyone notice this too?

Did you have the inputs connected to the other gear, which was turned off at the time, or the volume was truend all the way down on the external gear, or were there no cables physically connected to the inputs at all?
