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.
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
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.
