Absolutely, thye Noise Ring operates on a fixed algorithm that 
could be emulated with a general purpose computer like the 
PSIM-1. You do not NEED a Noise Ring with the PSIM-1.

That said, hard core aleatoric fanatics like the Doc and myself 
will be using external random sources as they have parameter 
controls that are more satisfactorly done in a random source 
module.

Also, a bit of history on "aleatoric" music. "Alea" is the Latin work 
for a die, or single dice. The origin is probably from Mozart, who's 
"Dice Music" is famous as an example of music form the 1700's 
which included indeterminacy.

Musically, the composer acts as the "result" monitor, and 
decides if the indeterminate patterns fit the human criteria of 
"music".

The use of indeterminacy in music composition, forms one half 
of a "Monte Carlo" algorithm. The first half is to generate some 
input patterns using indeterminate (non-repeatable) methods. In 
mathematics, this is called a "Monte Carlo" method and was 
used to solve equations with too many variables for traditional 
mathematical solutions.

The method involves making a mathematic model of a process, 
applying random number generators to each variable input and 
monitor the output for the desired result. When the result is 
reached, record the input values and you have your solution. One 
practical example is predicting stress forces from the sloshing of 
rocket fuel in fuel tanks.

mathematics, see "Random Process Simulation and 
Measurements" by Granino A. Korn. MacGraw-Hill Book
