Now you've gone and dipped into the pool of the unresearched.
How do analog oscillators drift, and where do we find that data?

The worstest thing about random is that computers don't like random.
IIRC, the AN1x doesn't have a random function for any parameter.

I've tried this idea with a couple of samplers.
It can be pretty interesting if there is a random function.
If not, it can sound a lot like looping.

One idea is to map velocity or key to change the envelope generator in some way.
Sort of pseudo-random will result.
