Controle Rate in A Signal Rate System

Hi,

I'm working on a architecture between control-rate logic (Markov / prob) and signal-rate timing (phasor~).

My goal is:

• A continuous masterphasor acts as the only time source.

• I want to divide this phase into N segments (e.g. 4 ).

• A Markov / prob system (control rate) outputs discrete states (e.g. 1–4).

• Depending on the current state, exactly one segment of the phase should be active (e.g. as a gate or trigger source).

• Crucially: all timing should remain sample-accurate in the signal domain (no event-based timing).

My current approach was:

• Using subdiv~ and taking the index from its right outlet

• Comparing that index with the prob output using ==~

However, the right outlet of subdiv~ is control-rate, which effectively means I'm doing:
signal → control → back to signal, which i red in the forum many times seems not a good idea right?

This feels conceptually wrong, since it reintroduces scheduler timing into what should be a purely signal-driven system.

So my questions is:

How can I derive discrete segment indices (e.g. 0–3) directly from a phasor~, entirely in the signal domain whilst using weighted propability transitions generated in the controle rate domain (prob) ?

Thx!!!
