Here is look on LA made by AZZIN in Arch – Alberto Zin – Architect. 
     – since Arch is audiorate, this patch imo nicely demonstrates differences between audio-rate and typical patch environment using cca ms range. It is clear that some stuff are more straightforward and precise, while some are had to make done.. like typical dynamic clock w/ metro-float and +1.
– constants are in typical set up: σ = 10, β = 8/3 and ρ = 28
          – Sigma is marked as “a” (for x), Rho as “r” (y) w/ 8/3 (2.66.) and B (z). (3 vertically white objects in upper left part)
– initial position values are 1,3, 1,2 and 1,6 – the values are closed together so in typical constants one can expect butterfly fx. (3 horizontally white objects in upper part)
Dt 0,005 is probably step size – smallest unit. (object marked as dt)
Memory, store and load are for value triggering, which order is surprisingly define by order module (unlike in Pd, triggers are going from left to right): so first load goes z, y, x initial values, and then trigger goes x, y, z for multiplying constants and then delta-time (Dt).
“x” and “-” are regular math operator * and -. 
Init, a, b, r, step are inlets and X, Y, Z bottom modules (not fully seen) outlets.
           – according to documentation, INIT values are already initialized and step is recommended in typical set up for metronome (clock – can be 1ms in Pd).
