In this paper, we design a class of general split-step methods for solving Itô stochastic differential systems, in which the drift or deterministic increment function can be taken
from special ordinary differential equations solver, based on the harmonic-mean. This method is
justified to have a strong convergence order of $\frac{1}{2}$. Further, we investigate mean-square stability
of the proposed method for linear scalar stochastic differential equation. Finally, some examples
are included to demonstrate the validity and efficiency of the introduced scheme.
