We prove an SL 2 (Z)-invariance property of multivariable trace functions on modules for a regular VOA. Applying this result, we provide a proof of the inversion transformation formula for Siegel theta series. As another application, we show that if V is a simple regular VOA containing a simple regular subVOA U whose commutant U c is simple, regular, and satisfies (U c) c= U, then all simple U-modules appear in some simple V-module.
