No. Currently we have prototypes of three totally different types of thru-zero VCOs to be in the starting blocks:

a quadrature version with sine/cosine outputs (prefect sine/cosine outputs, much better than sine waveshapers): A-110-4
a triangle core version (with waveshapers for saw, rectangle and sine): A-110-3
a trapezoid core version (with waveshapers, based on Don Tillman's idea and with his permission): A-110-5 ( )

A-110-4 will be manufactured early in 2015. We still have some problems with the A-110-3 and A-110-5 because the prototypes produced
so far behave a bit different and we still have to find out the reason and fix the problems.

A-110-2 (final version), A-110-3 and A-110-4 will be introduced at NAMM in January (as well as A-147-2, A-138u, A-160-2, final
versions of A-101-6, A-190-5 and A-157, and maybe some more).
