Relevant now, with the introduction of the 4ms MetaModule, a Eurorack module that is confgurable with a wide variety of VCV modules, that can function in many ways similar to the G2, and could also be configured into a system with other Eurorack modules.
One option with this would be to use the MetaModule, in a Eurorack keyboard, like for instance the Cre8audio NiftyKEYZ. ( thread )
I like Loopop’s idea of doing quadraphonic sound with this.
