Striso with V3 Sound Module

Has anyone any experience of using a Striso Board with a V3 Sound Module, please? I am finding that the Striso will only work with the default piano voice – any attempt to change the voice via the V3 App, either with the Striso attached or attached after selecting the required voice, results in no further response to the Striso keys.

Any help would be much appreciated.

PS: Regarding another subject on the forum, a Striso/iPad combination works fine with a 5.5v rechargeable l-ion battery, through a hub.
