TomDog54 - yes I used the Etherwave Plus because of its three separate CV outs connected to my modular setup. It's just Microsoft Powerpoint for the drawings.
All Eurorack modules have CV in so the only issue is getting cables or adapters that have a 1/4 mono connector on one end for the Etherwave CV outs to 1/4" mono for the Eurorack inputs.
And you don't have to tell me about that pull. Forget two colliding black holes - if someone wants to see gravity waves just direct the antenna towards the Eurorack gear.
