I understand Dave, and I'm sure if you were mult-tracking, you'd probably be using the SV1 for Rhodes (maybe not, depends on what the SD60 has to offer). I also understand that in a live (stream) situation, you want to keep the configuration as simple as possible to minimize operational errors - hence, the single keyboard approach. As others have said, keep putting them out; each performance will teach you a little something new that will enhance future performances. With your vocals, NONE of them is going to be BAD, it's just ANYthing can be improved, especially from a production point of view.
