SDRuno is the front end app from SDRplay. The original was just recently acquired from Sandro the sole developer of Studio1. Myself and a few others are part of the beta test team.
I will be adding more videos on YouTube covering almost all the features SDRuno.
Another project I'm working on (along with Paul J. NN4F) is the SDRuno "Cookbook" It covers most if not all of the features of SDRuno. It is a work in progress. The PDF is available now and will always be located at NN4F.COM
