yes, I also think it is a brilliant tool and complements Sonic Pi very well. I am still working on my Live Looper and will release a stable version as soon as possible (I did some tests jamming with a friend and need to check and adjust things…).
In some cases while making music with Sonic Pi I find it very convenient to have an easy to use touch interface (especially while recording and playing back) and to separate control tasks from textbased live coding.
It is also brilliant because you can adjust the interface as it suits you and also very easily update the layout on your end device. Another thing: You can create a layout group to easily switch layouts (especially if you are using it on a smartphone with restricted layout space like me).
I am looking forward to explore more use cases … Actually you were the one to get me going! Thanks especially for your documentation work, which makes things accessible for others!
PS.: Next time I am working on it I will check out
