Great. I’ve Made further progress. Can now choose which type of parameter to alter so can deal for example with `with_fx :pan` or `with_fx ;reverb`. I now have an example with three nested fx for pan, level and reverb and all are controlled independently within the loop at different times.

EDIT ADD  
I’m also working on a touchOSC input controller for this. Initial experiments working OK, and so far I’m controlling the amp of a live\_loop with fades up and down and “wave” remotely. Now working to allow several controllers together.
