Duplicating a single module at a time is painful. It would be very helpful if we could select multiple modules and duplicate them in a group.
The simplest solution to duplicate modules in one patch I could think of is to run multiple instances of miRack in my host Drambo sequencing my one shot sampler patches with polybeat note by note applying the effects output by output to taste. I can go between macOS and iOS with miRack and Drambo. I would love to see duplication added, though.
