Again, I don't have first hand experience of the rolls controller…. But reading the manual it just sends PC commands (Program Change) and not CC (continuous controller) commands.
So you would be able to do preset changes but you would not be able to do anything like TapTempo, bypass of effects etc…. So I don't think it would grow not being a flexible controller for controlling multiple devices. …. But maybe you do not want the extra features that MIDI CCs would add.
For example it does not send a bypass command so if you wanted an effect on the TimeFactor and Not on the ModFactor… You would have to create a preset on the ModFactor that let nothing through but the dry signal.
You will also still have to use something else for TapTempo… Like one of the Factor Pedals or an external TapTempo switch.
Hope that helps
