Since Reason 12 now has a full re-worked Combinator, it would be nice to have some of the backside controls of the Rack Extensions at least available as automation targets.
This would allow me to create a Combinator, which has for example all relevant controls of a filter or an FX available.
See this example of The Legend Filter, which does not have the Saturation and Compensation available, which are only available at the backside:

Another problem of the REs is, that the instrument must be triggered via a gate+note to produce an output of the external connection. I found a workaround for this, but it would be really helpful, if this could be changed, maybe with a switch.
