One of the best Cubase remote scripts I’ve seen to date is for the Keylab mkII.
It is a very well done remote that features paging (each control can do many things by using drum pads 13-16 as ‘shift/ctrl/alt/fn’ controls (If you need them to become actual drum pads, switch to a user preset). It’s very well designed and extremely useful.
For areas where the new remote scripting engine is still lacking…this setup makes no excuses. Instead it ‘also’ hooks into Mackie Universal Control aspect of Cubase and ‘gets it done’. A few ‘optional’ features still use the legacy remote system I think; but, the important thing is that it flat out works, and does a GREAT JOB. You really can ‘drive’ a Cubase Session and barely touch your mouse or computer keyboard! This script makes the mkII and Cubase blend together more like a seamless ‘workstation keyboard’ 
mchantzi here on the forums maintains it, and it’s chock full of masterful scripting techniques to ‘learn from’.
