Let´s clear something out, Padshop and Skylab and Retrolouge 2, Hypnotic Dance and what else is using the same engine in Halion 5-6. So you need to see Halion as the mother ship here. You can do anything in Halion…Like ANY thing with almost no limits. So dive in to Halion, thats where you find what ever you feel you are missing or even if you need a better program understanding. It´s so much simpler in Halion and yet far more advanced 
So Padshop and all the other instruments are just presets for Halion, whats new is sampels and the wavetable editor and new macro pages like the piano.brass and strings and on. You can do the same in the macro editor now btw. You will find nothing more powerful than the Halion 6 sound engine I prommisse you!
But I realy love the Padshop patches, why did Steinberg not make padshop a macro page in Halion too?
