All good, it does the job. In case that could be useful to anybody: I use the extension pipe and the HS40TPN with a Roland PDX-8 10" pad. At the lowest possible setting (pipe and extension pipe fully inserted, base fully spread), the pad stands at 69 cm from the floor. At the highest possible setting (pipe and extension pipe fully extended, base folded but still stable), the pad stands at 104 cm from the floor.
