+1 for lemur, the most powerful of all cos you can use scripts and mass rebound factors
I also loved konkreet performer for their amazing interpolation of preset but unfortunately not développer anymore...
I think tc 11 tablet app has midi output too,
Mira app for max msp revealed to be a bit clumsy but can work too,
i admit I lost a bit interest on tablet app after the creative period of lemur and konkreet but I m curious of any newz
