Can Alesis recommend accesories for turning Samplepad Pro into a full kit, as advertised ?

Hello. My question is about turning Samplepad Pro into a full kit:

Alesis ́s information on the Sample Pad Pro states that "Adding pads and pedals can transform your SamplePad Pro from a percussion powerhouse into a full-blown electronic drum kit for the on-the-go performer.". (See this link:

Now, what would be the recommendable external hi-hat controller and snare that work properly with SPP? It seems by reading the related threads, that there are various incompatibilities with products from top brands, and even with alesis products. (ie: RealHat; pro X hihat).

Many thanks in advance
