You can do these things now using a midi controller to control BeatBuddy. This thread is about an iPad app to control BeatBuddy from “somewhere besides the floor.”
You can use any midi controller you like, mounted anywhere you like. You can put one on your table top, on your mic stand, at your feet, in your digital audio software, in the living room, wherever you can send midi to the BeatBuddy using wires, bluetooth, or even wifi. You can use a portable phone, an iPad, a computer, or any device that can be used to send midi, even other floor pedals. With these control options already available, I would be very surprised to see Singular Sound release different product versions with the same functionality but different form factors. And I certainly wouldn’t want to have to buy 3 different units for floor, mic and table top.
