The most obvious application to my eye is adding the ability to incorporate real cymbals in a kit, while preserving the ability to reproduce the performance via MIDI. Put a trigger on the cymbal to record MIDI, and one of those striker dongles on there to play it back. It seems to offer the potential to have a hybrid kit without losing the ability to edit things.
Very interesting.
Product is not to market yet, and the expected price is $800 USD and $200 USD for each additional ball. If I read all that right, it ends up being $1200 for 3 of these and I would need three sets of $1200 plus some way of actuating a hi-hat stand to do what I just had in mind.
Allllrighty then. I'll be taking a pass on all that. Maybe in 20 years when it gets cheap.
