The point of the wired Hot Hand is to check it out and see what is possible. We have some extra ones, so I thought some of you might like to check it out at no cost. The wireless one is NOT a toy. We have sold more than 10,000 of them to all kinds of very serious bass and guitar players. I would guess the ratio is 2 to 1 bass players over guitar. Hammering notes and shaping the filter is the most common application. Nathan Navarro got famous using Hot Hand on bass. Almost 14M views.
Sorry if I struck a nerve there. It's just my opinion on it's application. I can see that one application that would be nice if it can be done would be to use it for vabrato. Instead of bending the string, you could just wave your hand but I would like to do that on a tone that sounds like bass. Since it needs to effect an envelope, filter, or some other effect engine, it might not be possible.
I watched the video. I guess in that particular song what he is doing works. I play a lot of funk, jazz, and rock. I was trying to incorporate in some funk bass last night using the Hi Funk preset that is in the cloud and couldn't get it to work. I was hoping it would retrigger the envelope. I probably need to play with x and y axis more to get it to do that. The one it worked best on was called Magic which was someones take on the synthesizer solo in the Heart song Magic man. I got a similar effect to what Nathan was doing.
