The design of these velocity sensitive buttons amazed me! It is such a brilliant idea! This isomorphic keyboard has a total of 192 velocity sensitive keys. There are two PCBs, one above the other. The top PCB has Cherry keys like those used in keyboards. The bottom PCB has simple tactile switches. The buttons on the top PCB have a shaft in the middle, and when the key is pressed, this shaft presses also the tactile switch that lays under the button. There is a small delay, from the time that the button is pressed until the tactile button is pressed. The shorter this delay is, the faster the button is pressed! Such an amazing idea!
I've been looking at similar ideas pertaining to velocity sensitive input...I realize this page is two years old, but I found it and I wanted to say something. The new touch screen technology have been able to include vibrato into input but I still haven't seen it with velocity sensitivity(ex. tachyon). Do you have any ideas on how to get the touch screen technology velocity sensitive without having padded zones under the screen? What I'm interested in is programming velocity sensitive zones relative to impacts enabling correction to human error in playing and maintaining the vibrato function, as well as the dynamic synthe with vertical scrolling.
