My apologies if this is already here somewhere, but while doing a search for the EWPro, I ran across the Sandbox web page:
They apparently designed the enclosure for the EWPro. Here are a few pix I snagged:
Some of the early concept pix look rather like the Theremini.
It's pretty, but I'm not a huge fan of the EWPro design. The controls seem poorly angled, particularly the lowest ones. Style is fine, in its place, but it often displaces function, something the style guys seem fairly oblivious to.
A lot of what attracts me to technical products, particularly musical ones, is in how well the form enables the functionality.
The vertical configuration of the EWPro guts, with the power supply located in the base and the vent at the top, seems like it places the sensitive oscillators at the top of a heat chimney?
