re sensor keyboard, seems to me if it's rackmounted, adjustable
rack ears would be most advantageous for everyone, especially
considering the nonstandard shape of such a device as this.
something as simple as removable ears and multiple mounting
holes (on the side of the unit) which would allow mounting the
unit at different angles/depths within a rack would kill several
birds w one stone. this simple idea has worked very well with
sherman's unusually-shaped filterbank. it lets the user decide
what works best.
