Jerry ,
"I love accordions, but an acoustic accordion will never have the sonic varieties and possibilities."
This reminds me of a parallel development in domestic sewing machines.
Originally, domestic sewing machines offered only a straight stitch.
With time, elaborations were added (button hole stitch, zigzag stitch, etc)
Eventually, the sewing machines become so elaborate that, having programmed quite a complicated pattern of embroidery, the operator could sit back with a cup of tea and biscuits, while the machine got on with the job.
The problem was, not all owners could cope mentally with their manuals, the programming, even the increased weight of the machines themselves.
Consequently, many of these you beaut testimonials to technical ingenuity often remained unused, on the shelf, their owners bitterly lamenting the loss of their old user-friendly predecessors ?
There's now quite a demand for quality ( eg the Elna Lotus ), simple to use second hand sewing machines.?
