100% agree. This is why e.g. the A-189-1 bit modifier does not have the LCD
and menu buttons of the first prototype shown at NAMM 2007.

That's exactly what we did. We have two "cores" (small adapter boards): one
with a large memory (for anything that has to do with CV or audio delay) and
another one for immediate signal processing/calculation without the need of
a memory. But for the bit modifier A-189-1 we found that it's cheaper not to
use the additional board but to put the microcontroller directly to the main
pc board.
