Firmware 1.17 offers:
* User editable input scaling to match sources that don't generate perfect 1V per octave signals.
* Complete rewrite of the main processing with higher precision.
* ... and the unavoidable fixes and tweaks ;-)

The updated user manual 1.4 is much expanded with operations described in exquisite details :-)
.. and a version 1.5 corrects a mistake in the input calibration description and eases the reading elsewhere.
