The experiment conducted yesterday revealed a situation in which Midi Note Number could not handle the high frequency side, and it was decided to reconsider the structure of the Pitch side detector.

The problems occurred from narrow dynamic range was solved by removing its limitation, then expanding the range of the values handled to 16 bits.

And replace the data type of the offsets from unsigned to signed to expand the range of pitch that can be handled.

In addition, the root note of the tuner, which had been set incorrectly,

was rewrited to the correct value,

and the discrepancy that had occurred when judging pitches was corrected.
