Generate score - MIDI Files?
The
"Generate score" item of the "Edit" menu has
the purpose to compute the score according to the composition
blocks of Pizzicato. It was never expected to be used to
transcribe a MIDI file into a score even if, in version 2, in
most cases, it was acting like this. Version 3 is slightly
different and it does not work for that purpose. To import a MIDI
file and display the score, you should use the File, Import MIDI
file... menu. Then select all measure (Edit, Select all) and
transcribe (Edit, Transcribe).
