Midi import dropping notes and mangling others

[dascott]

I have a flute trio created in Logic Pro, exported as MIDI, and imported into Dorico with quantization set to 64ths. Here are some of the opening bars from the Logic version:

and here is what I get in Dorico:

The “double stop” is a grace note I have to fix - but what happened in the two 3/8 bars? I have tried different quantization settings, but nothing explains the doubling. Thanks!

It definitely seems to be linked to the tuplet recognition in Dorico. Did you have a look at the way Logic shows the midi notes in the piano role for the bar with the tuplet in. If there are overlaps between the notes that often causes weird export and related imput issues.
