I have the latest version of Reason Suite 11 updated.
I point out that the anomaly concerns the drag and drop of a midi file.
If it is imported with the appropriate "Import midi" function from the menu it works regularly.
But when you want to drag the midi file into the sequencer to any synth from the finder (in my case I use Mac) the bar
with the notes will be truncated by inserting only a couple of measures that is "2 quatrains".
In practice, the sequence of notes, or the possible chord is incomplete.
I have tried with several midi files and the result is always the same no matter how long the midi file is.
Are you aware of the bug in question?
