Well, I did check on my end -

But I don't get ANY bogus notes where I record in 4/4.

The only bogus notes are from trying to record a waltz.

Actually, why are some of the durations 65535 ticks long?

And why wouldn't it ignore or reject notes of ZERO duration?

Anyway, if there was a problem on my end, wouldn't I see it no matter what the time signature is?

When I record the melody, it tells me that there are less than 50 notes recorded, far less than the MIDI output shows (in 3/4 time).
