There’s an issue with recording MIDI. The first note never immediately sounds when you hit it. It’s like the engine has to be prepped.
For example, if I want to record a new part, I have to hit a couple of notes before the part where I intend to play, what I want to use, so that first note will sound as soon as I press the key and not sound late and throw the timing off,
This is certain a bug of some kind.
