Keywitches being notated after reopening project

I have an issue where when I reopen a project, and start inputting notes, the keyswitches are being scored in an odd manner on the next beat, doubling up the note I input; example here:-

I think this occurs because the init is not being applied until I press play on the transport?

Can you attach your project, or a cut-down version that would allow us to reproduce the problem?

Sure - here it is.

Thanks for attaching the project. I’ve had a look at the expression maps and everything looks in order. I tried inputting some notes via my MIDI keyboard and am unable to reproduce the problem.

No worries; thanks for taking a look. I’ll see if it happens again when I restart tomorrow etc.
