Using ch := in.Listen() seems to lose data

Hi

I seem to have an issue using in.Listen(). It loses key presses. Often I can press just one key, but only see the key down event, not the key up.

Have you seen this behavior?

Thanks
Dan

Interesting, I'm able to read both up/down events. I even have another library using portmidi and has an if condition to filter out to down events: https://github.com/rakyll/launchpad/blob/master/launchpad.go#L85

Same issue. Totally not working in my case: KORG KRONOS X or KORG nanoPAD2.
