Triggering more than one macro at the same time

I like to have hotkey triggers send midi messages. However, I can only send one hotkey trigger at a time.. when I try to press two hotkey triggers at the same time, only one of them ends up going through. I assume this is a limitation of the OS, but does anyone know if it's possible to trigger multiple hotkeys at the same time, even if they are microseconds afterwards or before?

Dup post. Thread closed.
