Thanks for creating this library. I'm just trying to get started with it and I keep getting this error when trying to connect. Can you give me some direction? Thanks.

You're probably using the wrong midi port(s). The Midi port your launchpad is on varies per machine and setup. If you're on windows, the windows keyboard may be your first MIDI input device. Try the values (0, 0) and (1, 0) and see if that works. :)

Spot on, @JeromSar!

It looks like that'll be your issue, but if that doesn't fix it feel free to let me know and I'll reopen the issue.

Happy Holidays!
