Hi Joshua,

Thank you for your comment, you will need to make sure the USB lead you are using is a USB Data cable, and also check your browsers are updated to support Midi, please use the link below to help with this,

100% the issue was I was using a USB lead not rated for data... SMH something so stupid. Thank you so much for the response and everything is updated and running perfectly. - Joshua Brown 17 Apr 2020 at 09:49 PM
How do I know if it's a USB for data? This is what I just ordered, will it work?
