Call me eccentric, but I have always disliked the midi hardware interface.
It is essentially event-driven, and if for any reason one event is corrupted or missed, you get ciphers (notes stuck on).
I've always scanned keyboards directly from the host computer, and recently I needed to upgrade to a USB design. If any fellow hobbyist is interested I have put propaganda and details on a corner of my website at http://WWW.chateau-rentals.com/Organ
Although the interface was selfishly designed for my own circa 2000 VPO software, I have the ability to make the console appear to 3rd party software as a multi channel midi input, so aliens like Hauptwerk can run with it too. The whole console is scanned every 2 ms , so there's no traffic jam even with the most demanding music. I'd welcome any comments.
Hi
Trevor Hawkins (EOCS member) has been doing this sort of thing for many years. It might be worth getting in touch with him - if only to compare notes.
Every Blessing

Thanks - I will follow up.
