Interesting point of view. I wouldn't consider that the above mentioned site is a competitor with Ultrasabers seeing as how they do not sell sabers, hilts, or electronics. And Ultrasabers does not sell sound fonts. Oh, and they're mentioned in a lot of places here on the forums. Not to mention that one of the biggest contributors over there is Novastar - some of whose sound fonts are on the forums here and Blackstar and Ancient Saber even came pre-installed on my Diamond.
They do work on the Obsidian v3 and v4, as well as the Diamond. A little conversion is neccessary - using MediaHuman does the trick - as mentioned here:
http://www.saberforum.com/index.php?topic=37244.msg604780#msg604780I've actually tried several from there and most of them work and sound great, I was just wondering which of the "optimized for" worked best or if it doesn't make a difference.
EDIT:
And after re-reading the post above I found my answer, LOL. But to be honest, I found the Youtube video long before I ever even looked at the post here.
