With the recent update of Mountain Lion, I am no longer able to play embedded midi in browser Safari, and do not foresee Apple will provide solution in the near future.
After some searching, I came to your product Jazz-Plugin, but I am a bit confused how to use Jazz-Plugin to solve my problem. The website that I listen to the midi is this link http://www.duosuccess.com/tcm/001a01080301b01aj.htm.
Does the website need to re-code the web page ? If so, could you please help to suggest the correct syntax ?
