Our apologies for the late response to your question. I would recommend that you contact Dancing Dots, a company that has a software program called GOODFEEL. This music braille translation program is quite adept at transcribing basic music notation but I can not speak to whether or not it will correctly annotate drum music or chord symbols. William McCann, the owner of the company is also the engineer who wrote the software program so he is very knowledgeable and could answer your question more specifically. go to dancing dots.com for more information.
