Warnings in “Add New Post”

Hello,
I am using this plugin for commercial use, and i have noticed some warnings in Debug Bar after enabling debug mode, this error is in “save_post_data” Function on soundy.php line num 1199 on plugin at this time, its generating 12 Errors on Add New post page, at the WordPress back-end, Error describes that undefined index “post_type” in line num 1205, i can fix this with using if isset conditions, but because i am using this plugin for commercial use, i have to use it directly via WordPress repo, so please if you guys can fix it, i have tested this plugin with if isset conditions, its not generating any errors and also working normally as you guys provided, hope you guys can fix it soon, if i can make any contribute with my codes than i will be glad to help you, thank you.
