Sound player with positional markers

[gunther]

Hi,

for those who might need a sound player with positional marker points, I enclose a working test patch.

for my latest project I pimped up the sound player actor with Javascript in order to allow jumps to markers and allow a positional slider (like other players as vlc). My new project is completely driven by audio positions of one piece of music. The marker positions drive the whole setting of video and light changes. 

For setup and rehearsal I need to jump to specific positions in the music. So I designed the marker actor to jump to the exact position, and also to jump to the position 2 seconds before the marked position.

For testing purpose I extracted the relevant parts of the patch and added simple projections as proof of concept. Just use an audio file of your flavor and have fun with test sound player advance .
