Hi I am using a rane ttm 56s mixer with sl1 scratch live. i have shitty little sony stereo with one input that the mixer goes into. i can play mp3 files through serato. however, i cannot play swf files through the speakers because they are not compatible with serato. is there any good (free)converters from swf to mp3 - alternatively, is there a way they can be used with serato? as my stereo as one input i cant put the macbook through it as the one input is being used by the mixer hope this makes sense any help much appre
