Thanks everyone for your kind comments:
@Jennifer.. The tone arm is separate from the base of the turntable and is a dial on the same layer as the spinning record. There are triggers which add a little bit to the dials variable at different times on the timeline which moves the tonearm in an arc on the record. As the timeline of the layer is repeated with the go to time trigger it just keeps adding to the variable until it reaches the centre. If you are interested I'm happy to share the storyline file with you.
@Ron... The music is an mp3 that I mixed with an mp3 of the sound of a needle in the grove with no music giving it that record sound. You can hear the beginning and some static pops as it goes through. If you let it get to the end you can here the tick tick tick of the needle at the end of the record. I did think of using more songs.(it's an LP after all) and being able to play different songs by moving the needle. But hey, I'm supposed to be doing my compliance training ;)
