levels sound great on my good headphones ^^ try playing around with chorus, high passing and triangle waves to add some girth to your pads too, and/or layering it with a slowed down 1/2 rasslebocked pad.. just run a wire from your effects into one of the outputs on the rasslebock (not the last one) make sure to highlight the output pattern on the rassle and control the wet/dryness of the 1/2 effect you add ^^
Ahhh I thought the big synth might have a few problems but I don't have my good speakers right now so I couldn't tell, I'll republish it sometime though!
