yeah the rs9 will go first - you take trigs out of RS-9 from one of the tracks and then patch into the TRIG IN of the 182. This way your melodies will have rhythm to it instead of just advancing one step sequentially based on just starting the sequencer on its own. You will get some nice melodies. Program 7 trigs on the RS9 over a bar and use a 5 step sequence in the 182 to get you starte and you will hear an eveloving melody.
