Mr. Original Poster, Yes, the sliders serve multiple purposes. Note - the writing above each of them...they line up. These sliders serve as faders for how loud each of the different LAYERS [that make up one sound] are. The top row is the Solo Synth (i.e. Synth1, Synth2, PCM1, PCM2, ect..). Second row is the Hex Layer (i.e. Layer1, Layer2, Layer3, Layer, ect..). Third row is Drawbar Organ (i.e. 16', 5 1/3', 8', 4', ect..). As everyone else has stated, it requires a little time to get used to the architecture. It's a very DEEP and POWERFUL synthesizer. This may seem like a headache, but if you were to say, try Kurzweil's Virtual Analog VAST, you may get an aneurism. Here's a video I highly recommend you watch: https://www.youtube.com/watch?v=a3-XLtgVVDo. It may seem hopeless now, but you'll eventually get it, trust me.
