Let's take a closer look. We have eight true analog monophonic synths here, logically thought of the same way we'd think of channels on a mixer, except that each synth, or channel, is laid out horizontally on the front panel rather than vertically. The synths have different controls according to their purpose. You can get dead-accurate renditions of those sounds, but the DRM 1 is capable of far more adventurous and interesting sounds. Drum 2 is making a wobbly ascending sound, and Drum 3 is making a ring-moddy descending sound.
Attack adds a clicky transient to the sound.
FM Intensity and Frequency control an LFO tied to Pitch. With certain Bend settings, FM Intensity and Frequency can be dialed up to give a cool heterodyning sound that resembles ring modulation. A touch of this effect adds great character to a kick drum sound. The Distortion control adds a lot of attitude and harmonics, and can fry the tone pretty crisp. Its internal distortion can be rude, to be sure, but it won't get truly ugly.
