The SEQ is a host synced 8 step voltage array that can be routed to Osc1, Osc2, Oscs 1&2, The Filter, The RM freq, or the Dist Freq. Think of it as another LFO type Modulation source with nil CPU hit. The little blue slider controls the overall level and the 8 rotary knobs control the levels of each step.
The TUBE is a tuned delay line that causes a form of harmonic distortion. The Offset control tunes it from 3 octaves down to a pitch matching the main oscillators. The scream control affects the feedback or intensity of the control. The smooth control rolls off some of the highest frequencies, sort of mellows the sound. The AMT control determines how much of the effect is mixed into the rest of the audio chain.
Karnage is still free and available as a VSTi for Windows.
