Haven't found a simple circuit that generates a sequence of 8 voltages controllable by individual knobs. MK's 5-step sequencer, expanded to 8 (or 10?) Breadboard MK's 5-note to 8-note. Expanding out to 8 (or 10?) Breadboard MK's 5-note sequencer. Compare to online 8-note schematic, or extend MK's 5-note sequencer.
