A simple circuit that generates a sequence of 8 voltages controllable by individual knobs. MK's 5-step sequencer, expanded to 8 notes means ~$16-20 in parts, two tl074 op amps and otherwise a bunch of wires backwards Fix floating pin for op amp Fix floating pin for op amp in schmidt inverter mode, maybe both 7808 and hex inverter trigger are unnecessary? Alternative: Midi -> CV Alternative: CV from something else VCF MK's Diode Ladder VCF ~$8 in parts, depending mainly on whether 8+6 pins + hardware fits on shaek board or similar size perf. MiniADSR derived from ICU project. See icu-license.html for license of the knob.

BSD: H H H H H MS2: R R <- higher MSD, usually just one mallet; can play a lot of wiring and increases risk of noise on power rails. Things best left to external modules: - CV-controlled CV offset module - add a voltage to another voltage.
