Clocking & modulation utilities: LFOs, clocks, S&H, slew

The whole task here is the connective tissue of any live modular or groovebox set: a single tempo source that every moving part obeys, and a modulation network that keeps a patch alive without your hands on it. In techno and ambient performance alike, this is what separates a static loop from a patch that evolves for a minute on its own — clock discipline plus animated control signals.

The arc starts supported. First, get one master clock running and understand why every time-based module hangs off it (“A master clock sends pulse streams that synchronize all time-based modules”), then derive slower and faster phase-locked streams with dividers and multipliers — drill this until pulling a /4 or x2 line is reflexive. Next, build the modulation side: patch noise into a sample-and-hold clocked from one of your divided streams (drill the S&H-from-noise patch too), smooth its staircase with a slew limiter, and route an LFO to multiple destinations. The LFO atoms here describe menu-driven trig modes (FRE/TRG/HLD/ONE/HLF) in the Digitakt II architecture, but the underlying concepts map directly to modular: free-running, trig-reset, and held-on-trig LFO behaviours are available in most Eurorack LFO modules and translate patch-for-patch. Splitting one source three ways is where the buffered-vs-passive multiple distinction stops being trivia and starts gating your patch.

The capstone removes the scaffolding: one clock, divided and multiplied streams, an LFO and an S&H source animating at least three destinations via multiples, recorded for a minute. Every required atom is something the capstone cannot be done well without. The supporting set enriches from there — adding jitter for humanized timing, quantizing your random CV into melody, Perlin-style smooth randomness, logic gates and rest-trigger accents for conditional rhythm, a DIY passive mixer, and macro-knob mappings for performance — each a natural next step once the core network holds together.
