Introduction The Mod Medusa is an algorhythmic LFO. It delivers four correlated or independent modulation channels synced to a clock. Their timing fits rhythmic patterns, such as euclidean ones famously used in trigger sequencing. You won't run out of modulation waveforms anytime soon, as the Mod Medusa has symmetry and waveshape controls.
Turned clockwise, the sequencer generates more and more triggers per cycle. But Mod Medusa is not a trigger generator, so what is different? In the case of our algorhythmic LFO, simply replace the word trigger with waveform cycle, and you get the kind of modulation presented in Fig.

Clock the module by inserting a clock signal into the clock input or by tapping the tap button [B]. Like a classic Euclidean sequen- cer, the Mod Medusa gives several controls on the source pattern: Length [D], Density [G], and Shift [I&J].

Polarity & Peak Sync The uni button switches between unipolar (0 – 5V) and bipolar (- 5/ +5V) LFOs. In unipolar mode, the button is lit. When the Peak Sync function is off, the beginnings of the waves are synced to the incoming clock signal. Activating it synchronizes the peaks of the waves to the clock signal.

Press the Mode button for two seconds. A mode LED starts blinking, indicating which channel is edited. Use the Mode button to switch between channels. Use the controls to set the channel parameters. Press the Mode button for two seconds to exit. In independent mode, CV inputs only act on channel 1.

When assigned to Track & Hold, the outputs track the LFO cycles normally while the incoming gate is high, and hold their value when the gate is low. Using triggers instead of gates will give a Sample & Hold feeling, better suited to create stepped values. When assigned to One-Shot, the LFO cycles will only start when a gate is received at the beginning of the cycle.
