Wave Runner is a multi-waveform sync-able LFO based on the Electric Druid TAPLFO2D family of code, but with some significant additions and improvements. The TAPLFO2D-FC PIC and code is exclusive to Frequency Central and was developed specifically for the Wave Runner, and is not compatible with similar modules.All waveforms can be skewed using the Distort knob, as well as control over pulse width of square, and distortion of the cyclic waveforms, this get you control over Noise freq as well as bitcrushing, bitcrush of S/H down to 1 bit for random triggers. Tap sync input, for syncing to whatever. Wave Runner measures the last two incoming pulses and syncs itself to these. Multiply knob allows for Wave Runner to run at x0.5, x1, x1.5, x2, x3 and x4 of the incoming sync pulse. Freq is from stupid slow (0.025Hz) into low audio range (50Hz). The latest version also features Level CV input to control the absolute output level of the LFO.Features:8 Waveforms available• sawtooth• ramp• pulse• triangle• sine• noise• sample and hold• stepped triangle / sawtooth / rampDIY-Kit-Type:THT-Kit-1.

GITGUD is a pack of 9 individual LFOs - 5 squares and 4 triangle waves.The frequency is set with analog touch controls; they act like potentiometers and they keep the value once the finger is lifted from the surface.As it takes time to turn a pot, it takes time to interact with these controls:bridge with your finger the first line and the center to decrease the frequency or the center and the last one to increment. A red and a blue LEDs will light up to give visual feedback of the speed of that LFO. This is a full analogue continuous control, designed to be an expressive and interactive gateway to decrease the boundaries between the user, the environment and the music-making-devices.Features:• 9 individual analog touch LFOs with toggle switches to chain them.• Individual touch potentiometers to set their rate.• Frequency range from 0.25 Hz - 15 BPM to 20 Hz - 1.200 BPM.• Single board design - extremely skiff friendly.• “Whatever” power connector a.k.a. don’t mind the polarity.

The MSK 010's Wien-bridge oscillator cores produce low-frequency sine waves natively, in a fully analog way with a minimum of harmonic distortion. There are no glitches from waveshaping or stair-steps from insufficiently filtered digital-to-analog conversion. Modulate synthesis parameters with these for smoothly evolving timbres and mind-expanding soundscapes. Because the cores are fully independent and will not synchronize, a patch using multiple LFOs will not repeat its modulation state for a long time, if ever.Choose one of three variants of this module, each with its own set of eight nominal frequencies and cycle times. There are no duplicate or near-duplicate frequencies between different variants, so with two or three, you get the full benefit of a larger modulation palette. Note that the nominal frequencies are just that; every module will have its own one-of-a-kind pattern of exact output frequencies within a few percent of the nominal values, due to component tolerances.• Variant A - 16mHz, 60mHz, 190mHz, 410mHz, 720mHz, 1.3Hz, 4.8Hz, 16Hz (63s cycle time down to 63ms)• Variant B - 34mHz, 88mHz, 160mHz, 280mHz, 600mHz, 1.8Hz, 3.4Hz, 11Hz (30s cycle time down to 94ms)• Variant C - 28mHz, 72mHz, 130mHz, 340mHz, 2.2Hz, 4.1Hz, 7.2Hz, 8.8Hz (35s cycle time down to 110ms)Features:• All-new design, not a clone or imitation of anything else• Fast starting - full amplitude oscillations within one cycle of power-up, unlike the usual behaviour of an oscillating filter• Through-hole design for easy hand construction and maintenance• Connectors between boards, and panel components, mounted on the boards; no flying wires• All three variants build from the same bill of materials; one full kit or PCB set can be used to build any one variant of your choice.• No compromises on build quality: real aluminum panel, not PCB material, with colour printing; nickel and gold plating on the circuit boards; close-tolerance fixed resistors and integration capacitors.• Complete technical documentation released under GPLDIY-Kit-Type:THT-Kit-1.

In a simplistic way, The Mod Medusa could be described as an Euclidean LFO: an “algorithmic” modulation source which produces variable period LFO signals synced to rhythmic patterns. Those patterns are generated by algorithms such as the Euclidean one or different ones coming from the White and Knight's Gallop. The Mod Medusa has 4 outputs generating 4 correlated LFOs, which give different “polyrhythms” according to the chosen mode. Generated waveforms can easily be twisted using the symmetry and shape parameters which continuously morph the signal into different waveshapes. Many on-panel controls, assignable Gate and VCA Inputs turn the Mod Medusa into a strong performance tool. A very unique approach which leads to instantaneous and original results.Features:• Unique concept of sequenced LFO• Four outputs which can be correlated or independent• Four correlation modes: Main, Compute, Random or Phase• Eight tables generated by algorithms producing different rhythmic patterns• Length (from 1 to 16 steps), density and shift controls over the sequence• Shape and symmetry controls over the generated waveforms• Unipolar or Bipolar outputs• Peak Sync function allowing to synchronize the LFO differently to the incoming clock• Assignable gate input which can work as ratchet, track and hold or one shot mode.• Assignable VCA input which can be assigned to any output.• On board clock divider• Bipolar CV inputs (except for the VCA input)• Current state storingDIY-Kit-Type:SMD-Kit-1.

Mal-2 is a random signal generator mainly intended as CV modulation source. It has 2 modes of operation to provide you with smooth random goodness. Imagine Eris herself lends you a third hand to keep your patches interesting.In the first mode the CHANGE knob morphs from a cubic interpolated (sine like shaped) random signal to a random walk function that could make a wallstreet broker delirious with joy.In the second mode the CHANGE knob sets the self similarity. On the minimum setting the signal is completely random. On the maximum setting the random sequence is locked to a repeating, identical 8 step sequence. In between the sequence seamlessly morphs to new shapes over time.This gives you a random CV where you can shape the bounds in which the chaos unfolds and goes far beyond a slew limited white noise.DIY-Kit-Type:THT-Kit-1.
