Modules for Voltage Modular


Slo Fo

Meet Slo Fo. The very, very, very, very slow LFO.

Ever needed to gradually open a filter across your full 15 hour remix of Wagner's Der Ring des Nibelungen?

Ever wanted to morph between 4 different soundscapes across several minutes, or even hours?

Do you wish you had an LFO so slow that you can't stay awake long enough to see it repeat?

Slo Fo has you covered.

Purpose

Slo Fo has five different waveforms and caters for time periods from 0.1 seconds to a ridiculous 24 hours across three frequency ranges.

Features include 4 quadrature outputs, adjustable output amplitude, some quick set buttons for common voltage ranges and a nifty means to enter an exact frequency or time period.

Inputs

Reset

A standard trigger input. A rising edge will reset the waveform to the start. 

Outputs

Quadrature outputs

These four outputs provide the waveform in four different phases, each 90 degrees shifted from the previous one. 

Controls

Frequency knob

This sets the output frequency using the range selected with the range switch.

The tooltip shows both the frequency and the time period and a nice feature is that you can right-click, choose "Edit Value" and enter an exact value as a frequency in Hz, mHz or uHz or as a time period in s, m or h.

Range switch

This selects one of three ranges.

High range goes from a scarily quick 10 Hz down to 0.0167 Hz (or 60 seconds in more useful units). 

Medium range is 60 seconds to 60 minutes.

Low range is 60 minutes to an utterly daft 24 hours, that's 11.57 microHertz in case you were wondering.

Waveform knob

This selects one of five waveforms: sine, square, triangle, sawtooth or ramp.

High and Low range knobs

These set the level of the output between -10v and +10v.

Quick Set buttons

These buttons give you a quick way to select common output ranges, 4 unipolar and 4 bipolar.

Reset button

This resets the waveform to the start.
