Full Description

4-Channel Pingable LFOS

The 4ms Quad Pingable LFO is one of the most versatile LFO-based Eurorack modules available on the market. It features 4 channels in total, with each featuring its own independent LFO. The waveshapes available are comprised of Pluck, Ramp-Down, Triangle, Ramp Up and everything in between. Each of the channels provide extensive modulation control, as well as the ability to trigger and reset each other for complex and morphing outputs. This highly compact module retains its power and versatility with a wide range of useful functions. One of those functions is the integrated tap-tempo control, allowing you to manually enter the tempo you require when creating your sounds.

Versatile Modulation Control

This module is a sound designer's dream, providing more than enough features to ensure you can create a wide range of tones and sounds. The versatile controls provide a variable speed, starting all the way at 71 minutes with the fastest speed rates at around 500Hz, as well as marginal tracking up to 1kHz. The tap temp button is free running, acting as the ‘Ping’. The Ping jack allows you to set the tempo with an external clock for optimal flexibility. A skew knob and CV jack allow you to control the waveshape via altering the ratio between rise and fall times. The Reset jack is also useful for restarting the LFO, without affecting the tempo. The clock-syncable LOF and variable skew and reset controls make it easier than ever to create a wide range of premium-grade sounds and tones.

Advanced Functionality

The compact design and wide range of features and functions allows you to get in-depth with your sound design. For example, you can use the module as a Bipolar/Unipolar jumper, setting the jumper to change the voltage of the outputs, with a single jumper control for all four channels. One of the most unique features is the one-shot mode which allows you to use the Reset jack to trigger a one-shot envelope, when the external ping clock is not in use. A Floating Reset mode is also included, giving the waveshapes the ability to run freely without re-syncing to the ping clock. The outputs on the module can be connected to other 4ms modules such as the VCA Matric and SISM.

Features

• Quad "pingable" LFO's -- frequency is set by time between pulses ("ping")
• Each of the 4 channels is an independent LFO
• Can produce a variety of waveshapes: "Pluck," to ramp-down, to triangle, to ramp-up, and all shapes in between
• Channels can easily modulate, trigger, and reset each other for complex and slowly morphing outputs
• Slowest period is about 71 minutes (0.0002 Hz), fastest speed is about 500Hz (marginal tracking up to 1kHz)
• Tap tempo button is free-running (LFO runs indefinitely), but external clock/Ping is auto-stopping (LFO stops when external clock stops)
• Tap tempo button ("Ping") for manually setting the tempo
• Ping jack sets tempo with an external clock (any complex signal can be used as a clock)
• On/mute button enables or mutes the output (latching button)
• Skew knob and CV jack control the waveshape by altering the ratio between rise and fall times
