SoundForce Dual LFO Module (12HP)

Full Description

Tempo-synced goodness

For both channels of the Dual LFO, you can toggle between free-running operation or tap/sync LFO operation. In free-running mode, Dual LFO offers manual control over the Division/Frequency of your LFO signal, with three frequency ranges available to choose from using the H/M/L switch. The time divisions are; H: 30Hz to 500Hz – M: 1Hz to 100Hz – L: 1min to 10Hz.

In the tap/sync mode, the frequency of the LFO is matched to the frequency of the incoming signal that's patched to your TAP input. Using the DIV/FREQ pot, Dual LFO allows you to multiply or divide the clock frequency manually. Normalled inputs mean that both channels of the LFO will be dependent on the incoming clock signal. This allows you to internally modulate the LFO when in tempo-synced mode. For example, you can modulate the division of channel 1 with a random voltage from channel 2. Using the Tap mode, you can use a sequence to control the tempo of your LFO. In the ramped down waveform setting, this can sound much like an envelope generator with a fast attack and quick release.

Explore eight waveform types

Key to creating the signature sound of your LFO is the waveform. With Dual LFO, there are eight to choose from, offering a wide range of styles and tones to unlock within your patches. Among the more traditional sine wave, square, pulse and triangle, Dual LFO includes exciting and more unique waveshapes such as stepped triangle, random, and rising/falling sawtooth. Each waveform offers a distinctive shape that will influence the response of your LFO either in synced or free mode. The included wave CV inputs and attenuverters offer flexible modulation between the waveforms using external signals. Ideal for integrating into your existing system, the attenuverters can send the signal into both negative and positive, allowing for diverse modulation and control through other Eurorack modules.

Most interestingly, the Random waveform extends more functionality than other LFO modules. Effectively the same as a noise signal being sent through a sample and hold circuit, the Random waveform can be used for so much more than just a waveform. In free mode, a new random voltage level will be sent to the output jacks at the frequency of the LFO. The result is an exciting stream of random voltages at lower frequencies with high-frequency noise introduced simultaneously. In tap/sync mode and with D/F on 1, a new random voltage is sent to the output every time a trigger is received on the TAP input signal. By adjusting the D/F position either manually or via CV control through the attenuverter, random voltages can be sent between triggers with cascading multiplying ratios.

Features

• Two modes of operation for LFO including Tap/Sync and Free
• Tap mode automatically sets the LFO speed based on the incoming signal to the tap input
• Free mode allows you to change the position of the DIV/FREQ pot to apply modulation to the LFO freely
• CV input attenuverters offer flexible modulation
• Normalled Tap inputs allow you to combine both channels simultaneously, using both synced and free modes on different channels simultaneously
• It's possible to select your waveform via CV attenuversion
• Second CV input acts as a Frequency Modulation, changing the speed, similar to an FM input on traditional synthesizers
• In synced mode, the second CV switches between different dividers and multiplication and the intensity can be controlled using the attenuverters
• Eight waves per LFO including stepped triangle and stepped random for more advanced sound design
• Unlock noise/random waveforms when in Free mode for an even greater range of tonal variation
• Dedicated knob per LFO to control the speed which functions as a control for the divider and multiplier when in tapped mode
• Three speed settings for the speed of the LFO can be used at audio rate
• Highly flexible and powerful module packed into compact 12HP rack
• Dual outputs can be used simultaneously to send your signal to different destinations
• Bipolar and unipolar outputs available
• Cross modulation capabilities allow you to modulate itself, creating expansive evolving tones
• Powered by STM32 microcontroller with ADC and DAC built-in
