The SoundForce Chorus 6 is a robust module paying homage to the classic Juno-style BBD chorus while incorporating modern features that elevate its potential. This 16HP eurorack chassis makes generous use of CV inputs and deploys the Xvive MN3009 in its journey of reviving the vintage, ‘sweet and pretty’ Juno soundscape. Outstandingly, it provides more innovative features like the manual and external modes allowing for a deeper, unorthodox exploration of sound that moves away from convention.
The essence of a chorus effect lies in the amalgamation of a dry sound with a modulated delay of the original signal. In the Chorus 6, this modulation is at the behest of an LFO, thus weaving in an arresting dynamism into the sound. With the LFO modulating signals on both the left and right channels differently (180 degrees out of phase), an expansive stereo environment is crafted. This is strikingly identical to the chorus in the Juno models.
The profound nature of the effects delivered by Chorus 6 is intricately tied to the delay generated by the MN3009 BBD chips. Alongside this, there are pre and post BBD filters that brilliantly mask any inevitable artefacts resulting from the utilization of BBD chips. This combination generates a sound output that marries the vintage charm of the Juno Chorus with a contemporary feel.
Unboxing the mechanics further, the STM32 micro-controller emerges as a core player in getting the audio to navigate through the MOSFET chain in the BBDs. This deviation from the erstwhile MN3101 BBD driver chip introduces a touch of modernity, further enhanced by the tactile switch-based digital interface that reflects in the appearance too.
The SoundForce Chorus 6 steadily affirms its unique presence, offering four primary modes: I, II, I+II, MAN for manual and EXT for external. These modes expertly echo the synonymous relationships between the Juno 6/60/106 and the Juno-style soundscape.
In manual mode, the Chorus 6 goes over and above, facilitating absolute control over the intricacies of the chorus. Here, features such as the time slide pot, the rate slide pot and CV input, the depth slide pot and CV input, the mix slide pot and CV input, the LFO wave, and the range parameter duly enrich the existing modulation vitae.
The Chorus 6 features stereo inputs, offering ingenious solutions for enhancing mono signals and perfecting stereo ones. The module is accommodating of both Eurorack and Line level signals, hence displaying inclusivity as an integral aspect of its design.
With detailed deliverables and an engaging mechanism, the SoundForce Chorus 6 is an enticing eurorack module that skilfully blends the old with the new, delivering a powerful Juno-style soundscape. Its distinctive features like the full delay range of the MN3009, the 100% analog, VCA-based crossfader mix control, and accommodating Eurorack and Line input levels stand out, asserting its rightful place in your Eurorack setup.
Novice-level usage example:
Once you have installed the SoundForce Chorus 6 module in your Eurorack setup, let's start with a basic usage scenario. In this example, we will use a mono audio source such as a synthesizer or drum machine to experience the classic Juno-style chorus effect.
- Connect your mono audio source to the left input jack of the Chorus 6 module.
- Adjust the input level using the input level switch located between the module's PCBs. Set it to Euro if you are using a Eurorack level signal.
- Connect the output of the Chorus 6 module to your audio interface or mixer.
- Set the mix slide pot (fader) to the middle position, which represents the original Juno balance.
- Turn the module on by powering up your Eurorack system.
Now, you should be able to hear the chorus effect applied to your audio source. Experiment with different settings and adjustments to explore the various modes and parameters of the Chorus 6 module. For a more detailed control over the chorus effect, you can switch to the manual mode by pressing the MAN button and delve into the different parameters.
Remember, the Chorus 6 offers plenty of sonic possibilities, so don't be afraid to experiment and let your creativity flow. Enjoy exploring the beautiful and immersive Juno-style chorus effect with the SoundForce Chorus 6 module!
Now that we have explored the different modes and parameters of the SoundForce Chorus 6, let's dive into an intermediate-level usage example that demonstrates its versatility and creative potential.
Imagine you have a melodic sequence running through your Eurorack system, and you want to add a touch of lush and spacious chorus to enhance the sound. Start by connecting the mono output of your sound source to the Chorus 6's mono input. Adjust the input level switch to Euro if you're using Eurorack levels.
Next, set the Chorus 6 to the MAN (manual) mode. This will give you full control over every parameter of the chorus effect. Dial in the desired mix between the dry and chorused signal using the mix slide pot or explore dynamic modulation by patching a CV signal into the mix CV input.
To create some beautiful modulation, set the time slide pot to determine the starting delay time. Then adjust the rate slide pot or connect a CV signal to the rate CV input to control the speed of the modulation. Experiment with different LFO waveforms by selecting one from the available options. You can further shape the modulation by selecting a frequency range that suits your musical context.
Now, let's add some depth to the modulation. Use the depth slide pot or connect a CV signal to the depth CV input to control the intensity of the modulation around the starting time. Be cautious not to push the modulation depth too high, as this may introduce noticeable artifacts. Remember, if you're aiming for a subtle and smooth chorus effect, keep the depth moderate. However, if you want to explore edgier and more experimental sounds, increasing the modulation depth can add character and uniqueness to your patches.
Take advantage of the stereo capability of the Chorus 6 by patching a stereo signal into both the left and right inputs. Each input signal will pass through its dedicated BBD delay line, resulting in a rich and immersive stereo chorus effect. If you're working with a mono source, simply connect it to the left input, and the Chorus 6 will route it to the right output for a wider sound.
Don't forget to experiment with the BBD delay time range, pushing it towards its extremes to add interesting artifacts and textures. However, keep in mind that excessive modulation depth may introduce unwanted squeaks and whines, so adjust it according to your desired outcome.
As you explore the SoundForce Chorus 6 and incorporate it into your musical compositions, you will discover endless sonic possibilities. Whether you're aiming for classic Juno-style chorusing or venturing into experimental territories, this module offers an array of creative tools to elevate your sound.
Let's explore an expert-level usage example for the SoundForce Chorus 6 module. In this scenario, we'll dive into creating dynamic stereo movement with high-frequency modulation.
First, we'll set the Chorus 6 to the MAN (Manual) mode. This mode provides control over every parameter and unlocks the full potential of the chorus effect.
To achieve dynamic stereo movement, we'll focus on the LFO wave and range settings. We'll start by selecting a Triangle waveform as our LFO wave, as it provides a smooth modulation shape.
Next, we'll adjust the range parameter to the "S" setting (30Hz to 500Hz). This range allows for faster LFO modulation, creating more pronounced stereo movement. Experimenting with different ranges can yield interesting results, so feel free to explore the "M" or "L" settings as well.
Now, let's tweak the depth slide pot or connect a CV input to modulate the chorus effect's depth. Increasing the depth of modulation will enhance the stereo movement, adding a more pronounced and immersive effect. Remember that increasing the depth significantly can push the BBD delay times to the extremes, introducing unique artifacts and characteristics.
To fine-tune the chorus effect, we can adjust the time slide pot to set the starting delay time. Experiment with different delay times to find the sweet spot that complements your audio source.
For even more advanced sound design possibilities, we can utilize the EXT IN CV input in the Manual mode. By connecting an external CV source, we can further modulate the delay start time or change the LFO wave and range settings dynamically. This opens up a world of creative possibilities to explore.
Lastly, don't forget to experiment with different input levels. Whether you're using Eurorack or Line level signals, the Chorus 6 can handle both. Adjust the small slide switch between the 2 PCBs to switch between Euro and Line levels. Keep in mind that line level inputs will be amplified to the Eurorack level range at the module's output.
By applying these expert-level techniques and exploring the various parameters and modulation options of the SoundForce Chorus 6, you can create stunning and immersive stereo effects that add depth and movement to your Eurorack system.
