Choruses are some of the simplest audio effects to get a rich sound out of a simple oscillator; due to the simplicity of the effect, many power users in this community have made one, and they have different approaches: acheney uses the classic vibrato effect; SawZer’s Hyper Chorus uses delay modules; Trackerbound uses pitch shifter and feedback to duplicate voices.
I also had one stereo chorus too, and it was based on the sound in NanoStudio which the LFO speed in left and right channel were in one to three ratio. (but you have to adjust that ratio manually) I have used that chorus since 2012, and it has even appeared in Mech Haven or some later tracks. Until one day, I was wondering if modulator can build a compact chorus, and obviously it works because modulator in phase mode is basically a pair of delays in separated channels, so we can build a chorus by adding a stereo sine LFO:
The “Get ‘Rich’ Quick Scheme” for Chorus Module, all you needed is a LFO and a Modulator
That is surely a chorus, but the functionality is a bit limited, so I added another modulation stage with different LFO frequencies, doubling the number of voices from the previous stage, and added a feedback stage and an experimental destructor effect (audio signal affects LFO waveform at feedback stage), doubled as an echo and a distortion affects; thus, C->Horus was created.
People would argue: “Isn’t this is the same C->Horus in the SunVox default effect folder?” No, this is the improved version of the original C->Horus with more voices while the feedback should be more stable due to the input voice detector, and the Eq is more useful than before. However, the latest version uses much more CPU then the original C->Horus.
Guides and Tips:
C->Horus II should sounds nice out of the box, so you don’t have to tweak the module before using it. It also includes 12 distinct presets, including a clean init patch, so you may use one of the present for your work. Similar to Accipiter or CaRaCaRa, connect the factory preset to the C->Horus and press any note to pick one of the presets.
If you really want to tweak the chorus from sketch, I would recommend the following way:
Choose the init preset, located at the C note of the factory preset, or simply set the destructor, feedback, modulation intensity and frequency to 0 with reset EQ, with wet signal all the way up.
Try to increase the frequency and intensity of the Tier 1 modulator, you should get some rich phasing effect. Once you have figured out how it works, you may also tweak the second stage, to find the sweet spot for your instrument. Tier 2 is optional because it might cause some cancelling, making the sound a bit duller, despite being richer an lusher. You may also try to change the random seed to reduce the cancelling, flanger like effect.
You may further richen the sound by introducing the feedback, and this feature brings your modulated signal back to the first chorus stage. Don’t worry if you have applied too much feedback because the feedback will be killed slowly if nothing is feed into the module. You can also change the delay time of the feedback stage, doubling it as an echo module.
If you want some distortion effects, you can slide up the destructor effect; this will extract the sub frequency (<50 Hz) from each stage of the chorus, and feeding those signal into the corresponding LFO stages, distorting the clean sine signal to produce some unpredictable distortion effects.
That’s all about it! Enjoy this new chorus!
