'Sonic X-Voice' - Human Vocal Patch from our Klaus Schulze Tribute video with Sonic XV Eurorack VCF

This Patch of The Week shows how the vocal sound was created that featured in the Klaus Schulze tribute video. It uses the Sonic XV Diode Transistor Ladder Filter for both it's band pass filter, and it's built-in wave folder. Patch sheet at the end of video, plus a download link for a PDF version with notes further down the page.

The Sonic XV is a surprisingly flexible multimode VCF - it can do the kind of aggressive, screaming resonance chaos that you'd expect from some of the famous diode filter-wielding synths of the past, but it's also particularly good at softer, delicate sounds, and having a well-featured wave folder on board gives it a much wider scope for tone-shaping. This, coupled with it's fast response, and simultaneous band pass, 6dB and 24dB low pass outputs, makes it a great choice for fast melodic sequences and percussion sounds. It's character is significantly different than that of the Minimoog-based Transistor Ladder Filter, and compliments it nicely, even if only used for it's wave folder to feed other VCF's.

The AJH SYNTH Eurorack range consists of high-end modules, all hand-made in the UK, most of which are based on classic, vintage designs, authentically recreating the circuitry of much sought-after analogue instruments and technologies of the past, whilst greatly expanding them, and bringing them to modern Eurorack levels of convenience, limitless flexibility, and reliability.
Check out the AJH Synth playlists for module 'User Guides', and 'Patch of The Week' videos, which will be either performances or 'how to' guides, detailing functions/methods, and a range of sounds, some familiar, some less so, containing a patch sheet at the end to show you how to construct it for yourself.

Patch notes:
--------------------
Green dots show approximate pot and switch positions. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions.
DH-ADSR: As we are using the inverted output here, it will constantly be sending a +8V signal to the LIN-CV of the VCO (therefore raising it's frequency/pitch) until it receives a gate signal, at which point it will follow the envelope settings, starting from an output of 0V. This is why the VCO will need re-tuning to match other instruments used, but preferably after you are happy with the amount of envelope to pitch influence you have dialled in.
Dual LFO: The Tap Tempo VC-LFO module could also be used here in the same way, as it also has a built-in VCA (level control).
Sonic XV: Small differences in wave folder settings can make a big difference to the sound, so it'll probably require some fine-tweaking to get the ideal timbre. I have added some resonance in this version, as it can help to simulate the tone of a human voice, but this is of course subjective - all voices are different. Band pass is definitely the best filter type to use, as it can remove both high and low frequencies that would be beyond those produced by a human voice.
Modules used from left to right: DH-ADSR Envelope, Dual LFO + VCA, Vintage Transistor Core VCO, Sonic XV Diode Filter, Contour Generators, Discrete Cascaded VCA.

Such a great sound. Sometimes I hesitate to click on these videos cause I know it'll make me want to buy another module haha

[@AJHSynthOfficial]

Thank you Juan. Yes, I know that problem well ;)

Interesting how the audio level into the filter creates some pleasing timbers. You referred to these timbral changes as wave folding. How can this filter do wave folding just by adjusting the input level. It also very reminiscent of Isao Tomita.

[@AJHSynthOfficial]

Thanks for your comment. It's the wave-folder section producing those sounds, not the filter section. Wave-folding is very dependant on input signal level, so increasing and decreasing the input level causes the variations in timbre that you are hearing.

[@usaroman]

Thanks, I missed the wavefolder feature on the first pass. Ok, now that makes sense. Interesting to have the wavefolder feature in the filter as opposed to a discreet function in an oscillator or something to that effect. I'm an old timer and prefer old school patches. Totally loved the Berlin school demo on the MiniMod Keys. Im saving up, maybe for Christmas. Thanks for the reply and for brings us world class hybrid classic and modern designs.🎉

[@AJHSynthOfficial]

That's great to hear, thank you. The Sonic's wave folder is still a discrete circuit, which means that with the filter wide open and no resonance it can also be used purely as a wave folder, so it's more like 2 modules in 1. Glad you liked the Berlin school demo, the MiniMod Keyz is ideal for this - sonically it's got the Minimoog sound with the flexibility of the huge Moog modulars used by artists in the 70's, but also with modern functionality, interfacing, even an arpeggiator.

Beautiful

Thanks again

Amazing sound recreation. Thanks for the trip to the 70s !

[@AJHSynthOfficial]

You're very welcome, glad you enjoyed the ride.

Great gig in the sky!! I’m giving it all she’s got captain.

Brilliant synthesis!
