Multitimbrality Comes to Supercritical Synthesizers Redshift 6

Redshift 6 - Multitimbral Techno Tweak video upload by Supercritical Synthesizers

"We are super excited to introduce multitimbrality — it makes the Redshift 6 more than six times more powerful than it already is.

On this demo, we put the Redshift 6’s new multitimbrality feature to the test.

The multitimbrality is currently in beta testing, and this demo uses the beta firmware. The firmware is available on our Discord server. You can join our Discord to access beta versions of the firmware, discuss technical details and development of the Redshift 6, and share demos.

The Redshift 6 is six-part multitimbral, and the new multitimbrality feature makes it possible to assign its six voices in various ways.

The voices can be split into traditional polyphonic keyboard zones, layered across multiple parts to play simultaneously, or, for example, used as six monophonic parts. Thanks to the Redshift 6’s paraphony, these monophonic parts can also be used to play chords.

This demo was recorded live using the Redshift 6’s main and auxiliary outputs. The Dub Chords and Reso Chords were recorded in stereo from the main output and AUX 1. The bass line and noise were recorded in mono from AUX 2.

When the parts are panned left and right, the Redshift 6’s three outputs provide six mono outputs, allowing each of the six parts to have its own dedicated output.

All the synth sounds in this demo were recorded live from the Redshift 6. The drum and FX sounds are samples, created using only the Redshift 6. These samples were sequenced in a DAW after the live tweaking.

We are attending Superbooth 2025 in Berlin. If you're coming to the event, stop by and test the Redshift 6. You can find us at Bungalow B020 in the Bungalowdorf."

Redshift 6 - Arp Line Tweak

video upload by Supercritical Synthesizers

"Redshift 6’s Demon Core Oscillator can create up to 16 analogue oscillators per voice with analogue waveforms.

However, in this synth tweak, we use mostly just two oscillators to create sounds that are inspired by the legendary dual VCO synthesizers.

The MIDI notes are sent from DAW to Redshift, and the delay is DAW’s native delay."

Redshift 6 - Bassline Tweak

video upload by Supercritical Synthesizers

"Redshift 6 is a Variable Character Synthesizer with 5 different characters: Liquid, Crisp, Fat, Mean and Sour.

These characters affect how the filter sounds, and using the different characters, the Redshift 6’s filter can act like almost any classic vintage synthesizer filter and beyond. Besides the filter, these characters also affect the various parameters, from envelope shapes to slop between oscillators.

In this demo, you can hear the different characters with various filter cutoff and resonance settings.

0:00 FAT UNISON BASS
0:44 SQR HOUSE BASS
1:25 SQR SUB OSC BASS
2:05 REESE BASS
2:55 DRIVE UNISON BASS
3:39 ACID SQUARE BASS
4:36 FUNKY UNISON BASS
5:09 LFO SQUARE BASS

The audio is a dry signal from the Redshift 6 without any external effects."

BAF 2025: Supercritical Redshift 6

video upload by sonicstate

"At the Buchla and Friends booth, we caught up with Jussi at Supercritical who demonstrated the *Redshift 6*. This synthesizer, recently made available for purchase, had already been shipping since December. As Jussi explained to us, the Redshift 6 is a six-voice polyphonic synthesizer, each voice featuring a digitally controlled DCO oscillator and a custom-designed filter. The instrument is largely analog, with the exception of its digital effects, allowing for some intriguing sound possibilities.

A standout feature of the Redshift 6 is its extensive modulation capabilities and the ability to generate up to 16 oscillators per voice, resulting in a total of 96 oscillators. The device's filter topology can mimic various classic styles, such as ladder, Roland, and 303 filters, with the potential to introduce new characters over time.

Jussi also shared that the Redshift 6 retails for $1,349."

Redshift 6 - Supersaw Tweak

video upload by Supercritical Synthesizers

"Redshift 6’s Demon Core Oscillator can create up to 16 analogue oscillators per voice. In this synth tweak we use the Demon Core Oscillators Stack feature to create a dense oscillator stack for a supersaw trance sound.

The stereo effect is created by modulating amplifiers panning with voice, so that each new note gets played on the opposite side of the stereo field. The filter cutoff is modulated with slow LFO to create movement to the arpeggiator lines.

Effects in this demo are external effects. All variations from the theme start dry, and the amount of effect is shown in the video."

Redshift 6 - DCO Dreams

"For this retro wave inspired track, we set up three Redshift 6’s that each play their own part.

Bass: LFOMOD BASS - Character: Fat.
Chords: REZSWEEP POLY - Character: Crisp.
Lead: UNISUPERSAW LEAD - Character: Liquid.

Effects in this demo are external effects. Delay: Meris Polymoon, Reverbs: Meris Mercury 7 and Eventide H9"

Redshift 6 - Acid Tweak

video upload by Supercritical Synthesizers

"This demo tweak uses Redshift’s Sour character for its acid sounds.

All the patches in this demo song are made using one oscillator that is fed to the Sour characters 18 dB/Oct filter.

Pitch slides are programmed to the midi notes as pitch bend midi cc messages, and the note velocity modulates the filter cutoff through the filter envelope modulation.

Effects in this demo are all external effects."

Redshift 6 // All Factory Presets // Sounds Only

"Running through all of the Factory Presets in the Supercritical Redshift 6 synth. This is a no talking demo, I've a full breakdown of the concept here: • Supercritical RedShift 6 // Analog We... [posted here]

I've added reverb to the more reverb friendly tones in the first half. I think this gives a better understanding of how the sounds would fit in a mix. If you prefer them in the raw I still got you covered. Jump to the second half. It's the same recordings, same sounds etc, naked."

In this patch we create movement from two cascading LFOs that modulate osc2's pitch and amplitude."

Supercritical RedShift 6 // Analog Weight with Multiple Personalities

video upload by Starsky Carr

"The Redshift 6 is based on the Supercritical Demon Core Oscillator and Neutron Flux Filter eurorack modules.. both of which offer a huge amount of flexibility for analog oscillators and filters. Supercritical have been able to do this through designing a system where they can control the character of the filters and oscillators under digital control.

Which is why this is called a variable character synthesizer. It has 5 distinct characters, from smooth and gooey to nasty and dirty howling resonance.

Although the final firmware has not yet been 100% implemented - I thought it would be interesting to demo the overall principles and how it all works."
