UDO Audio’s Super 6: Unlocking LFO 1’s Secret Modulation Arsenal

The UDO Super 6 is introduced as a versatile analog-hybrid polysynth, but this video quickly pivots to a feature that many users may have overlooked: a hidden modulation capability within LFO 1. Hazel, the presenter, sets the stage by emphasizing how this under-the-radar function can bring an extra layer of character and unpredictability to your patches—something that goes beyond the expected palette of standard LFO shapes.

This hidden gem isn’t just a minor tweak; it’s positioned as a workflow enhancer for those who want to push the Super 6’s modulation architecture further. By accessing alternative waveforms not shown on the main selector, users can unlock new sonic territory, giving their patches a unique, evolving quality that stands out in both studio and live contexts.

Diving into the architecture, Hazel explains that LFO 1 on the Super 6 isn’t limited to the visible waveforms on its selector. Instead, there’s an entire bank of alternative, irregular waveforms—each with its own unpredictable cycle and harmonic richness. These shapes aren’t just for show; they’re designed to inject complexity and surprise into your modulation paths.

The process for accessing these waveforms is straightforward: hold shift and nudge the LFO 1 waveform selector left or right to assign an alternative shape. This opens up a world of modulation possibilities, as these waveforms can impart overtones and rhythmic quirks that standard LFOs simply can’t achieve.

The video doesn’t just talk theory—it delivers hands-on demonstrations. Hazel starts by routing these alternative LFO 1 waveforms to modulate the filter cutoff, showcasing how the irregularity adds nuance and evolving detail, especially at slower rates. When the speed is increased, the modulation takes on a rhythmic, almost sequencer-like quality, highlighting the versatility of these waveforms.

Beyond the filter, Hazel explores modulating pitch, VCA, and even pulse width on oscillator 2 (DDS 2). Each destination responds differently to the alternative waveforms, producing everything from tape-like warble to stepped, wasp-like effects. Cycling through various shapes and speeds, the Super 6 reveals a broad spectrum of modulation-driven sound design, all accessible from this hidden LFO bank.

UDO’s modulation system doesn’t stop at waveforms. Hazel highlights additional features within LFO 1 that further expand creative potential. By toggling between reset and free modes, users can decide whether the LFO retriggers with each note or runs continuously, dramatically affecting the movement and cohesion of modulation across voices.

Stereo depth is introduced via phase shifting, allowing the left and right channels to move out of sync for a wider, more immersive sound—especially noticeable on headphones. Modulation delay and one-shot (once) modes add even more architectural flexibility, enabling timed entrances and single-cycle modulations that interact with envelopes for intricate, layered effects.
