Oh! rhythm patterns

In this new update, the Oh! has gained new locally stored rhythms that can be toggled with the left and right buttons while in Offline mode, below you can find a description and details about each pattern, as well as a waveform to showcase the movement.

Duration: 0.19s

Peak Frequencies: ~91 Hz, ~65 Hz, ~120 Hz

This waveform creates a slow, rolling pulse, similar to the natural waves of arousal building in the body. It feels like a deep, rhythmic pulsation, much like waves washing over the skin or the rhythmic contractions of a slow, teasing touch. The vibration does not remain steady but instead rises and falls in intensity, mimicking the way the body naturally responds to stimulation over time.

Sensation characteristics:

Expected Effects:

The strong amplitude modulation (AM) ensures that the vibration is not monotonous, but rather has a breathing quality, helping to gradually warm up sensitive nerve endings without numbing them. Because the dominant frequency is ~3 Hz, the pulses are slow and intentional, preventing over stimulation while still building anticipation. The presence of 48 Hz and 95 Hz harmonics contributes to a sense of depth and variation in the vibration.

Peak Frequencies: ~91 Hz, ~65 Hz, ~120 Hz

This waveform has a fast, fluttering quality, like the light brush of fingertips over the skin. The higher-frequency components create a ticklish, thrusting sensation that feels airy and electric. With higher frequency content in the FM modulated pulsations, this waveform delivers quick, tremors that activate surface nerve endings without overwhelming deeper receptors.

Sensation characteristics:

Expected Effects:

The dominant frequency of ~91 Hz provides a strong mid-range vibration, giving the sensation of a quick, precise flutter that stays localized to specific areas of the body rather than spreading. The presence of ~65 Hz adds some depth, while 120 Hz keeps the vibration feeling lively and active. This is excellent for heightening awareness and making the body more responsive to deeper, consistent stimulation later on.

Duration: 0.49s

Peak Frequencies: ~68 Hz, ~48 Hz, ~6 Hz

This waveform delivers an asymmetric, warming vibration that gradually builds in intensity, much like the feeling of heat spreading across the skin. The sensation is present but not aggressive, making it ideal for sustained stimulation without numbing the skin. Unlike fast, flickering vibrations, this pattern maintains a sense of grounding and connection to the body, keeping the experience immersive and continuous.

Sensation characteristics:

Expected Effects:

The dominant frequency at 68 Hz provides a solid mid-range vibration, with 48 Hz contributing to a deeper undertone and a 6 Hz amplitude modulation ensures that while the vibration is continuous, it does not feel flat or monotonous—instead, there’s a natural, rolling ebb and flow that keeps the body engaged.

Duration: 1s

Peak Frequencies: ~58 Hz, ~1.00 Hz

This waveform delivers a deep, pulsing rhythm designed to sync with the body’s natural anticipation and arousal. The steady vibration at 58 Hz provides a firm, present sensation, while the 1 Hz ultra-low modulation introduces a slow, rolling build-up—mimicking the natural wave of increasing pleasure. The rhythm is grounding yet enticing, encouraging full-body engagement while heightening sensitivity. Unlike abrupt or high-frequency patterns that can lead to over stimulation, this waveform moves like a slow, rhythmic caress, awakening the body in layers. It feels immersive, with a deliberate ebb and flow that invites relaxation while enhancing arousal.

Sensation characteristics:

Expected Effects:

The 58 Hz vibration stimulates surface-level nerve endings, creating an initial tingling sensitivity, while the 1 Hz modulation adds a slow, rolling undertone—like a deep, rhythmic breath moving through the body. This combination keeps the experience dynamic, ensuring that sensation doesn’t plateau too quickly, but instead lingers, allowing tension to build in waves.

Duration: 0.32s

Peak Frequencies: ~53 Hz, ~6.18 Hz

This waveform has a deep, lope-y and rumbly quality—like slow, rolling waves crashing in the distance. It’s textured but not chaotic, creating a steady pulse that keeps the body engaged without forcing a direction. There’s a subtle percussive rhythm to it, like the faint beat of a drum in the background, enough to keep awareness alive while letting arousal breathe. Unlike sharper, buzzing vibrations that demand attention, this one doesn’t rush or push—instead, it allows for a moment of lingering, suspending the body in deep sensation without numbing it. The rhythm is just unpredictable enough to keep the experience from feeling static, but stable enough to let the body settle into it.

Sensation characteristics:

Expected Effects:

The 53 Hz frequency provides a firm, steady vibration with enough depth to feel enveloping rather than sharp. The percussive nature of the waveform prevents the body from fully adapting, ensuring the sensation stays fresh and present. Instead of pushing toward a peak, it creates a space for desire to linger, allowing arousal to deepen without forcing escalation.

Best Used In:

Duration: 0.12s

Peak Frequencies: ~48 Hz, ~95 Hz, ~120 Hz

This waveform delivers a rapid, percussive tapping effect, layered over a deep, rumbling undercurrent. Instead of a continuous buzz, it has a highly dynamic attack, creating rhythmic pulses that hit with urgency. The sensation is fast, consistent, and insistent, mimicking the body’s natural contractions during climax. The amplitude (AM) and frequency modulation (FM) create a structured rhythm rather than a chaotic burst, maintaining control while still feeling intense and driving. The compressed wave shape ensures each pulse has a sharp onset and a firm body, giving it an almost drumming effect against the skin.

Sensation characteristics:

Expected Effects:

The 48 Hz frequency establishes the core deep, grounding sensation, the lower frequency rumble keeps the body engaged, while the higher frequencies add precision and sharpness. ppBecause of the compression effects, each pulse hits crisply without blurring together, keeping the body on edge. The structured AM/FM modulation prevents overstimulation by introducing micro-pauses, helping sustain sensitivity rather than numbing out. The asymmetric nature of the waveform keeps the user engaged.

Best Used In:

Duration: 0.06s

Peak Frequencies: ~50 Hz, ~65 Hz

Despite its name, this waveform is not well-suited for aftercare. Instead of a gentle, winding-down sensation, it delivers a fast, insistent pulsing effect that feels active and commanding. The 50 Hz carrier frequency forms a strong, structured foundation, while the 2 Hz frequency modulation (FM) creates a rhythmic surging that prevents the body from fully settling. The short 0.06s duration results in rapid cycling, making it feel immediate and unavoidable rather than soothing. A low-pass filter at 65 Hz removes sharp edges, keeping the sensation deep and controlled, but the amplified output ensures each pulse still hits with intensity. The result is a high-energy, modulated vibration that demands attention, making it more fitting for peak stimulation than relaxation.

Sensation characteristics:

Expected Effects:

The 50 Hz carrier frequency delivers a firm, structured vibration that remains present and persistent, while the 2 Hz FM modulation introduces a shifting quality that prevents the sensation from feeling monotonous. This combination creates a sensation that feels both forceful and engaging, avoiding the kind of steady-state hum that can lead to sensory adaptation. The low-pass filter at 65 Hz smooths out high-frequency noise, keeping the vibration deep and resonant rather than buzzy or sharp. Amplification further intensifies the signal, making it feel stronger and more insistent, reinforcing the sense of urgency. This waveform is less about gentle stimulation and more about driving the body toward peak intensity.
