Feel the pulse of your music through your fingertips with Rumble, the innovative second hardware expansion module designed specifically for the OP-Z. This built-in haptic sub-woofer brings a revolutionary dimension to music creation by combining high-definition vibro-tactile feedback with advanced psycho-acoustic technology.
The sensation is remarkably similar to holding and listening to a powerful sub-woofer, with the frequency response carefully tuned between 10–150Hz to maximise sonic impact whilst keeping energy consumption to a minimum. This thoughtful engineering ensures you get maximum tactile feedback without draining your device’s battery life.
Beyond the immersive music creation capabilities, Rumble includes a silent metronome mode that proves invaluable during live performances. This feature allows performers to maintain perfect timing by feeling the beat through haptic feedback, ensuring you stay locked to the rhythm even in challenging acoustic environments where traditional click tracks might be difficult to hear.
