Rumble is the second hardware expansion module for the OP-Z. It’s a built-in haptic subwoofer, using high-definition vibrotactile feedback and psychoacoustic technology, allowing you to feel your music.
When using rumble you will feel like you’re holding and listening to a deep sounding subwoofer. the frequency response 10 – 150 hz is designed to maximize impact while minimizing additional energy consumption. It also features a silent metronome mode, great when performing live to always know exactly where the beat is.
So-called haptic technology has become a buzzword in music tech – and broader tech in recent years. Products such as the Subpbac, Basslet, and of course Native Instruments Kontrol S4 give you the sensation of ‘hearing’ low frequencies as they’re translated into vibrations. In a similar vein, the rumble’s subwoofer makes use of high-def “vibrotactile feedback and psychoacoustic technology” to make it seem as though you’re actually listening to a subwoofer.
Rumble retails at $89. More information can be found here.
