The Grid PBF4 from Intech Studio is a versatile hybrid control module designed to bridge the gap between subtle adjustments and expressive performance. This comprehensive interface combines three essential control types into one robust unit: audio-grade 30mm linear faders with medium resistance, smooth-turning metal shaft potentiometers, and Gateron Hall effect key switches. Ideally suited as a highly portable mixer surface, the PBF4 allows producers to command critical parameters like volume, expression, and modulation with precision. Each control element is backed by a fully customizable RGB LED, enabling users to color-code their layout, adjust brightness, or create pulsing animations for clear visual feedback in dark studio or stage environments. As a member of the Grid Modular Controller family, the PBF4 features an innovative magnetic interface that snaps securely to other Grid modules in any configuration. The device is powered via a high-speed USB-C connection and is class-compliant across Mac OS, Windows, Linux, and mobile platforms. Through the free Grid Editor, users can dive deep into customization—configuring 14-bit high-resolution MIDI, assigning specific MIDI channels, or programming complex behaviors using LUA scripting. With support for SysEx, NRPN, and HID protocols (keyboard/mouse emulation), the PBF4 transforms from a DAW mixer into a powerful creative tool for any audio or visual workflow.
