Modbap Modular Trinity
Three-channel digital drum synth array for beatmakers
24 HP Eurorack module
Trinity is a 3-channel digital drum synth array in a single 20HP Eurorack module, offering six drum synthesis algorithms (Block, Heap, Neon, Arcade, Clang, Orb) per channel for highly versatile percussive sound design. Each channel features independent pitch, sweep, decay, character, shape, and grit controls, with CV inputs, USB MIDI, stackable voices, and a summed mix output — built from the beatmaker's perspective for hip-hop and beat-driven modular music.
