The teenage engineering EP-133 K.O. II is a compact sampler, sequencer, and composition workstation designed for fast, hands-on beatmaking and portable music creation. Built around immediate workflow and tactile control, it lets you sample sounds, sequence patterns, manipulate loops, and build full tracks without getting buried in menus or complex setup. With a built-in microphone and speaker, the EP-133 is ready for spontaneous recording anywhere, whether you're capturing found sounds, chopping samples, sketching ideas, or building full arrangements on the move. Expanded memory now provides 128MB of storage with up to 999 sample slots, alongside support for 12 stereo voices or 16 mono voices. Sampling, sequencing, and performance controls are centred around pressure-sensitive keys and a multifunctional fader that can automate and manipulate multiple parameters in real time. Filter, pitch, effects, punch-in performance processing, and sequencing controls are all designed for immediate interaction and rapid experimentation. The EP-133 supports up to 9 projects, each containing: - 80,000 notes - 4 groups - 99 patterns per group Each project includes: - 12 sample and MIDI tracks - Variable pattern lengths from 1 to 99 bars - Free or quantised sequencing - Swing control - Real-time parameter automation Stereo effects processing and onboard compression help shape complete tracks directly within the unit, while the punch-in effects system encourages live manipulation and performance-oriented workflow. Despite its compact footprint, the EP-133 offers comprehensive connectivity including: - Stereo input - Stereo output - MIDI in/out - Sync in/out - USB-C Power is provided via either: - 4 × AAA batteries - USB-C making it equally suited to portable production, desktop setups, travel, live performance, and quick idea capture.
