The EP-136 K.O. SIDEKICK is a compact performance mixer, USB audio interface, and effects processor designed as a creative companion for the EP-series ecosystem and portable electronic music setups.

Built around a fast, hands-on workflow, SIDEKICK combines two stereo channel strips, a dedicated stereo aux input, performance effects, and multichannel USB audio into a compact portable format suited to studio production, desktop setups, live performance, and mobile beatmaking.

Designed to pair particularly well with the EP-133 K.O. II and other compact hardware instruments, SIDEKICK offers immediate tactile control over gain, EQ, compression, cueing, effects, and recording without relying on menu-heavy workflows.

Compact Performance Mixer

SIDEKICK provides: - 2 stereo channel strips - 1 stereo aux input - Main and cue outputs - Headphone monitoring - External FX loop capability

Each stereo channel includes: - Dedicated gain control - Configurable EQ - Compressor control

EQ modes include: - DJ - Studio - Parametric

The layout is designed for quick performance adjustments, live transitions, portable jam sessions, and hybrid hardware/software workflows.

Creative Performance FX

A dual FX block provides a range of performance-oriented effects and manipulation tools.

Effects include: - Tap delay - Tape effects - Looping - Tremolo - Filters - Sirens

Performance controls include: - Pressure-sensitive FX pads - High-resolution FX bender - Dual-channel beat matching - Tap-FX Sequencer™

The emphasis is on immediate tactile interaction rather than deep menu navigation, making SIDEKICK particularly effective for live improvisation and portable performance setups.

Features include: - 48kHz / 24-bit AD/DA conversion - 2-channel USB input - 8-channel USB output - Stereo USB playback - Four stereo recording busses: - Channel 1 - Channel 2 - AUX - Main mix
