The SEPIA Platform

Explore what makes SEPIA revolutionary

The Platform

Hosts and Innovation

SEPIA is a platform built up of Modules and Hosts. Modules are brought to you by all your favourite manufacturers, while Hosts house them for all scenarios. Karno’s patent-pending Bridging Signal Flow between Module and Host creates a completely analog signal path, exploiting digitally controlled analog infrastructure, to provide a fully featured platform for the modern user.


Original designs from your favourite brands

A SEPIA Module could be anything: from microphone preamps, equalisers, dynamics processors, effects, vacuum tube designs, DSP and more. Brought to you by your favourite brands, SEPIA modules house original components and designs, giving you authentic sound in a modular, compact and durable form factor.


Completing the circuit

To house SEPIA Modules are Hosts. Manufactured by Karno, SEPIA Hosts span the audio industry with forms optimised for all scenarios, from the desktop of a home studio to the stagebox of an arena concert. Regardless of form, SEPIA hosts contain the Mainframe, the heart of the SEPIA platforms technology.


The foundation of the SEPIA technology

Hosts contain the Mainframe comprising of Universal Elements (UEs) and a state-of-the-art routing matrix. UEs are made up of atonal stages redesigned to be as compact and efficient as possible, paired with Karno’s patent-pending Bridging Signal Flow between Host and Module, a complete circuit is achieved. With more packed in, a novel thermal system has been implemented to keep Modules cool, no matter the drive. Hosts also provide the exact power required for each Module’s design, something never before seen in a modular format.


Limitless creativity whatever the workflow

With no physical controls the SEPIA platform utilises all that digital control has to offer with a desktop, tablet, phone and plugin application as well as seamless integration with consoles and controllers powered by the AEQUOREA engine. Build infinite routing and parameter configurations, save them, recall them, control them live. With features built in to cater all workflows the SEPIA control software brings authentic analog hardware into the modern workflow.

Uncompromised Sound

Zero Emulation, Truly Analog

When we say this is the real deal, we truly mean it. Combining original, authentic, Core Tonal Stages within Modules and the atonal Mainframe within Hosts, SEPIA gives you true sound, delivered with zero compromise.


Palm-sized Powerhouses

60% smaller than the nearest modular format and built to withstand the toughest environments, SEPIA Modules are built to travel, cutting freight costs and carbon emissions. The SEPIA platform has a higher channel density than anything ever seen before in analog hardware.

Control From Any Device

Computer, DAW, Console. Your choice

Supporting all major control protocols, SEPIA is controllable by Consoles and a wide range of Control Surfaces. Utilising the ground-breaking AEQUOREA engine, SEPIA’s smart GUI transfer ensures Modules are accurately represented regardless of the display, bringing control into your hands no matter the workflow.

Unlimited Possibilities

Endless Routing Potential

Harness creative freedom never seen before in authentic hardware. SEPIA’s powerful Mainframe (within SEPIA hosts) allows you to sculpt any sound you want. Route from Module to Module, assembling the ultimate channel strip, or even split Modules in half, routing audio between desirable stages, creating brand new sonic possibilities.

Show Critical Features

The show will go on

SEPIA has been designed with the rigours of touring in mind. With a unique, two-point latching system and a strong, aluminium housing, SEPIA Modules are built to last. With redundant power connections and a failsafe audio bypass, SEPIA’s professional Hosts can be trusted to deliver in all situations, regardless how critical.

SEPIA is not emulation.
This is the real deal.

Modules, brought to you by your favourite brands, hold genuine manufacture components streamlined down to their core tonal element.
