This is not emulation, this is the real deal: This new hardware platform gives Engineers and Creatives the products they want, in the format they need: Portable, flexible and seamlessly integrated.


20th September 2023: Karno today introduces SEPIA, a disruptive new entry into the professional audio market. Eagerly anticipated by leading sound engineers and creatives, based on patent pending technology developed exclusively by Karno, SEPIA puts the signal path of today’s finest outboard and effects units into a compact, modular, digitally controllable package optimised for live, theatre and modern studio workflows.

SEPIA is neither an emulation nor a recreation. Palm-sized SEPIA Modules are created by original hardware manufacturers, incorporating core tonal elements of currently available hardware as well as reviving sought-after extinct designs. SEPIA Modules are accommodated in a Host unit, created by Karno, utilising the Mainframe which contains SEPIA’s Universal Elements (UEs). The Mainframe creates a patent-pending bridging signal flow between Modules and Hosts to recreate the full original circuit, giving engineers and creatives convenient access to their favourite hardware brands in a new, smaller form factor.

With a fast-growing library of SEPIA Modules available from launch, SEPIA users will have access to microphone preamps, equalisers, dynamics processors and effects (including classic vacuum tube designs), as well as DSP units. On the Host side, several Host units are in development to suit all workflow requirements, regardless of channel count.


Tackling the issue of bulky physical controls, as well as providing full parameter recall alongside a rich array of workflow focused features, is SEPIA’s control software, powered by the Karno’s newly developed AEQUOREA engine. From launch, Hosts and Modules can be controlled in three main ways: from a computer (Mac/Windows), tablet or phone (iOS/Android), via DAW Plug-In, and by accepting multiple industry standard control protocols including HUI, EUCON and OSC, with more to come. Alongside its control capabilities, the AEQUOREA engine is also capable of rendering brand specific, familiar GUI information seamlessly on all platforms. Deeper integration with selected console manufacturers is in development and will be announced shortly.

With parameter control covered, routing is up next, the traditional kind as well as the previously impossible. SEPIA’s unique routing capabilities will allow users to create studio-quality channel strips, routing from the Analog Input then from Module to Module, providing the ultimate channel strip for some of the world’s biggest artists, as well as create totally new and unheard sonic characteristics by splitting Module circuits at a manufacturer-approved point and routing the audio between these stages. This allows for routing capabilities like leaving a Module after its input stage and weaving into the next Module to catch only its output stage. It’s creative freedom, but in the analog domain.

Whilst feature rich, channel for channel SEPIA offers a far higher channel density at a lower cost than corresponding full-size processors. The user can gain back precious space, while rental companies can strengthen their outboard inventory to cater for large-scale projects. Each Module’s space-saving design is at least 60% smaller than that of the nearest modular option. For rental and production companies this substantially slashes the cost and carbon emissions of freighting gear from venue to venue on large-scale international tours. Additionally, the reduction of components needed for each SEPIA Module lowers material costs to Module manufacturers, whilst their designs benefit from all the platform has to offer including a programmable, Module-adjustable linear power supply and a novel heat dissipation system.

“We have given over 120 engineers a sneak peek throughout the development of SEPIA and have been overwhelmed by the response. We knew it would be popular, but we thought we may have to convince a couple at least, and by developing the platform alongside these users, we know SEPIA delivers. We also have the world’s finest outboard manufacturers eager to bring their SEPIA offering to the market. The opportunity to broaden their audience to finally include live and theatre is just too big to pass up. In all, the SEPIA platform is truly living up to what we imagined it could be and we just cannot wait to watch as it grows above and beyond”. - Adam Pierce, Director.

Module manufacturers will shortly begin to announce their participation in SEPIA and provide launch dates and specifications for their own Module designs. Following large scale testing and evaluation of SEPIA by some of the world’s biggest artists this winter, shipping of initial SEPIA Host units and Modules will start in 2024, with many more Modules rolling out during the year. There is no longer a reason to compromise, SEPIA is coming.

Industry opinions on SEPIA

“Being able to access analog studio preamps and processors on the road - and digitally control them will be massive! The potential for SEPIA to give me access those colors and textures in a way that is tour-able and fits my workflow is enormous.” – Vince Casamatta, FOH Engineer (Maroon 5).

“SEPIA looks to bring a whole new set of possibilities to the world of Theatre Sound. The flexibility and its incredibly small footprint also cannot be overlooked.” - Phil Hurley, Owner (Stage Sound Services).

“I’m super excited about the prospect of integrating even more colour and texture into my workflow with SEPIA’s analog Modules, whilst retaining a digital I/O path and full recall capability” - Paul Gatehouse,
Theatre Sound Designer (Mary Poppins, SIX, Mandela).
