In alpha
Control the parts you need
In alpha, adjust vocals, drums, bass, guitars, keys and other stems independently to support the musicians who are actually playing.
Private alpha — tested in a live church environment
Worship playback,
shaped around your team.
DUCO is a desktop multitrack playback app for worship teams. Prepare setlists, customise song arrangements, control individual stems and route audio where your church needs it.
We’re inviting a limited number of churches to help test DUCO across different teams, computers and audio setups.
Windows private alphamacOS planned
The reality of Sunday
Your team changes from week to week.
Your tracks should be able to change with it.
A studio arrangement rarely maps perfectly onto every live team. One week you have a full rhythm section; the next, a keys player and two vocalists.
Worship teams need independent control over stems, click and guide, plus routing that makes sense at the sound desk. When the service begins, playback should keep working without depending on the internet.
Built for the room you’re in
Playback that adapts
when the team changes.
Each part of DUCO is being developed around the practical work of preparing, rehearsing and running a service.
In alpha
Build your own arrangement
Alpha tools let testers reorder, duplicate or remove song sections so playback can follow the version their team intends to lead.
In alpha
Prepare the whole service
Setlist workflows are being tested to keep songs and the information needed for rehearsal and Sunday together.
In alpha
Route every output clearly
DUCO is being designed to send stems, click, guide and other channels to the outputs required by compatible hardware and a sound desk.
In alpha
Keep playing offline
Live playback is designed to run from locally prepared material without depending on a stable internet connection.

Designed around live worship
DUCO is being shaped through real rehearsals, services and feedback from worship and production teams.
How it works
From source audio
to Sunday setlist.
- 01
Prepare the song

- 02
Shape the arrangement
Set levels, define song sections and build the version your team intends to lead.
- 03
Add it to the setlist
Route the outputs, rehearse the transitions and run the service.
Private alpha
Help shape DUCO
in real churches.
DUCO is moving into private alpha testing. We’re looking for a small number of churches willing to test it during rehearsals and, when appropriate, live services.
Alpha software may contain bugs. Early testers should begin in rehearsal and keep a reliable fallback playback method available.
A GOOD FIT FOR
- 01 Worship leaders and musicians
- 02 Playback operators
- 03 Church sound engineers
- 04 Production volunteers
- 05 Teams using an interface or digital desk
- 06 Teams ready to give clear feedback
Straight answers
Questions,
before you join.
DUCO is early. Here’s what that means in practice.
What is DUCO?
DUCO is desktop playback software for worship teams, focused on controllable stems, custom arrangements, service setlists and clear audio routing.
Is DUCO available now?
DUCO is entering private alpha and is not yet generally available. A small number of suitable churches will be invited to test early builds.
Which operating systems are supported?
The likely first testing programme is a Windows private alpha. macOS planned; it is not currently being presented as supported.
Does DUCO work offline?
Live playback is designed to work offline once the required material has been prepared locally. Some import or processing operations may still require other resources.
Can DUCO send stems to separate outputs?
DUCO is designed for multi-channel output through compatible audio hardware. Actual channel counts depend on the computer, operating system, driver, audio interface and selected configuration.
Does DUCO provide the music?
No. DUCO is playback and preparation software. It does not sell, supply or license commercial recordings or song catalogues.
Can I import any song?
You are responsible for ensuring that you have the rights and permissions needed to copy, process, rehearse, perform or otherwise use any audio you import. DUCO does not grant music, recording, publishing or performance rights.
Does stem separation always produce perfect results?
No. Separation quality depends on the source recording, arrangement and processing method. Some songs separate much more cleanly than others.
How much will DUCO cost?
Pricing has not been finalised. Private-alpha testers will be told clearly about any costs before being asked to commit to anything.
Is this intended to replace musicians?
No. DUCO is intended to support the team that is present, fill genuinely missing parts where appropriate and give worship leaders more control over arrangements and playback.
