WHY KEYFLOW?
Less setup. More music.
KeyFlow sits right between your musical impulse and the DAW – making the path so short that technology stops feeling like technology.
Theory stays out of the way
Scale Lock and Chord Mode keep you musically free without slowing you down with menus.
One workflow. Every DAW.
KeyFlow sends true MIDI. Your instrument, your sound, and your project stay exactly where they are.
SEE THE FLOW
Press a key. Stay in flow.
KeyFlow keeps scales, chords, and expression under your fingers – so you can follow the idea instead of the interface.

THE KEYFLOW DIFFERENCE
The instrument already in front of you.

FAQ
Questions, answered.
The most common answers before your first chord. XHL Audio Support is here for everything else.
Open supportWhich DAWs are supported?
KeyFlow works with every DAW that accepts MIDI input for instrument tracks – including Logic Pro, Ableton Live, FL Studio, Studio One, Cubase, Nuendo, Pro Tools, REAPER, Bitwig, and GarageBand.
Which operating systems does KeyFlow support?
KeyFlow includes native installers for Apple Silicon Macs running macOS 13 or later and for Windows 11 PCs with x64 or ARM64 processors.
What is Global Play?
Global Play keeps KeyFlow playable while your DAW or another app is in front. You choose your own global hotkey and use it to switch keyboard capture on or off at any time. On macOS, the first activation requires Accessibility permission so KeyFlow can receive those mapped keys in the background.
Does KeyFlow generate sound?
KeyFlow is a MIDI instrument and intentionally generates no sound of its own. It plays the synth, sampler, piano, or any other instrument loaded in your DAW.
Do I need a MIDI keyboard?
No. That is exactly what KeyFlow is built for: your QWERTZ or QWERTY computer keyboard becomes a playable MIDI controller.
Are updates included?
Maintenance and compatibility updates for your version are included. We will communicate major future versions clearly in advance.
How does the license work?
After payment, your personal license key appears immediately on the confirmation page together with the protected download. Keep the key private and store it safely.
Do I need a permanent internet connection?
No. Purchasing and initial license delivery happen online; while producing and playing, KeyFlow runs locally on your computer.
Can I use KeyFlow on multiple computers?
Yes. One license can be activated on up to two computers you personally own or control, across macOS and Windows. The license key is personal and may not be shared with another person.
