Routing FL Studio’s Audio to SYQEL

On SYQEL Desktop, pick App Audio: FL Studio in the audio source list. No virtual cable is needed. In the web app, or on a system too old for App Audio, send FL Studio’s output through a virtual audio device instead.

SYQEL Desktop: pick FL Studio directly

1. Play something in FL Studio.
2. In SYQEL, open the audio source list at the left of the top bar. If FL Studio isn’t listed, click the refresh button (↻) next to it.
3. Pick App Audio: FL Studio. The entry uses the name your system gives the app, so it may include a version or edition.
4. On a Mac, the first time you pick an App Audio source, macOS asks for permission. Allow it.

You keep hearing FL Studio as usual. App Audio needs macOS 14.4 or later, or Windows 10 build 19041 or later. On an older Windows build, pick your speakers or headphones instead to capture everything the computer plays.

On Windows the entry may show FL Studio’s program name. SYQEL hears FL Studio only if it plays through Windows audio: if nothing comes through, open Options › Audio settings and set Device to Primary Sound Driver instead of an ASIO driver.

The web app, or an older system: use a virtual audio device

The web app can only hear a microphone or an audio input, not other apps. Send FL Studio’s sound into a virtual audio device, then pick that device in SYQEL.

1. Set up a virtual audio device: BlackHole or Loopback on a Mac, or VB-Cable on Windows. Those guides also show how to keep hearing the music.
2. In FL Studio, open Options › Audio settings and set Device to the virtual device (on Windows, CABLE Input (VB-Audio Virtual Cable); not an ASIO driver).
3. In SYQEL, pick the virtual device in the audio source list, for example BlackHole 2ch, Loopback Audio or CABLE Output (VB-Audio Virtual Cable). The web app adds ”— system audio” to the name.

On a Mac, with Loopback you can instead add FL Studio as a source in your Loopback device and leave FL Studio’s settings alone.

If the Input meter at the right of the stage doesn’t move, see Troubleshooting audio detection.
