• Your phone and the computer running auxCord have to be on the same Wi-Fi network. On a separate guest network, auxCord will not show up.
• Phone on the wrong network? On a Mac, Studio Connect in auxCord shows a QR code that puts guests on the network the studio Mac shares.
• Make sure auxCord is loaded on a track; it only appears while the plugin is open in your DAW.
• Still not there? Restart the phone, then try again.
• On Windows, the firewall can block the connection: see Windows firewall.

• The device is waiting to be allowed. New devices ask first: click Allow (or Always allow) in auxCord’s request strip.
• auxCord isn’t activated, or the trial has ended. Devices still connect and their meters move, but the audio stays silent until auxCord is activated. Click Activate in auxCord’s header.
• The device is muted, or another one is soloed. Check the S and M buttons on its row.
• In Logic Pro, see Logic Pro.

AirPlay buffers about 2 seconds of audio, so what you hear lags the phone by about 2 seconds. That’s AirPlay itself, not auxCord, and it doesn’t matter for references, voice memos or a client’s playlist. When auxCord sends your mix to Bluetooth headphones, Bluetooth adds a few hundred milliseconds.

Android has no AirPlay built in, so you need an AirPlay app. Users have had good results with AirMusic. Once it is installed, make sure you have given the app root access to your phone; otherwise AirMusic will not be able to stream audio to auxCord.

Sometimes Windows Defender blocks the connections auxCord needs on the local network. To let your DAW through the firewall (Windows 11):

1. Open Windows Security from the Start menu, or search for “Windows Security”.
2. Click Firewall & network protection.
3. Click Allow an app through firewall.
4. Click Change settings (if shown).
5. Select your DAW. Not in the list? Click Allow another app…, find and select your DAW, then click Add.
6. Tick Private and Public.
7. Click OK to confirm.

• Fully quit your DAW, then install auxCord. Some DAWs only rescan plugins when they start.
• Rescan plugins in your DAW’s plugin manager if it has one.
• Pick the format your DAW uses: AAX for Pro Tools, AU for Logic Pro and GarageBand, VST3 for most others.
• Still missing? Download the installer again from Downloads; a broken download is rare but happens.

Try setting up your session like this:

1. Create a stereo audio track and open auxCord on it. Set the input to Bus 1 and the output to Bus 2.
2. Create a second audio track, set its input to Bus 2 and its output to Stereo Out.
3. Set the second track to input monitoring or record, and start streaming audio on your device.
4. Now you can record on the second track.

Click Activate in auxCord. Your browser opens; sign in to your account and choose your licence, or start the 14-day trial. The free trial page walks you through it.

A licence runs on 2 computers at once. To move it:

2. On the new computer, click Activate in auxCord and use your licence.

1. In auxCord, click Activate, then Offline…, and save the device file.
2. On a computer that is online, go to mountainroaddsp.com/activate/offline, sign in, upload the device file and download the licence file.
3. Bring the licence file back to the studio computer and load it in the same Offline window.

Your licence is always in your account, under the email you bought with. If the email didn’t arrive:

• Did the payment actually go through?

If you were charged but can’t find the email or the licence, write to support@mountainroaddsp.com.
