Formatting the MicroSD Card

If the card is already formatted, after being inserted an icon will appear on the home screen of the unit showing the available recording time, and the ‘REC’ button in the top-left of the screen will turn green. If the card is not formatted (or is not formatted using a file system recognised by the RØDECaster Duo), a dialog box will appear asking you to format the card.

Note: Formatting will delete all files on the card. You can also format the card manually by clicking on the card icon on the main screen, and then selecting ‘Erase’.

Formatting the USB Storage Device

If the device is already formatted, after being inserted an icon will appear on the home screen of the unit showing the available recording time. If the device is not formatted (or is not formatted using a file system recognised by the RØDECaster Duo), a dialog will appear asking you to format the device. Formatting will delete all files on the device. You can also format the card manually by clicking on the storage icon on the main screen, and then selecting ‘Erase’.

Starting and Stopping the Recording

To start a recording, press the ‘REC’ button in the top-left of the screen. The ‘REC’ button will turn red, and a timer will indicate how long your elapsed recording time is. To stop recording, press and hold the ‘REC’ button.

Note: The above method is called ‘Press to Pause Recording Mode’, which is activated by default. In this mode, a short press will pause the recording. You can switch to ‘Press to Stop Recording Mode’ by going to settings, then ‘Display’ > ‘REC Button’. In this mode, a short press will stop the recording and a press and hold will pause the recording (see below for more info).

Pausing the Recording

To pause a recording, short press the ‘REC’ button. The button will turn orange, and the recording will pause. To resume the recording, press ‘REC’ again. To stop the recording while in the paused state, press and hold ‘REC’ again. You can also pause the recording by long-pressing the ‘REC’ icon at the top left of the home screen.

Note: The above method is called ‘Press to Pause Recording Mode’, which is activated by default. You can switch to ‘Press to Stop Recording Mode’ by going to settings, then ‘Display’ > ‘REC Button’. In this mode, a short press will stop the recording and a press and hold will pause the recording.

Placing Markers

You can place a marker at any point during recording. These can be used to locate sections of your recording when playing them back or when they are imported into a DAW (note: not all DAWs are able to read marker information in audio files; check the documentation for your DAW for more information). To place a marker, simply tap the recording timer whilst recording.

Activating Multitrack Recording

When recording on the RØDECaster Duo, you can select to record either the full stereo mix or each track individually (plus the full stereo mix). The latter is called multitrack recording and allows you to edit your tracks individually in post-production if needed.

To activate multitrack recording, tap the settings cog then ‘Outputs’ > ‘Multitrack’ (by default, multitrack is set to ‘off’). From this page you can either set it to ‘Pre-fader’ or ‘Post-fader’. Recording pre-fader means that the position of the fader will have no effect on the audio being recorded – i.e. even if the source is faded down, it will still be recorded at unity gain. Post-fader means that the audio will be recorded at the level set by the fader – i.e. if a source is faded right down, nothing will be recorded.

Note: The ‘mix’ output will not be affected by this setting and will always reflect the final mix output, including fader positions.

Bypassing Processing (Multitrack Recording Only)

When recording in multitrack in ‘Pre-Fader’ mode, you can choose to exclude processing from your recordings. This means that the raw audio will be recorded without any of the channel processing applied (i.e., the APHEX processing or effects). The ‘mix’ output will not be affected by this setting and will always reflect the final mix output including all processing.

Listening to your Recordings

You can play back your recordings directly from the RØDECaster Duo. To access your recordings, navigate to Settings > ‘Show’ > ‘Recordings’ icon. A list of your recordings will be displayed. To access a recording, tap on it. To play back your recording, tap on the ‘play’ icon. Note: all other audio functions on the RØDECaster Duo will be muted when the playback screen is open.

Navigating Through a Recording

There are several ways to navigate through the file when playing back audio. You can use the slider at the bottom of the screen, the ‘jump’ icons to move back and forward through the audio in 15 second or 30 second increments, or advance through any markers you may have placed in the recording.

Trimming and Editing a Recording

You can trim the start and end points of a recording as well as adding in a fade in and fade out. To do this, activate edit mode in the playback screen by tapping on the scissor icon. You can now drag the corners of the waveform to trim the audio and create a fade in or fade out. To preview your edit, use the play controls. Press the green tick in the top right corner of the screen to save the edit and exit edit mode.

Selecting the Main USB Device on your Computer

The RØDECaster Duo features three USB audio devices that your computer will recognise. The USB 1 output has two USB devices called ‘RØDECaster Duo Main’ and ‘RØDECaster Duo Chat’. The USB 2 output will be recognised as ‘RØDECaster Duo Secondary’.

We recommend using the ‘RØDECaster Duo Main’ (USB 1) for recording your production, as this is the only device that can be configured as a multitrack device. Make sure you select the ‘RØDECaster Duo Main’ device as your input either in your computer control panel or in the devices section of you recording software or DAW.

Switching Between Stereo and Multitrack Recording Mode

By default, ‘RØDECaster Duo Main’ (USB 1) is configured to output the main stereo mix (all of your audio inputs mixed together). To activate multitrack recording via USB, go to settings then ‘Outputs’ > ‘Multitrack’ > ‘USB’ and deselect ‘Off’.

Note: USB 2 and USB Chat cannot be configured as multitrack outputs.

Pre- or Post-Fader Recording in Multitrack Mode

When recording individual tracks to your DAW (see ‘Multitrack Recording via USB’ above), you can select to record the audio either pre- or post-fader. Recording pre-fader means that the position of the fader will have no effect on the audio being recorded – i.e. even if the source is faded down, it will still be recorded at unity gain. Post-fader means that the audio will be recorded at the level set by the fader – i.e., if a source is faded right down, nothing will be recorded. You can select pre- or post-fader recording by tapping the settings cog then ‘Outputs’ > ‘Multitrack’. The ‘mix’ output will not be affected by this setting and will always reflect the final mix output, including fader positions.

Bypassing Processing

When recording in multitrack, you can choose to exclude processing from your recordings. This means that the raw audio will be recorded without any of the channel processing applied (i.e., the APHEX processing or effects). The ‘mix’ output will not be affected by this setting and will always reflect the final mix output including all processing.

Starting the Recording

In its default configuration, the RØDECaster Duo’s on-screen ‘REC’ button will not start the recording in your DAW or recording software. To start recording, check your track(s) are armed, and that the input is set to ‘RØDECaster Duo Main’. You can then start recording in your DAW.
