Hello, and welcome to the Soundcraft Video Manual Series. Today, we’ll continue to expand on some DAW concepts for using with the Ui24R. Now that we’re more familiar with patching audio back into the mixer, let’s try to do it in a multitracking session. With mulitrack playback, you can take audio recorded from the Ui24, and send it back to the same channels on the mixer so that you can practice mixing without your band present. I’ll be using Ableton today, but these concepts will translate to most DAWs available on the market. Let’s get started.
 Ui Patching
. In this example, I’ve recorded a drummer with multiple microphones. Now I want to bring each of these recorded channels back into the mixer on their respective channels so that I can practice mixing with the Ui24. First, we need to head to the Ui24’s settings and select the patching tab. I’m going to be using the Soundcheck feature to easily toggle between the sends coming from my DAW and the mixer’s physical inputs with a single button. On the left side of the patching grid, select the Soundcheck button. This should automatically select the USB-A on the top side of the grid, showing us the default Soundcheck patching of the USB stick channels. Select the USB DAW 1-16 on the top of the grid. I only need 6 channels for this example, but let’s set it up like I want to utilize all of the mixers channels. Simply select the Patch 1 to 1 button in the bottom left side of the patching grid. This will automatically patch our USB DAW channels into every available mixer channel up to the line inputs.  Go ahead and activate Soundcheck by pressing the Activate Soundcheck button in the top right corner of the patching grid. A green “SC” will also show in the snapshot name window to indicate that Soundcheck is ON. 
DAW Setup
. Now let’s go back to our DAW. In the DAW we will again be selecting output channels, but this time for the individual channels instead of our main output. 
In Ableton, you can do this from the arrangement or session view. On the channel, under the Audio To section, change the first drop down selection from Main to External Out. Next, select the output channel for the channel. I’m going to do these 1 to 1 for the 6 channels I need, just like the mixer, but remember that the numbers we select here are equivalent to the blue USB-DAW numbers in the mixer’s interface. Also remember that if you don’t see a particular input or output, make sure that your channels are enabled under the input or output config section of Ableton’s settings. 
Now, press play and you will see all of our audio tracks returning back into individual channels on the mixer. From here I can start to add DSP like EQ and compression and practice my mix without all the pre-gig stress. Don’t forget that to get our mixer’s physical mic/line inputs back into our main mix, we need to disable Soundcheck. You can do this from the patching section again, or from the multitrack tab of the player section. That’s all for multritrack playback, thanks for watching.
