Z-LiveRec is an USB multitrack recorder/player for Raspberry PI 4 & Core Class Audio/ALSA Compliant devices and digital mixing consoles like Mackie DL-16S/DL-32S series and Behringer XR18 &X32 series. It handles 2 to 48 channels, 48Khz, 24 bits recordings over USB 2 and store them into a single multitrack wave file.
Based on Peter Dikant’s excellent post work using bash scripts on a Raspberry PI 3 or 4 as a multitrack recorder for Behringer XR18 – The Z-LiveRec is an complete application created especially for Raspberry PI 4 with (or without) a touched based GUI’s and adopted it to include support for mixing consoles like Mackie DL16S/32S and Behringer X18/X32.
The Z-LiveRec app can both record and replay up to 48 channels over USB from/to the Mackie mixer. Just perfect for live recordings, virtual sound checks and multitrack playbacks. It can generate Wav, W64 or CAF audio files which later can the be imported in to DAWs like Logic X, Steinberg Cubase, Reaper and Protools.
The implementation records up to 48 (or even more) channels, 48KHz, 24 bits over USB on a Raspberry PI 4. For a more portable solution, a Raspberry skin/box with a built in 3.5” display can be used. There are complete screen and case/box solutions on the market for the Raspberry 4. Raspberry have 4 USB ports where two of them supports USB 3 compliant devices. These can be used as USB connections to the mixer and also for storing the multichannel wav or caf file to USB 3.1 based memory stick or SSD drives – recommended is SanDisk Ultra Fit 64GB USB 3.1 which offers the right speed for storage without having any dropouts etc. (EXFAT formatted drives are needed for bigger recordings)
