Recording
TouchMix makes it easier than ever to capture a live performance in a stereo or a multi-track recording. All you need is a USB hard-drive.
NOTE: Hard-drive requirements – A list of hard-drives that QSC has qualifi ed may be found at qsc.com. There are far too many
hard-drives available for us to test them all so there are certainly many unlisted drives that will work well with TouchMix. Higher speed
drives (>7200 RPM) tend to work best. Some higher speed drives don’t do their best when powered from the USB port but will work
when used with an external power supply. We have also had very good luck with solid state drives. The drive must be formatted as FAT
32 and de-fragmentation improves seek time.
Be sure that there is suffi cient space on the drive for your recording. To calculate the space required for your recording…
• For 48 kHz – Space required (in MB) = 8.64 x minutes x tracks
• For 44.1 kHz – Space required (in MB) = 7.94 x minutes x tracks
It is good practice to have more disk space available than you need. If the drive is nearly full, TouchMix has to look for nooks and crannies of
available space. This will result in fragmented wave fi les and potential loss of audio data and synchronization across tracks. At approximately 3
hours of non-stop recording, the maximum fi le size supported by FAT32 is exceeded. To avoid problems, stop and then resume recording. It is not
necessary to create a new session. TouchMix displays a pop-up that warns you when this limit is approaching. If you do exceed the FAT32 limit, track
synchronization may be lost.
NOTE: Depending on the number of tracks recorded and the performance of the hard drive, multi-track playback may slow down the
rendering of objects on the TouchMix screen resulting in lagging movement of controls.
In general, use 44.1 kHz for CD projects, and 48 kHz for video projects. Do not change sample rate while recording.
