Apparently on the new StudioLive 3 mixers, the only Capture sessions you can play using the Sound Check feature on the mixer are ones recorded on the mixer. When you first get the mixer out of the box, it would be great in you could play a prerecorded session using the onboard Sound Check feature to try things out and get some experience with the mixer. Can PreSonus provide some demo sessions, either downloadable or included on an SD card, for this purpose?
NOTE: I'm aware that you can load up prerecorded material to Capture on a PC/Mac and play that through to the SL3, but I'm talking about doing it directly from an SD card inserted into the mixer using Sound Check
