Although Soundcraft make some of the best small to medium frame hardware mixers on the planet... Their software development team seems to consist of an infinite number of monkeys who may, or may not, accidentally stumble across some code that works. Users of their digital desk routinely keep a couple of revision backups on a smart key just in case something goes horribly wrong during sound-check.
This v2 of their ipad gizmo may represent a major improvement IF and ONLY IF it sends the channel name to the virtual mixing desk.
The last version didn't and this meant that the front of house engineer, mixing from the porcelain throne, had no idea whether he was riding the vocals or turning up the saxophone.
Don't let this put you off Soundcraft digital desks tho. They are the badger's bollocks. When the software works properly.
