SX 2.2 was great until I had an XP issue - I lost my original serial number (fell off the chassis and Digital Village do not keep a record, so no joy there) so had to purchase and install SP2 - forget it - before SP2 it NEVER crashed, since SP2, cannot use MOTU 2408 Mk2 PCI interface as it refuses to record SPDIF without sweeping, frequently hangs and crashes with 828 Mk2, unreliable Halion operation.
The program itself is fantastic (I've been a Steinberg fan since Pro16!) so I would heartily recommend it, and if you have a reliable audio interface it will be fantastic, just try and steer clear of MOTU stuff in conjunction with SP2 until they find a way of fixing it. . . . . (How long has SP2 been out??) Maybe an SX3 upgrade will help in resolving these issues, but somehow I doubt it - such a shame as with SP1 by comparison was absolutely perfect - anyone know where I can buy a legit SP1????
