I'm currently working on sfp 4.0 (I own 2 Pulsar2 cards+SyncPlate)...and everything is fine.

Is there any good reason to upgrade to sfp 4.5? I mean, I'm gonna purchase some Sonic Timeworks (Mastering compressor and others) and Wolf Audio (SpeQtrum and others..) plugins...will I meet problems with the 4.0?

Thanks
