I've given it a seeing to this morning on the way into work - I'm massively impressed with the sound it puts out.
The dual engine really pushes this beyond anything else on the iPad at the moment, its capable of some insane noises.
The onboard fx are actually quite useful - not really a fan of using onboard fx usually, preferring to address this in the mix, the only thing its lacking compared to Nlog is a brutal eq.
So, I almost said it - move over Nlog, I still love you, but there's a new girl in town, and we've exchanged numbers
