won't be buying anymore of there stuff, there support sucks! big time. mac updates for z3ta 2 are slow. 2 support requests about z3ta 2 crashing anything and everything in logic on mavericks and buggy as Fook!, no reply in 5 weeks.
save your money on z3ta 2, its a good synth but not well supported. get massive or zebra instead.
I need to change how my home studio is setup. I have purchased far too many iPad synths to not be integrating them into my songwriting and recording workflow. In fact, I'm seriously considering selling off my Roland V-Station in order to make space for my iPad atop two of my other synths: Yamaha MOX6 and Roland Fantom X8. Both have a huge variety of sounds, but I'm using more and more plugins in the box (just upgraded to Native Instruments Komplete Ultimate 9) so I rarely use the other synths for sounds.
Their support is about par with many companies. Not as timely as I would like, but mostly they do answer, even if their answer doesn't fully resolve the issue. The Cakewalk forum (including those members that work for them, have been where the real answers happen.
As far as the VSTs mentioned by others, Z3ta+2 works great on my PC, although the supplied sounds for it are mostly attrocious. DimensionPro, I take issue with because the samples in it are boring and the ones you can buy from DSF/Anderton are very lacking. I'm sure it could be a good machine if it had better choices in samples. But right now, I consider it abandonware. Only Rapture and Z3ta+2 are surving for now (but again, the Z3ta sets are being stripped and tweaked to a much smaller set).
SynthMaster and all of the Korg Legacy Collection have been and are great. Perhaps the their problems come more from running on a Mac?
Kind of sad that Apple has effectively stopped listening to their musician base in favor of catering to the 'en masse dj producer' market.
But since Z3ta+ is out there for free as though it were a separate product, and has a different interface, it seems odd for them to treat Z3ta+2 as a merely an upgrade rather than a new (sequel) product. Oh well.
