I am 50/50 on whether or not to purchase a Maschine Studio during this sale period. If NI had included a built-in soundcard, I would have already made the purchase.
With that said, I already own an Elektron Rytm, Akai MPC Renaissance and Arturia Spark. A Maschine Studio is not going to bring me a lot of value in return. However, the gear-head that I am would like to own one, but might wait and verify if the next version includes a sound card, which I find very beneficial when using the Akai MPC Renaissance with a laptop outside of my studio room setup.
