Apple needs to allow the ability to route audio on the iPad like you can on the Mac. Your point is spot on why that is a limitation on iOS. It can be done but it requires a workaround or external gear. That is not a good experience when there are better experiences, either in the box or things like the MPC. This is not a knock at Koala as we know it's powerful. But it's hamstrung because of Apple.
@@thebl8nlyblatantnetwork stems is that good anyway. It’s so rare to find a stem option that is good on any of these devices or plugins. Honestly I use Serato Sampler for that though. Then record right into Koala or Ableton.
