Apple held a private demo for professional musicians at the NAMM music show in Anaheim this weekend to show off its new MainStage live performance application. Leading the demo was the legendary composer and musician Herbie Hancock.

MainStage was released as part of Logic Studio last September and gives musicians a new way to have the power of Logic Pro in a live environment. MainStage allows the user to customize the setup of each individual knob and slider so that it can easily be seen while on stage performing.

One feature that Hancock particularly liked was MainStage’s floating split points. This allows you to split the keyboard into zones so you can play multiple instruments across a single controller. The floating points are dynamic, which means you won’t trigger an adjacent sound by mistake.

"I always wished there was something like this to zone my keyboard," said Hancock. "MainStage must have a brain because it figures things out for you."

Hancock was also asked questions from the invited guests about his thoughts on technology in music. As a long time Apple user, Hancock said he was happy with the versatility that technology provided him.

"One of the things that is really great is being able to manipulate sounds and I don’t have to change my instruments to make it happen," Hancock.
