Moog may be known for its analog synthesizers, but the company has also crammed those sounds inside iOS apps for making noise on the go. With its latest app for the iPhone and iPad, the company created a digital version of its iconic Model 15 instrument. In fact, Moog says the new app is the first modular synth and learning tool created for Apple's mobile devices. Thanks to Apple's Metal technology, you can pan and zoom around the app to situate those patch cables and tweak nobs in a way that feels natural. Without Metal, the company says this level of detail and smooth movement wouldn't have been possible.
