About this app
Together with the URX22C, URX44C, UR22C, UR24C, UR44C, and UR816C audio interfaces, the dspMixFx UR-C app allows you to utilize the benefits of Yamaha’s custom-designed SSP3 DSP chip directly on your iPad and iPhone. The app enables control of all DSP features—including the DSP mixer and built-in DSP effects—on compatible URX-C and UR-C series interfaces. You can create latency-free monitor mixes and streaming mixes for a wide variety of iOS / iPadOS music applications, using acclaimed DSP effects such as REV-X reverb, Sweet Spot Morphing Channel Strip, and Guitar Amp Classics. Please note that this app is only a control application for USB audio interfaces URX22C, URX44C, UR22C, UR24C, UR44C, and UR816C. Without a UR interface it can be used in demo mode only.
