Sync³ Remote, formerly Synclavier® Touch, is an iPad app that faithfully recreates the original Synclavier® Velocity-Pressure Keyboard button interface using modern touch-screen technology. Sync³ Remote communicates with your Synclavier³ installation using custom MIDI messages. The integration with the Synclavier® hardware is complete - touching a button on the iPad lights the button on the VK for example. The VK buttons are organized in two panels - one for Timbre design, one for controlling the Digital Memory Recorder. And, two - or more - iPads could be used simultaneously to set up multiple remote control stations within your studio. This latest build operates Synclavier³ using the Synclavier Knob attached to the iPad.
