KLANG:app vs VirtualDJ

KLANG:app is the control interface for KLANG processors, bringing setup, mixing and signal placement into one app. Each musician can adjust an individual sound mix. Users can position instruments around the listening space, including above or below the listener’s head, or use conventional stereo. Mixing tools include faders, panning, system settings and graphical 3D and i3D orbits. The app connects to processors over Wi-Fi or LAN and can manage one mix per device or all mixes from a single app. An offline editor and demo mode are included. Console integrations cover DiGiCo SD and Quantum, including mix-parameter control and snapshot recall, and SSL Live, with two-way control of faders, panning, mute, solo and tone filters. It also communicates using Open Sound Control and supports MIDI MCU and MIDI for Allen & Heath consoles. KLANG:app is free for supported devices, with no free trial, and runs on Android, iOS, macOS and Windows.
