Software Description

Quad is an open-architecture DVS (Digital Vinyl System) that can be used to play & scratch up to 4 MP3s simultaneously, controlled by 1 to 4 turntables. The turntables can be connected to any soundcard (ASIO driver required on PC); thanks to Quad's internal software Phono preamps it is even possible to connect the turntables to Line Inputs on the soundcard.


Open architecture:

  • Compatible with any soundcard (Windows: ASIO driver required).
  • Software RIAA Phono pre-amplification allows connecting turntables directly to Line Inputs on the soundcard.
  • Nearly every parameter is MIDI controllable.
  • Totally configurable audio routing.
  • Easy MIDI Learn.
  • Compatible with nearly all MIDI Controllers on the market (accepts CC & Note On/Off MIDI messages).
  • MIDI feedback for endless rotary MIDI controllers or motorized fader MIDI controllers.
  • Resizable and completely user-configurable GUI: Channels may be shown/hidden, EQ/Filter/asf. may be shown/hidden.

Total control:

  • 1-4 decks may be used to control 1-4 tracks (MP3s/WAVs).
  • Custom Vinyl Tracking algorithm provides a near-analog scratch experience.
  • Perfect tempo-synchronization of up to 4 tracks using SYNC.
  • Powerful 1-deck support (one single turntable may be used to mix up to 4 tracks).
  • Virtual Zero Lock Range makes pitch 0 really 0 and virtually eliminates the "resting point" at pitch 0 on old turntables.
  • Recording the mix as .WAV during mixing is possible.
  • Keyboard shortcuts allow using Quad without touching the mouse.
  • Preview Player for fast pre-listening of tracks on Headphones.

Advanced sound processing:

  • Fresh sounding filters (X-Filter, SVF).
  • 3-band Equalizers with parametric mids from 100Hz to 10kHz.
  • Tempo-matched FX (Flanger, Phaser, Echo, Delay, LFO Filter, ...).
  • Tempo-matched Loop Samplers.
  • Any audio material (real Vinyl / CDs / Mic / ...) may be routed from the soundcard's inputs into Quad for mixing and FX-processing.
  • Crossfader with 3 curves.
  • Support for VST plugins (Windows only at the moment).
  • Look-ahead limiters on each ASIO output avoid audible audio distortions when signal becomes too hot.

Managing your tunes:

  • New, improved browser.
  • ID3 Tags are editable.
  • Create cases of your favourite tunes and music styles.

  • fixed: MIDI In would not work correctly if multiple MIDI Inputs were selected
  • fixed: (OS X only) Quad would not play files with non-ASCII characters
  • changed: no license file needed anymore to unlock Quad
  • changed: instead of displaying a window to warn when loading a new song, a message is displayed in the Channel itself
  • changed: instead of pressing "L" key, you have to press Enter key to load a song
  • changed: instead of pressing SPACE key, you have to press F11 to tap. It works everywhere, also in Search Box.

  • added: completely rewritten database and search function. Displays results while you're typing and always searches whole database. The new database can hold metadata for any kind of audio format.
  • added: new EQ-type called "Isolator", inspired by some very good DJ mixer brand we won't name :)
  • added: AU/VST support in FX section on OS X
  • added: SYNC state of each Channel is now stored on exit of Quad and loaded back again when Quad restarts

  • added: pressing F1/F2/F3/F4 activates/deactivates Cue2 for Channel 1/2/3/4
  • added: in Search Box, using UP/DOWN/ENTER may be used to navigate through the songs without leaving Search Box
  • added: knobs are now greyed out when not used (when Filter X-Type is active, or EQ ISO-Type is active)
  • added: "Invert Phase" option for inverting Phono input phase for being able to use cartridges Shure M-44 and Stanton 500-II

Do you need to buy a soundcard?

Or do you get provided with one?

Re: Soundcard?

Unless you currently have the required soundcard installed on your computer you'll have to go and purchase one yourself.
