User Guide

VirtualDJ provides a simple, yet complex; interface for optimizing performance to the capabilities of the

computer based on its specifications. Depending on the system’s resources, some settings will work

better than others. It is recommended that you take time to adjust these settings to find the

optimum setting for your system.

NOTE: When new components (controllers, soundcards, external drive, and software) are added to the

system, performance options may require changing to achieve a new best possible performance based

on the additions or changes to the system.

Presets

Use this slider to select different preset configurations for the parameters below. Shift the “Presets”

slider to the right for “Best Quality” of sound, or shift the slider to the left for “Fastest” performance.

NOTE: Not all systems are able to handle the HIGHEST setting for “Best Quality”. It is highly

recommended to start at the “Fastest” preset and work towards the “Best Quality” setting testing

each setting.

Soundcard

Latency – the amount of time it takes for a device to respond to a command. Latency makes a

significant difference when using timecoded vinyl, CDs, MIDI or external control devices. The lower the

latency setting the more instantly the software will respond, but the more likely you will hear glitches

and pops if your computer is not fast enough to process the audio.

NOTE: in ASIO mode, some soundcard drivers don’t work well with a latency forced by the

software. In such case, use the “Auto” value (as pictured), and set the latency in the

soundcard’s control panel.

Safe Mode – When using a DirectX mode setting (like Simple, Dual, Mono or 4.1), VirtualDJ is less

likely to produce glitches and pops if your CPU is momentarily busy. The performance trade off is

scratching and pitch adjustments will use more CPU, especially with advanced algorithms. So, if using

advanced Master Tempo this will probably need to be disabled, unless the computer is very fast.

NOTE: this option has no effect on ASIO or Low-Latency modes
