DJ-1800 v3 introduced a new Pitch Lock feature. Pitch Lock dynamically resamples your audio tracks to play the audio faster or slower without a noticeable change in pitch.
Pitch Lock is a processor-intensive feature, and as such DJ-1800 offers several different quality levels for Pitch Lock. The default setting is to offer a Pitch Lock quality of Medium, which uses a spectral algorithm to dynamically modify the pitch. If you find that your computer is struggling to play multiple tracks at Medium quality, then we would recommend trying Low quality instead, which uses a less intensive time-domain algorithm. If this is still too high a load, then you can turn off Pitch Lock altogether to reduce processor load. As a general rule, if you are experiencing distortion or audio dropouts when playing audio in DJ-1800, it is highly likely that this is caused by your Pitch Lock settings. Try lowering the Pitch Lock quality, or turning off Pitch Lock.
You may also find that using an external hardware mixer with DJ-1800 (in either the "Mono Thru" or "Multi Thru" output modes) will help to reduce the processor load caused by Pitch Lock, compared to using DJ-1800's internal mixer (in either the "Mono + Mixer" or "Dual + Mixer" modes). This is because using DJ-1800's internal mixer requires DJ-1800 to play two copies of the audio (one for the master output, and one for the headphones output), whereas using an external hardware mixer only requires DJ-1800 to play one copy of the audio.
With so many different hardware configurations and system specifications available, it is very difficult to make a guaranteed recommendation as to what system requirements are needed for a particular Pitch Lock quality setting. We would always recommend that you download the demo of DJ-1800 and try it with your own hardware configuration before registering. The demo of DJ-1800 is fully-featured, and the only difference between the demo and the registered version is a 30-minute demo timeout per launch. As a result, the audio performance you experience with the demo is the same as you will experience once registered.
