Effects like a low pass or comb filter are included, as is a 3 band graphic equalizer with a kill function for fading your bass, mid and high sounds. There is a built-in sampler that lets you play your own samples, or choose from a selection or preloaded samples. You can change the playback tempo and pitch, cue up songs, match beats with a visual beat analyzer and preview a mix on headphones (if you have a sound card with two headphone outputs).
