MOTU released Digital Performer 9.5 with ZTX PRO™ technology: cutting-edge audio time-stretching and pitch-shifting DSP developed and refined through years of advanced R&D by the renowned engineering team at Zynaptiq GmbH.
ZTX PRO time-stretching has been deployed throughout Digital Performer 9.5 wherever you apply audio time-stretching and produces dramatically improved results, even when slowing down or speeding up audio by extreme amounts. You will experience state-of-the-art time-stretching quality on any type of audio material: drum loops, solo instruments, multi-timbral material, vocals, full mixes, mono, stereo, n-channel, etc. Easily conform imported loops and audio clips to your project tempo, apply wholesale tempo adjustments to entire mixes, create conductor track tempo maps (including gradual tempo changes) and many other operations that alter the length and speed of audio clips.
