The video you showed me, is the KEY TUNE function.

The Style is not SYNC with a wav, or vice-versa.

This is simply the wav running at the same BPM tempo.

You need to push the KEY at the same time of your beat, if not, it will not SYNC.

The Pa2x can SYNC to the beat of your style.

Is a PAD(in Korg), or KEY TUNE(in Audya).

But... in Audya, using the USER AUDIO DRUMS! you can now SYNC WAV's of your Style

You can assign one WAV for any part of your Style

Intro, Ending, Arranger, Fill, Break... so, up to 18 WAV's in one Style.

see the final of the video...
