I wrote a review on the Perform VK a few hours ago with the caveat that if I found answers to my technical questions I'd be back with a 5 star rating and here it is. The tech prob was me.My tap wasn't working because it was being controlled by the midi on my keyboard. Now I control bpm frrom the keyboard synth. Still very impressed with the sound quality I'm getting.The texture and flow of the vocals with harmony can be hypnotic when you get it right. Amazing tool I'll be using for a long time, unless TC comes out with something better.
