I just purchased a tc-helicon play acoustic. I was trying to achieve what the performer in this video was doing: https://youtu.be/u6_OLGgxYW0?t=66 To turn on harmony effect while inside the looper mode. It didn't work for me because once I'm in the looper mode, pressing "hit" button will cancel the looper instead of turning on harmony. So how did the performer do it in the video?
Hey Quan, Unfortunately you cannot control effects while in the looper screen without the help of an external foot controller. What's actually going on in that video is that the performer first exited the looper screen, then pressed the "Hit" footswitch again to enable harmonies. The video just didn't show the first press of her leaving the looper, sorry if it misled you.
