I use my Ipad with the App OnSong for Note-sheets and also to change the Presets from the Helix Floor. When connected with the usb-cable and the camera-adapter from the ipad it works perfectly. The Helix receives the bpm from the App and the delay works. Then I wanted to get rid of the cable and found the wireless adapter from yamaha MD-BT01. Connection works and the presets also change - BUT the tap tempo is very irregular. Some information comes, but not nearly in time. And so the delay always skews the tone so i can't use this. Does anyone have an idea? thanks for your help!
