The board I use with my iPad and Amplitube 4. Connectivoty via BT is good, but only when I press the button to change a channel, it reacts too slowly, approx 0,5 sec, thars mean the latency is higher as is normaľ When you play and need to change solo channel, thats is a delay which is hearable ! In home training and playing good but in case of live performance it may cause a little bit problemˇˇˇ
