An option to remote control ST3 would be cool. Having the iPad close to the mixer and sending tracks as well as showing lyrics on a 2nd display (all this would already work) but the have just a small iPad or iPhone with Setlist and possibility to control the main iPad. Host/Client would just mirror the lyrics and would always require the host Pad either near artist or controlled via footswitch etc. But changing songs, start/stop tracks, volume up/down etc. would be cool if this could be done via ‚small device‘
