With my Sweet Midi player I'm able to use a foot switch on my Alesis IOdock and start / stop midi songs with the IPAD in the dock. It would be great if option of the same was on the IRealb app.
are you meaning you want the song to play instantly when you press play instead of waiting for it to compile the song, count then play? and this for any song you choose instantly?
Otherwise it is possible to press 'play' to pause it just after the count, so it is loaded up ready for playing from the beginning, then press play.
