Hi Peter, just playing around with iPhone remote i noticed something when using MIX on a button , my START/PAUSE button IS PLAYING I CAN MIX to next song while its playing and thats fine but if i PAUSE the song using Stop button then i hit MIX this actually also just STARTS the song and the next hit on this button becomes a MIX to next song, this is unusual behaviour as the song should only start when i hit the START button and not if i hit the MIX button as nothing is playing.
I know its not a big deal as its not a major issue if both START AND MIX START THE SONG AGAIN BUT ITS NOT THE CORRECT LOGIC, i am sure we can live with it but i thought i would mention it in case it is a bug that might create a problem for some users.
My midi setup on iphone is using control change 20 for start/pause and CC27 for MIX button they both work but MIX also Starts a song if its paused.
