My idea of use Milky as a DJ tool needs the following playback mode with these features:
1) A tab start to play when the play button is pressed
2) If other tab is playing, the new tab does not start to play until the current playing pattern ends.
3) A Xfade between the volume of these two tabs would make the mix between them better. ( a box/slider to select the amount of rows (X) to make the fade in and fade out would be nice.... X/2 row for the fade out X/2 for the fade in)
3a) The Xfade could be optional... so if you dont check it, when you play a new track when other is already playing.. the two tabs would play at same time and they would play in "row" sync. You would need to use tracks with same speed/BPM settings to not destroy the sync between them.
4) If a module ends in a tab.. the next tab start to play with a Xfade (This feature would allow people to load new tabs and prepare the session and the next songs to play). We could name this mode "jukebox"
5) A checkbox in each tab to "arm" them would allow you to play the "armed" tabs at same time with a single play song/pattern key press
