if you look at rojec posting replies ,,he stated that hes in favor for a better implemtation of auto play..this request and others has been on going for years ,,since version 1.25..on the inseption of Cross ,the devoplement was in stages and consideration for keeping it simple and DJ compatiable,,not saying it will not come about ,
due to my usage its not a great concern ,, but 100% understand where you are at with this,this area of improvement as well as a few others ie effects and wave form ,,are top of the list from users suggestion ,,not sure where there at on the dev teams concerns ,the most postive thing that can be done is clearly express you thoughts on changes you would like,to add to the ongoing suggestions to mixvibes dev team,
my work around is that i use a tablet with Cross DJ and uses the auto plat feature and mix/fade it in /out as needed..or just cue in a pre recorded set to fill the time needed
not saying this is best but get it done the few times nessary
