Hi Peter, good news and bad news.
The actual operation of Auto Play works exactly how it should now you can use Auto Play while performing and not contaminate your preset playlist, but i have a visual representation issue with it, i am not sure if it can be fixed as it is rather complicated but here it goes,
In stop mode i programed my playlist songs 1,3,5 with Autoplay and played around to see what happens.
If you choose song 1 with Auto play enabled hit play now disable Autoplay the Button goes grey as expected but the autoplay arrow on that song does not dissapear temporarily to represent to what is about to happen, this is not great , what should happen is that the arrows in each song should allways represent the state of the auto play button eventhough after this once off autoplay happens the arrow should reappear again to its default stop setting when the next song is enabled, this way you are allways getting the correct visual feedback to what is to happen next. At the moment you have to rely on the Autoplay button only as the song arrows dont follow to what is actually going to occur.
This logic should be either way if you enable or disable autoplay while a song is playing giving correct visual status.
The actual operation seems to work well its the visual feedback that needs more work.
Cheers Damir

More Feedback
Chose a playlist in stop select autoplay on song 1,3,5 then turn on the Autoplay ALL in that playlist, now play song one through to song 5, you will notice song one has blue arrow next to it and autoplay button is also highlighted, this is correct, now when the second song plays which has a grey arrow next to it because it is a part of the ALL autoplay selection which is also correct, now the Autoplay button is actually grey which it should be blue as the Autoplay is still going to occur using the all autoplay selection yet this grey autoplay is now giving you the wrong indication.

I again suggest the Autoplay button and the arrows that appear in the song column should allways be in sync to truethfully represent to what is actually going to happen in the immediate next step.
At the moment sometimes you have to trust the autoplay button then sometimes you have to trust the arrows this is not correct.

Feedback on repeat Playing the same song.
It is a backward step not to be able to repeat play the now playing song as the next song, this actually almost worked perfectly and would be very usefull on stage if implemented correctly at least in playlist mode if it cant be done in Song mode.
Lots of times the audiance wants the same song again this would really streamline on stage capability when using foot pedals.

More Autoplay feedback something i pointed out a while back,
Autoplay ALL and Autoplay single button is present if you are in playlist mode with lyrics screen showing, this is good and useful, but when you close down this window as you need to edit your playlist you dont have the most important button present on that screen and that is AUTOPLAY SINGLE BUTTON which is the one needed to enable and disable individual autoplays on that screen, it is the more valuable button to have on this screen than the AUTOPLAY ALL button as this is a simple once off switch, so my suggestion is please add on the single autoplay button next to the all autoplay button so we can easily edit our playlist requrement in both screens.
When manipulating song order i allways close down the lyrics screen as i can see more songs at once and more info is on screen so i can better organize my playlist except i cant place single autoplays i have to change screens to do that.
If you cant fit both buttons at least give us the single autoplay button on both playlist screens as thats the button that we need to manipulate a lot of songs individually, the all autoplay button is a once off choice and can easily be on one screen only which is the open lyrics screen while performing it can be activated easily, while the single autoplay button is mainly needed while editing.

Sorry Peter , i am writing feedback as i am discovering things so its a bit random,
i just realised if i slide to left on a song in a playlist with lyrics window closed you do have Autoplay available there as an option.
OK my point is Why did you do that when in the lyrics screen open window you have a simple one button that is always present and easy to ingage to activate autoplay for individual song that is selected, why did you introduce a different system in the edit view, this slide method it clumsy as you could accidently delete your song, it also takes more effort to open up before making a choice instead of just hitting a single button thats always on screen . This slide method is not obvious cause i didnt know it was there and i think i have used this software long enough that i should have known this.

The reason i never used the autoplay slide to left method is because i found a much easier way and thats the single Autoplay button thats on the screen at all times and easy to hit whenever needed, thats probably why i never discovered or perhaps have forgotten the other method because its hidden and its slower and dangerous if i didnt have this easier way i would probably get use to the slide method in time but why not use the most efficient way when available.

My feeling is priority should always go to Autoplay button as this is a button you use when changing your performance method live at that moment you dont want Autoplay ALL to interfere if its present , if you hit this button it means you either want or do not want autoplay to occur, at the moment Autoplay all does have priority and it should not as you are in final control .
With autoplay all engaged i want to be able to override the now playing song using autoplay button and i expect the arrows to represent my autoplay choice.Now the autoplay all hogs control and does not allow you to manipulate the now playing song which is very limiting on stage.
I really think more effort should go in to fine tuning these inconsistancies and streamlining the ease of on stage use before introducing any more features,
Youve done a fantastic job to get so far with ST3 and we all apreciate it, incase i havent said it lately THANKS A LOT this is my no 1 program and the only reason i use Apple products as there are a lot cheaper alternatives but ST3 is not available on them.
