1. There is no limit to file size if that is what you are asking. Having a much larger file could cause that file to take longer to load, but I doubt it would be significant.
2. Try opening the metronome, tap the settings icon and enable the option to prevent delays while starting the metronome. That setting also impacts audio playback, so it could help prevent stutters.
3. About the only thing I would suggest trying is to go into the audio player settings and uncheck "Use advanced audio player". You can see if the default OS audio engine works better for you.
4. There is a track list setting to use tracks from all songs in the entire setlist. You would also need to uncheck the option to change tracks with the current song. You can then change songs in the setlist and it won't change the audio track. There is no setting to allow audio to keep playing while you load another song though. I'm not going to support that as it opens up too many problems. Other users have asked for an option to require a confirmation before loading a song. I am considering adding that when time allows.

The Android version has been around longer and is more battle tested, so I would say that is overall more stable. The iPad version seems very stable overall though. I'm not sure when you say "capacity for audio", what you really mean, but the two should be about the same when it comes to audio playback. I don't have enough experience with Apple's audio engine to know whether it performs better than the OS audio engine on Android.

Hi, 

thank you for your answers! Next week I try your advices. 
I just want to add one explanation - when I write about capacity, I ment overall capacity of the program. How many  GB of audio program handles. For example I have more than 700 songs in the program and almost 400 audio files. So my aswer was about this - Is safe for stability to continue add more audio files?
When I make backup, it has more than 15 GB. 

Thank you
