Maybe there is a problem with the new update 3.4.1. Another user reported something similar here: https://support.stagetraxx.com/d/718-st3-freezing-after-apparent-update
It would be great if I could reproduce the issue. I have just tried with playback of about 100 songs and it works fine on 3 different iOS devices. Could you provide some details:
- What iOS version are you running?
- Which formats are you files in? Do you have different sample rates?
- Do you have an audio interface connected?
- Are you playing multitrack songs?
- When you press stop, the button changes to the play button, right?
- What happens then when you select another song?
If I can't reproduce this today, I will roll back the changes of the 3.4.1 update and will try to get a hold of the problem in a test version.
