Bug with the "sessions" feature.
When opening a previously saved session - it comes back in a different BPM...
it happens to me most of the times when i open a saved session.
I use ipad mini2 IOS 9.1 with audiobus and amplitube.
Do you have any other Link-enabled apps open? This is probably related to the default in the latest version of Loopy to the Link BPM instead of the saved tempo. Link is saving your tempo from whatever else you worked on before opening the saved session and applying it to the session you just opened.
