Put simply, Cubasis is completely non-functional on my (new) 12.9 Ipad Pro IOS 15 when I use bluetooth headphones. This has been discussed below, but it took me a while to find it the thread, and it is such a showstopper it needs to be flagged.
In detail, I installed Cubasis 3.3.3 on my brand new IPad Pro. There is no headphone jack on this IPAD, I used bluetooth headphones. Even with the simplest of all setups, a single looped MIDI track using the default piano, I found the following:
- metronome running very slow
- metronome running when switched off and playout stopped
- metronome beats every few seconds (at 120bpm)
- playour of midi notes erratic, missed notes, note pileups at the end of a loop
- freezing during playout
- app crashes
I tried a lot of things before I discovering that all I had to do was disconnect the headphones (multiple pairs tried) and Cubasis worked fine.
I was about to ask for a refund, but luckily I now have a fix (no headphones) and I have ordered a USB-C audio jack as an interim solution.
I do hope this is fixable. It makes a very bad impression indeed.
