Cubasis 1.7.1 maintenance update available now!

Thanks for the update, still have lots of audio problems, popping, cracking, out of time no idea what’s causing this no other apps running no IAA Ram empty (as much as I can) space on ipad 2gig? Any ideas on how to rectify as never had this problem until newer updates 1.7. Also now when I quantise midi notes all the notes disappear only happens on the first 1/1 to 1/64 the dotted and triplets work fine, I really like cubasis but I’m finding it increasingly more frustrating to use, so many bugs, the audio being the main problem. Please help.
Using ipad3 with latest ios 7.0.4.
