Good but not great

I would have given this app 5 stars had it not been for the fact that when in use there is an interference noise which reduces the quality of the sound. Great if just being used for fun but not for professional use which is a shame because it does have some great qualities.

Why has it stopped working - please update!

You were one of my favourite apps- why have you stopped working - please get this fixed- I was able to make such wonderful projects - would like to again! The app itself deserves 5 stars and more when it worked- so why doesn’t it work now!?
