Problems in work and system

recently, the program works not correctly,lots of bugs and lag in the sound system.
after you save the project appears dull sound that spoils the project in the end.
Correct the errors and import and export music and the project itself.
The app gives an elegant but huge failures in the past which does not allow to work on it.
And make a Mac version
