The option to change bass line

I really like this app but it would be great if there was an option to change the bass line pattern on the 1st and last chorus. The 2 beat feel is just not appropriate on so many of the songs. It definitely doesn’t fit when playing the melody of most bebop songs.
Other than that tiny annoyance I’m really enjoying the app!

Kind of Disappointed

I bought this app thinking the instrument parts sounded a bit more authentic than other app I had, so I went ahead and bought the additional 1300 standards for $20. Problem is, the changes for some tunes are WRONG, and there is no way to fix/edit it.
Not to mention, you cannot create your own chord progressions and time signature change.

Other concerns:
1) a limited amount of grooves.
2) bass line is weak and uninspiring so you need to play along with piano tracks as well(which are ok).
3)No direct help contact/costumer service unless you go to their website.
4) The app loads very slow and feels “heavy” and buggy.
5)The additional songs selection is pretty limited. Some major classics are missing, and there are way too many blues tunes and rhythm changes.

There is a lot of work to do to bring this app on par with iReal Pro app, however doll sounding and artificial feel the latter app has.

Issue with Keys

The track does not play in the right key. Says it is in F but track is playing in G. Is there a fix for this or am I doing sometime wrong.
