Good the click will work for you!

There are 50 built-in playback styles and currently 12 blues (IAP) styles. Each style has a variety of instruments to choose from (in the mixer, just as you have used the click for drums). We have a list of other styles we will be adding in the future. Each style plays in the various time signatures (with a few exceptions) and this takes a considerable amount of time to prepare.

iReal Pro forms a nice basis for exporting a song a few times in different styles, cut/paste and adding drum loops for a final audio file while adhering to your chords and form you require.

We have plans for various new features into the future.
Thank you for supporting iReal Pro and your comments.
