Great app and it keeps getting better

I’ve been using this app to play along with lyrics and chord prompts and it’s just brilliant. I have noticed now you can also use this app as a sound module for playing the midi instruments with a midi keyboard making this a really flexible. Using your own sound fonts is also a breeze.

Great app

Love the app only gave it 4stars because I can’t save the midi after I change the instruments, otherwise it’s worth it
Fast response back thank you
, with the iPhone app there is no settings, what am I doing wrong ?

Developer Response ,

You can save the edits but you might need to enable that feature:
Settings -> Player -> Save Options

Value for money

I bought this app to play midi files on my iPad with lyrics being displayed for live gigs. Works like a dream. Terrific support from the developer as well.
