I have been a Windows OMB user for over 10 years now, And while it’s not the perfect piece of software, it fulfills a need that no other application comes close to. I have been waiting years now for this, or some other similar program to come to iOS, since I use the iOS music ecosystem for many of my musical creation needs. Now that it’s here finally, I am overjoyed, and have been playing with it quite a bit. It currently lacks though, some important functionality that has come to be expected with most iOS MIDI apps - namely, background operation (so you can operate it in the background with a midi keyboard - left hand - and use an onboard iOS instrument to play melody in the foreground - right hand) and IAA and/or Audiobus compatibility. Once these things are in place, I see this as being a very successful app. Until then, it will have limited use. But still way better than nothing!

For the price, I wasn’t expecting so many bugs. Personal styles made on the psr-s950 either don’t play at all or have parts go silent after I press the fill in. Same when changing variations. I don’t know if problems can arise when user style parts are empty, and there is no way to tell if they’re empty, unlike on the psr series there would be a light on available style parts. I love making my own styles and wish this app had more functionality like a mixer and IAA/Audiobus support. This app has the potential to become a really really great full blown DAW that professionals as well as beginners would enjoy and love. You have my full support in your continued efforts at improving this amazing app.

I bought this a few days ago and wanted to put some favorite styles in a new folder using the feature included within the app. You can make a new folder but you can’t copy or cut styles from a different folder and paste them into the new folder. This feature is described in the online help document but does not work. I’m using an iPad Air3 running iOS 14.6. I also tried this on my iPhone XR and same problem plus some other quirky actions and lockups.This is by far the best Arranger Keyboard app available however, it hasn’t been updated in 2 years! Please fix this problem and consider refreshing and bringing the app up to today’s standards.Thank You

There are many sample apps for ipad that you can use to play along with this app yet this app can't play in the background. It pretty silli that you have to stop your performance if you de ide to use a different sound from a differen app because this thing can't just keep on playing while you choose a different sound from another app. That's why only 3 stars.
