What's New

Fixed: Red buttons to learn playing accordion were not shown on iPhones with newer iOS versions.
Info: You must press the yellow "test" buttons more than one second to see the buttons red highlighted on some newer iPhones, because the buttons are near on the left/right borders.

App Description

Please look if the App "AAccompanist" will not match better for you. "AAccompanist" fully includes this "AccordionPlus".

Please contact me by mail. I can't help and reply, when you write only an App store comment!

You can map General MIDI instruments to sounds of the "Sound Canvas" App or the "Gwerder X4" sound module.

To improve sound quality, use an external Sound Module or for example the App Roland "Sound Canvas". All instruments of the "Sound Canvas" (SC-8820) are selectable. You can map all 128 GM instruments to other SC-8820 instruments.

Even better! * * * * *

So, this update took a great app and added the B-griff or B-system layout for no extra charge. And while not new, it is very easy to customize the sound by adding a soundfont of your choice and adding extra styles of accompaniments via midi files. Great fun!

What a marvelous app!! Wow!!! I am absolutely pleased.

Known problems:
- In iOS 7 there is a function called "Multitasking ...". Please set the switch to OFF (in iPad, Settings, General).
- No sound: Is the silent switch set to OFF or volume too low?
