The Hohner SqueezeBox Pro app allows musicians to practice chord combinations, scales, and songs on-the-go. Practice in headphones, or plug into amplified speakers for live performance.
The app supports both Audiobus and Inter-App Audio for use with GarageBand and other multi-track recording apps.
Simply touch in the bellows area to toggle between bellows push and pull, then play on the buttons.
Since you may want to play chords with more than 3 or 4 fingers, you'll need to turn off "Multitasking Gestures" in your iPad's Settings, under General/Multitasking Gestures.
Touch the sliders icon at the upper right side of the screen to bring up the controls where you can select the tone (EAD, FBE, GCF, ADG, or BbEbAb), choose between M and MM reed sounds, and control the volume and reverb settings.
Touch the "?" to cycle through the note tab and note name label styles.
Touch the "i" button to bring up the help screen.
Touch the "Tabs" button at the top to bring up the list of song tabs.
Touch the "T" button at the the top to show/hide the song tab display.
All settings are saved when you exit the app and restored the next time you run it.
This app is ideal for the beginning student or professional musician who needs a simple carry-on companion to compliment his or her actual accordion. While not meant to be a replacement for a real accordion, the app is a convenient and easy tool for practicing, learning, or teaching.
