AccordionGCF and AccordionFBbEb are authentic sounding, easy to play, standard 31-button three-row tuned Button Accordions for the iPad.

GCF (SOL in Espanol) and FBbEb are very popular tunings and used in many styles of music including Tex-Mex, Zydeco, Mexican, Tejano, and Conjunto.

On the GCF version, the instrument has a G scale on the bottom row, a C scale on the middle row, and an F scale on the top row.

On the FBbEb version, the instrument has a F scale on the bottom row, a Bb scale on the middle row, and an Eb scale on the top row.

The button layout is based on the most popular standards used for three row instruments with additional accidentals at the top end of the rows.

The app uses the same fingerings and has essentially the same button spacing as a real instrument.

The built-in note guide will help you quickly learn your way around the buttons.

Here's how to get started playing tunes:

The app can be played either with the iPad on the lap or held vertically like the real instrument.

Touch the buttons with the fingers on your right hand to play. Buttons light up in green when touched.

Multiple buttons may be pressed at the same time to play chords.

This style of accordion is diatonic and plays different notes depending on whether you are pushing or pulling on the bellows.

Touch the anywhere in the bellows image at the top of the screen for PUSH notes, lift your finger for PULL notes.

The PUSH/PULL indicator shows the current bellows direction.

Starting with version 1.1 of the GCF version, and on the FBbEb version, you may select between dry or wet tuned reed sounds.

Adjust the Volume slider as desired.

Touch the ? icon to show the note names. The note names change with the bellows direction.

Touch the i icon to bring up the help screen. Touch anywhere in the help screen to go back to the play screen.

All settings are saved when the app exits.
