UilleannKeys for the iPhone is an expressive, authentic sounding concert pitch 3/4 set of Uilleann pipes (Irish Bagpipes) chanter, drones, and two regulators in the form of a standard two octave piano keyboard. It plays the four most common keys for the instrument of D, C#, C, and B.
Touch the drone puck image to switch the drones on and off.
Touch the keys to play the chanter notes.
Touching in the upper half of the key plays the note at standard pitch. Touching lower on the key plays with the pitch proportionally lower to allow for pitch bending and vibrato effects
Finger vibrato for expression, as is done on the real instrument, can be added by sliding back and forth along the length of the chanter keys. The note C has an extended pitch bend range as typically used when playing a real chanter.
Play the regulator chords by touching the four squares above the keyboard on the left.
The chords match the tenor/baritone regulator pairs and are:
Since the real Uilleann pipes chanter doesn't play below D, the two regulators for chords may also be played on the upper and lower halves of the C and C# at the bottom of the keyboard.
Touch the mixer icon at the upper right to bring up the settings page where you can select the key (D, C#, C, or B), set the volumes of the chanter, drones, and regulators, set the amount of drone chorus effect, and overall reverb level.
Play along with the music on your iPhone by playing the track and then launching UilleannKeys.
