Celtic Sounds is a fully transposable MIDI sound module with seven traditional Irish and Scottish musical instruments: High-D Tin Whistle Wooden Flute Uilleann Pipes Chanter, Drones, and Baritone/Tenor Regulator Pairs Anglo Concertina Button Accordion Great Highland Bagpipes Chanter and Drones Scottish Smallpipes Chanter and Drones Every note on the instruments have been individually to provide a very authentic sound. The app is a CoreMIDI Sound Module for use with CoreMIDI file players and other CoreMIDI controller apps. You may also play the sounds using a MIDI keyboard or other MIDI controller attached to the device using a MIDI interface connected to the Lightning port. The app also works as an Audiobus 2 source module and is compatible with Audiobus 3. Inter-App Audio support is provided by Audiobus. Using the controls, set your instrument, transposition, volume, reverb style, reverb level, MIDI channel, and MIDI pitch bend values. Use the "Transpose Semitones" slider to shift the entire instrument up or down up to one octave in semitone increments. This setting shifts the pitch of the sound but does not change the MIDI note numbers the app responds to. Touch the number to the right of the "Transpose Semitones" slider to reset the transposition to zero semitones. Choose your reverb style and level from four options: Room, Hall1, Hall2, or Church If you have a MIDI "stuck note" touch the "Shhh" button at the top right to stop all sounds. The app responds to both MIDI note-on velocity and pitch bend messages on the selected MIDI channel. Set the maximum pitch bend response using the "Pitch Bend Semitones". Default is two semitones. The MIDI note ranges of the instruments are: High-D Tin Whistle - D3 (62) - D5 (86) Wooden Flute - D3 (62) - D5 (86) Anglo Concertina - C2 (48) - A5 (93) Button Accordion - G2 (53) - E5 (88) Highland Pipes - A3 (68) - Bb4 (82) Smallpipes - A3 (68) - Bb4 (82) When playing the Uilleann Pipes instrument, the following special MIDI notes, starting on C1 (36) are used for the drone and regulator sounds: Single regulator notes: C1 (36) - Bass regulator G C#1 (37) - Bass regulator A D1 (38) - Bass regulator B D#1 (39) - Bass regulator C E1 (40) - Baritone regulator D F1 (41) - Baritone regulator F# F#1 (42) - Baritone regulator G G1 (43) - Baritone regulator A G#1 (44) - Tenor regulator F# A1 (45) - Tenor regulator G A#1 (46) - Tenor regulator A B1 (47) - Tenor regulator B C2 (48) - Tenor regulator C Drones: D2 (50) - Lynch Drones D#2(51) - Crowley Drones Regulator pairs: E2 (52) - D/F# Baritone/Tenor Regulator Pair F2 (53) - D/G Baritone/Tenor Regulator Pair F#2 (54) - F#/A Baritone/Tenor Regulator Pair G2 (55) - G/B Baritone/Tenor Regulator Pair G#2 (56) - G/C Baritone/Tenor Regulator Pair A2 (57) - A/C Baritone/Tenor Regulator Pair Uilleann Pipes drones key triggers (D2 and D#2) are "latching" . The drones start on the first press of the trigger key, stop on the second. The Uilleann Pipes chanter notes start at D3 (62) and go to D5 (86) When playing the Great Highland Bagpipes and Smallpipes instruments, the drones, are triggered on receipt of D#2 (51) and are latching. The drones start on the first press of the trigger key, stop on the second. When playing the bagpipes instruments, any pitch bend messages received only effect the chanter notes, not the drones or regulators. The bagpipes instruments are setup for the default WARBL GHB controller note mapping for notes and drone switch. MIDI Transpose Control for use with MIDI Chanters and other MIDI controllers: Use the "MIDI Transpose Semitones" slider to shift the incoming MIDI note messages up or down up to one octave in semitone increments. This is useful for MIDI chanters or other controllers that have a fixed message range. Touch the number to the right of the "MIDI Transpose Semitones" slider to reset the MIDI transposition to zero semitones.
