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.

WARBL and WARBL2 are plug-and-play USB (and BTLE) MIDI wind controllers that allows the traditional musician to practice with headphones using familiar playing techniques. Designed to simulate a variety of open-tonehole wind instruments such as tin whistles, flutes, and bagpipes, WARBL has optical sensors and real toneholes for continuous finger sensing and realistic feel. An air-pressure sensor allows playing with breath or a bagpipe bag. WARBL does not produce any sound on its own. It is designed to control hardware MIDI sound modules or MIDI sound module apps running on an iOS device, for example AppCordions "Celtic Sounds" or Roland Sound Canvas. The WARBL Configuration Tool allows complete control over the air pressure sensitivity, vibrato/pitch bend, expression, and many other settings. You may adjust and save settings to design the instrument of your choice. The WARBL supports saving three preset instrument configurations, for example, Whistle, Uilleann Pipes, and Great Highland Bagpipes. The buttons on the back of the WARBL may be programmed to switch between the instrument preset configurations, change the octave, send MIDI messages, and many other options. To use, just plug in your WARBL to an Apple USB Camera Adapter connected to the Lightning port on your device, run the app, touch "Connect WARBL" at the top of the control panel and begin configuring your WARBL. Or if you have a WARBL2 with BTLE, press the BT MIDI button on the navigation bar to manage the connection to your WARBL wirelessly. When connected, the status at the top of the page will show "WARBL Connected" and you'll see MIDI event information on the display. Touch the yellow “info” buttons for instructions on using each section of the Configuration Tool.
