Claviro Organ

Your pipe organs, played on iPad.

Claviro Organ opens the GrandOrgue sample sets and the unprotected Hauptwerk-format sample sets you already own, and plays them from an iPad and your MIDI keyboards. You don't need a computer under the console.

OPENS THE SETS YOU OWN
• Import a set as its maker ships it, one .rar, .zip or .orgue file, or its folder, from the Files app, iCloud Drive or a USB-C drive.
• Patches and add-ons go into the organ they belong to.
• Before anything is copied, the app shows the stops, keyboards, console pages and space needed.
• Keep the samples on the external drive if the iPad is short of space.
• Stops, couplers, tremulants, swell boxes and pistons come from the set itself.

PLAYS THE LARGE ONES
• Samples are prepared once on import, then read from storage as you play.
• Large organs load stop by stop, so sets of several gigabytes play on an iPad with 8 GB of memory.
• Mono mode halves the memory for the very largest organs.

THE CONSOLE, AS ITS BUILDER DREW IT
• The set's own jambs, drawknobs and tabs, page by page. Choose which pages to keep.
• The builder's combinations appear as real pistons. Sets without them get P, mf, f and T.
• Eight memories per bank and as many banks as you like, exportable as a file.

MADE FOR THE SERVICE
• The Music Stand: your PDF scores, with the registration bar below the music.
• Page turns from a MIDI foot pedal.
• Map any MIDI button to memories, stops, couplers and tremulants.
• Slide Over and Stage Manager show a compact registration panel beside another app.

SOUND
• 44.1 or 48 kHz, adjustable buffer, up to 4,096 voices.
• Convolution reverb, including your own impulse responses.
• Six historical temperaments besides equal temperament.
• A safety limiter so the full organ never clips.
• Record what you play as MIDI.

WHAT YOU NEED
• iPadOS 16 or later. 8 GB of memory is recommended for large sets.
• USB or Bluetooth MIDI keyboards (optional; an on-screen keyboard is included).
• Sample sets from their producers. Many excellent ones are free, and Lars Palo's Bureå Funeral Chapel is included as the Claviro Demo Organ.

Encrypted (copy-protected) Hauptwerk sets are not supported.
