  • We recommend making NotePerformer your default playback template from Dorico's Preferences.
  • With existing scores you switch to the NotePerformer Playback Template from:

    Play ▸ Playback Template...
  • Instruments and Expression Maps are automatically assigned from our Playback Template.
  • Playback Templates was introduced with Dorico 2.
  • Opening the NotePerformer interface from Dorico reveals our own high-resolution mixer.
  • If you delete staves from the score, you can remove the lingering slot by clicking the instrument name and selecting Special > (delete slot).
  • Solo/mute, volume and reverb work globally across all NotePerformer instances.
  • Channels are automatically grouped and color coded according to instrument family.
  • Double-clicking restores the default value for a parameter.
  • Instruments have different pan defaults, reflecting orchestral seating.
  • Re-open NotePerformer's mixer by clicking the 'e' button next to the bank, in Play mode.
  • 'e' stands for 'edit instrument'.
  • Clicking an instrument's name in the mixer allows you to override the sound for that MIDI channel.
  • This provides access to sounds that are not mapped by your notation software.
  • Or simply for using a different choice of sound for a staff.
  • Or for accessing additional drum kits such as rock, brushes or electronic drums.
  • You may want to increase the unmeasured tremolo speed in Dorico, from the Playback Options dialog.
  • We recommend a setting of 1/8, which is slightly faster than the default setting of 1/5.
  • A slower tremolo speed may produce a measured tremolo rather than an unmeasured tremolo, with NotePerformer.
  • NotePerformer supports custom organ registration by inserting a MIDI CC message into the score.
  • Please use our online calculator to determine the MIDI CC message. You can find it here:

  • In Dorico, you manually enter MIDI controller values in Play mode by expanding the Automation lane for a track.
  • Please select the appropriate controller, e.g. "CC103", and draw the value into the lane using the pencil tool.
  • For more information on how to use MIDI controllers in Dorico, please consult the Dorico Operation Manual.
  • For reference, you may add custom MIDI CC events in Dorico, from Play mode.
  • This is done via the automation lane for each staff.
  • In the case that playback and sound assignment isn't working at all, Dorico's sound driver may have stalled.
  • Please review your Audio Device Setup, in Dorico's Preferences.
  • Try temporarily switching to another ASIO driver, and back, to reset the sound driver in Dorico.
  • Or alternatively, you may switch to a different Sample Rate, and back.
  • With a Rent-to-Own subscription, you will receive a subscription-related monthly email.
  • There's a link beneath "X Additional Payments of $10.75 every Month".
  • Please follow this link to manage your subscription.
  • This is how you update your payment details or cancel your subscription.
  • If installation on macOS fails unexpectedly, Apple's Installer application may have insufficient disk privileges.
  • Installing from a Dropbox folder is a potential cause.
  • Granting Full Disk Access privileges in System Settings resolves it.


  • On Windows, please install Dorico to a location having the word Dorico in the pathname.
  • Dorico may otherwise fail to load NotePerformer.
  • Multiple articulations at the same time is only possible with NotePerformer 3.2 or higher.
  • Additionally, if you open a document saved with an older version of NotePerformer, you must make sure that your document’s NotePerformer expression map is at least version 12. Please see our support article on how to update your document’s expression maps in Dorico.
  • Unison notes are performed solo, even when using different voices.
  • This is the expected behavior in Dorico.
  • We hope to see a workaround to this in a future version of Dorico.
  • Dorico may collapse grand staves to a single staff in playback.
  • If a single Layout ▸ Solo Player is assigned to multiple staves in Dorico, these staves share a common MIDI channel.
  • What this means is, all articulations unavoidably spill over to the other staves in playback—including dynamics.
  • Identically pitched notes are also collapsed into a single solo note.
  • If you want to maintain staff separation in playback, the rule is to use different Solo Players in Dorico.
  • Accents and marcato may be very loud.
  • We currently don't have control over accent and marcato playback, but this is simply a dynamic change governed by Dorico from Library ▸ Playback Options...
  • There may be gaps of silence between subsequent slashed notes.
  • This is a known bug/behavior. Instead of shortening the individual notes in the tremolo by 85% (default note shortening) Dorico performs a tremolo only for 85% of the note's written length.
