Commands:

NB! All setXXX functions return current setting when called without parameters

 window.mms_embed_controls = {
       toBeginning, // Scroll cursor to beginning. Optionals ‘section’/’part’, default chooses which based on pos
 
       hasRecording: // returns true when ‘matched’ is an option
       setPlayTrack: // either ‘etalon’ or ‘matched’
       startStopPlay: // Start/stop playback
       
       infoModal: // Display exercise information
 
       partModal: // Display part choice modal
 
       getPartInfo: // Returns info object { default_bpm: <int>, has_backing: <bool> }
 
       listParts: // Returns a list of part names
       setPart: // Sets the current part (NB! Needs time to load again)
 
       tempoModal: // Display tempo change modal
       setTempo: // Sets tempo. Values allowed are from 0.3 (30%) to 3 (300%)
 
       sectionMarked: // Return whether a section is selected
       markSection: // Start marking a section from cursor position
       resetSection: // Reset currently selected section
 
       setRecordBacking,  // Set the mode for recording:  'none'/'backing'/'metronome'
       setPageTurnMode: // Set "just page turn" mode value - true or false
       startStopRecord: // Start/stop recording
 
       setFeedbackMode: // either ‘simple’ or ‘advanced’
       getFeedback: // Returns feedback object (see below), or null if it is not available
           // Feedback object is guaranteed to have: { score: <total score> }
     };


Events:

You can also register a listener callback to certain events via an "on" function. Currently three events are available: mms_embed_controls.on(‘<evt name>’, callbackFunction);

  • ‘fully_loaded' - all required assets loaded. Fired both initially and whenever part changes.
  • 'changed_part' - user has chosen a different part in a multi-part exercise
  • 'feedback_available' - feedback is avaliable, i.e. an attempt was just finished. Fired whenever recording stops.
  • ‘play_end’' - audio playback stopped, either automatically or from ui
  • ‘changed_active_track’ - switched between ‘etalon’ and ‘matched’. Query setPlayTrack() to see current
  • ‘modals_showing' - at least one modal open
  • ‘modals_cleared' - all modals closed
