How to implement MIDI player of MIDI.js for notes sequence

I am using MIDI.js in my project, here is my code for playing sequence of MIDI notes

for (var repeat = 0; repeat < melodyrepititions; repeat++)
        {
            for (var i = 0; i < composition.length; i++)
            {
                for (var j = 0; j < composition[i].length; j++)
                {
                    if (composition[i][j] != 0)
                    {

                        MIDI.noteOn(0, composition[i][j] + scale, velocity,delay );
                        MIDI.noteOff(0, composition[i][j] + scale, delay+onlynotationsofeachbeatbracketdelay[i][j]);
                    }
                    else if (composition[i][j] == 0)
                    {
                       MIDI.noteOff(0, composition[i][j] + scale, delay);
                    }
                    delay = delay + onlynotationsofeachbeatbracketdelay[i][j];
                }
            }
        }

I want to implement MIDI.js player for this sequence to start,pause,stop the melody while playing. I am not able to figure out how can I use MIDI.js player functions for such sequence. Please guide.

use https://github.com/surikov/SSSynthesiser.js instead of MIDI.js.

SSSynthesiser.js has full controls over what is playing. You can change in realtime all instrument samples, melody etc.

Update

this is old answer.

Use https://github.com/surikov/webaudiofont instead of it.

Read docs, look to examples. See example for MIDI-player here https://surikov.github.io/webaudiofont/examples/midiplayer.html

I think it is not possible to implement MIDI player directly to sequence of notes, so solution I got is, one need to convert sequence of notes into MIDI file & then you can input MIDI file to player. Here is link which gives more details on conversion of MIDI file

Library which helps to convert sequence of notes in MIDI file https://github.com/sergi/jsmidi
