Ways to prevent the browser from deprioritizing midiJS tasks in inactive tabs

[akashagrahari]

I have an application which plays notes in sequence taking numeric cues using the MIDI.noteOn and MIDI.noteOff methods. The frequency in which the notes are played drops drastically when I move to another tab. Is there a workaround to this?

Just to clarify. I am using the setTimeout method to create delays between sounds.

You can do it by using a worker thread to do the scheduling. Check out the example application at https://github.com/cwilso/metronome. I have been experimenting with this to schedule midi.js events and it's working much better.

@hmoffatt could you please post some code sample for implementation of web worker in MIDI.js

I'm won't have a chance to share anything for a month at least.

I rewrote the whole scheduler. It depends on a web worker for accurate timing.

However I don't think it's compatible with the audio tag output method, which could be removed (only internet explorer needs it and I don't think it works very well anyway), or the scheduler could be moved into the output methods too.

I have no idea if it would work with webmidi. Does that output method actually work?
