For the record, one demo is https://webaudiodemos.appspot.com/midi-synth/index.html

If I press the keys rapidly, I can get 100% cpu on my linux Z620. It's no wonder an Arm device can't keep up.

This app has a master effect chain consists of a waveshaper, a compressor and a convolver. This effect block alone is not trivial for the low-end device.

Also the synth supports full polyphony (limitless multi-voice) and each voice is built with 2 OSCs and 1 biquad filter. Pressing 10 keys at the same time will trigger 20 OSCs and 10 filters, which is not a trivial task at all even on a moderately powerful device.

This issue is about a demo app on a low-end device. Do we need to keep this entry on the chromium issue tracker?

I am closing this issue because of the lack of activities. Also the issue is about the external demo page, not the WebAudio code in Chromium. Please re-open the issue if needed.
