Scratchy sound is the main problem when the system ressources are limited. Here the ressources used are the ones of the web browser.
You may consider trying these optimisations below in the same order that they are presented if you encounter sound problems.
Desktop/Mobile ressources are limited. Close any other application or browser tab.
Browser ressources are used to produce sound so the lightest browser the better.
Safe Button is recommended to make a fresh start without loosing any precious settings.
Disable Reverb first if not needed.
Disable EQ too if not needed.
Polyphony is crucial so the less tracks the better.
Free Usage for experimentation is the spirit here.
No Commercial Use by any other parts.
Donations are welcome, use the link provided at the bottom of the page.
Collaborations are welcome too, feel free to share and send us temperaments or MIDI files to add.
