GUIs are limited. The power of a library like Tone comes from being able to set any value you want,
|
||||
not just the predescribed ranges of a GUI. Instruments and effects can be created and set
|
||||
with object descriptions like the one above. Edit the values of the JSON descriptions for the score
|
||||
and the MonoSynths then click 'reload' to hear your changes.
