Hi,
Just a quick question, where does validation of parameters belong?
Invalid params might crash the engine, so some validation should go there.
But if the job of validation is down to the UI, the engine can be more
efficient.
But if multiple UIs are possible, validation effort is duplicated.
How should I approach?
Plugins must gracefully handle out-of-range values, typically either by
clamping or ignoring. The ranges in LV2 are "soft".
There could be an extension for "hard" limits, as a micro-optimization,
but I don't know if one exists (or if the performance advantage of
avoiding an if or two is worth the hassle).
