True. This *will* a separate API, and using it directly will

by far the easiest way, but
1. Given that basic LV2 is almost nothing, *any* extension

more or less corresponds to a complete redeifinition (with

only the run() call being standard). So it's not really

so special.
2. 'Embedding' it in LV2 may placate some people, and

save me some flames.

(b) is not provided by a basic get/set control port value

interface. How does the LV2 'external GUI' handle this ?
More generally, I don't think you can do automation right

by just monitoring/injecting control port values. Except

maybe when the automation data has a constant rate, e.g.

1/16 FS. In all other cases, it's only the plugin that can

decide in any intelligent way on control points, their

frequency and/or step size, etc. and it's only the plugin

that can interpolate such data in the correct way.

At least the compressor has other issues as well (didn't test the

others).
