Input Numeric Values From Generic VST Plug UI

…hasn’t worked properly in years. When you switch a VST Plug to Generid Editor, you can -only- use the slider to change values. Again: typing values doesn’t work as it does in other numeric value fields in Cubase.

This is a problem with VST2 plugins format which does not provide a correct way to get from a string the correct associated normalized value.
VST3 plugins should not have this issue…
