LFO Process frequency values are different in the inspector and in the widget.

The LFO process frequency values are in hertz (I empirically verified) in the widget and in some kind of strange scaling in the inspector.

I think they should be in hertz everywhere.

So for this issue I'd like to redo the LFO process in avendish as this grants better flexibility than the previous API this was implemented with.

I had started here : https://github.com/celtera/avendish/blob/3028a955d3489795848c389e8360ea0631b35989/examples/Advanced/Utilities/LFO.hpp#L12

The current code is there :

score/src/plugins/score-plugin-fx/Fx/LFO.hpp

Line 229 in a96d630

namespace v2

@guillaumeriousat would you be interested in looking into this ?

Looking into this could be fun. How much do we need to care about compatibility with older patches ?

[jcelerier]

so the compatibility mechanism currently is :

• Processes have a different UUID
• Processes can have a "deprecated" flag. If they have this flag, the user cannot create new instances of them. But they will still be loaded in a given patch
• So the system keeps in memory the previous versions of the process for compat with older patch, but if you create an object you always get the last version (which has a different UUID than the previous one)
• A next step would be to have something like Ableton Live's feature which allows to upgrade a process to its new version, I have some rough draft prototypes for how to achieve this
• For a PR it's ok to just add a new object (or continue the "LFO X" object shared previously)
