Currently we have a set of categories which apply to all expressive controllers (coloured red) e.g. hardware/software), and then some specific instrument/controller categories (coloured blue), used for topics which are specific to that hardware.
Generally, we will want to keep the number of categories low, since too many can get confusing for new users - so we are starting ‘minimal’ based on a keep it simple approach.
If you feel others are necessary, please post here suggestions.
as a side note… discourse supports ‘sub-categories’ , so if any particular category needs a bit more ‘organisation’, we have the option to create sub-categories.
