There have been no changes in v6 above v5 relating to Novation Launchpad model support, i.e. the models that we have here, and for which Hauptwerk v5/v6 has full native support are the 'Novation Launchpad Mk2' and the original (mark 1) 'Novation Launchpad', as covered in this topic (from November 2020):

- 'Novation Launchpad Mk2'. If you're looking to buy a Launchpad then I would recommend getting this specific model.
Other models, such as the 'Launchpad Pro' and 'Launchpad Mini' series may - or may not - also work, but only the standard 'Launchpad' models (not 'Mini' or 'Pro) are officially supported. I'm not aware of a 'Launchpad Mk3' model existing at this point in time (only the 'Launchpad Mini Mk3' and 'Launchpad Pro Mk3', which we don't officially support.) If Novation do make a standard 'Launchpad Mk3' (not 'Mini' or Pro') to replace the current 'Launchpad Mk2' then perhaps we would look into adding support for it in Hauptwerk for some future version, but at that this stage that isn't applicable to my knowledge.

(Novation change their models rather frequently, and we have limited resources, but I expect we'll add support for one or more of their new models at some point in the future.)
On the Launchpad Mk2 (which I can recommend -- it's robust, with good-quality buttons and bright LEDs) the square buttons are 19mm x 19mm, and the round ones 14mm in diameter.
There was a topic on the Launchpad Mini Mk3 recently here: viewtopic.php?f=4&t=19559
