There’s no way for other people to comment on controllers, because their suitability depends to a very, very large extent on precisely what you want to do with them. If you provide more details on what you’re expecting to do, people might be able to offer you some useful feedback.
My desired use of such a midi controller is not specific… since I am new to this area I just want to experiment.
Anyway thanks for the clarification
I think the Ardour’s support and connectivity info on https://github.com/Ardour/ardour/tree/master/midi_maps is enough for my case…
