When I think about having keys on every single device it just seems like such a waste of space. In the ideal setup, couldn’t you own 1 single extremely high quality 73-note midi keyboard which has every bell and whistle weighted/aftertouch/etc and then use that to route to all your devices which are keyless.
In the studio setting this would save a huge amount of space, and allow you to buy even more gear. When I see pictures of studio setups and they have stand after stand of full sized keyboards stacked on top of eachother… it just seems so redundant.
I appreciate the idea that having a keyboard detached from the synth removes you a bit from the experience, but depending how you situate things I think it can work. At most having one deluxe midi keyboard in each area, preferably driving multiple keyless synths.
