Hell there ! I need a controller to use transport comanda and also use solo bottom.
Do you want a controller that just does those things? There are plenty of keyboards that have that pretty much built-in . There are so many options.
I’ve got plenty of gear that has those options.
I use my computer keyboard and piano keyboard x2.
Also a Contour shuttle and a stream deck, trigger finger and my daw controller. I have an app on my phone too.
A bit more info might help.
