I use and swear by this: https://www.sweetwater.com/store/detail/KeystepPro--arturia-keystep-pro-37-key-controller-and-sequencer Involves NO modules, which opens up more potential space. I also have two BSPs that can be locked up to that, and then I can also lock those to the DAW either with CV Tools or sending a MIDI clock. So, nah...you don't need those modules for this purpose.
