Any MIDI keyboard controller will work for your needs. The keyword is "controller" meaning there isn't any on-board sounds. Many of these connect by USB to your computer which acts at the interface
and provides power.
A model discussed here from time to time is the Behringer UMX610 as the keys are more organ like verses a fake piano feel others try to emulate.
https://www.sweetwater.com/store/detail/UMX610 Other choices are the M-Audio Keystation, Nektar Impact LX61, and Alesis V61. These are also available in 49 note variants is space is a concern. They all have preset buttons that can be mapped to HW pistons or stops.
I would recommend that you try playing these or others and determine which keyboard action feels best for you. They are all different and probably not as nice as your current keyboards from Midiworks but then they are lighter, more portable with a lesser price.
