I get that having analog stuff that you physically wire together, or purpose-built digital stuff with a nice interface, is "real" and tactile and fun and all, but have you considered the fact that there's nothing you can do with that stuff that can't be emulated with software?

IMO you should keep one MIDI controller keyboard and sell everything else until money is less tight. (And also get yourself a bicycle, BTW.)
