But if one still needs a hardware keyboard to control a software synth then that can get pretty expensive , not that a good workstation is cheap but then I might as well buy a workstation. Or did you guys mean that one should have a workstation and a software synth ?

Can a workstation on it's own not upload commercially available sample libaries ?

Also are the Fantom X , Motif ES and Triton Extreme really the best workstations or just the most well known ?
