It uses Soundfonts for its samples, so it needs a Pc with Windows XP and at least 1 Creative Audigy ZS card, (Higher spec models require 2 cards) therefore if you like the sounds produced by Soundfonts, then you will like the sounds of the TMS system.
I would however recommend using a separate controller keyboard and double stand, (Not forgetting a desktop (Tower) computer) as the models shown look like very poor DIY disasters.
