Marcus... simply substitute Roland or Korg for Yamaha, and you may see why something like this is so good... You like your T5, but maybe you'd like to play some Roland styles or Korg styles into it?

Sure, you can buy EMC software, do all the converting yourself, deal with drum maps and non-standard sounds and features, or you get vArranger, and have it do all that for you, in realtime!

This thread concentrated on ONE way of using it, using Ketron or Korg sound sources to play Yamaha styles. But there's no reason (if Dan has the maps working) why it can't go in the other direction, depending on the Tyros's capabilities.
