Hey Mike, I don't have the fancy sound card system to listen [detail] that close to the MP3's..But I do have the real deal[G70] and I positively know there is no contest between the Yamaha harmonizer and the Roland harmonist...The Roland is far superior... [I am serious..play them both, I have!!)...

Oh , and thanks for reminding me ...the Tyros "lifeless" sound....just doesn't work for me....Personal opinion..Yes.

I thought maybe other honest opinions would have been posted by folks that have used both...I know I have never talked with anyone that thought the Yamaha harmonizer was better than the Roland [after playing both]...

As it has been said..Play what makes you happy...
