I agree this is where Roland shines every time.....do some recording as an A/B comparison with the same sounds & you can HEAR the difference every time for sure.. this includes the G70 VH unit also.... this is why Roland can wait 10 years in between offerings on TOTL arrangers which dispels that "OLD TECHNOLOGY" theory..lol.....good luck to you....good to hear it from someone who actually has a T4 & a G70 side by side.
