My Tyros 4 is now my gigging arranger that replaced my Tyros 3. Love the SA2 voices, the new choir/ vocal voices, and depth allowed in both the Voice And Style Creator.

The Tyros 4 flash memory was a huge improvement over the T3 DIMMs. Had to wait up to 20 minutes for my Custom and Expansion voices to load each time I turned on my Tyros 3. Those days will be over when my Tyros 5 comes in.

So if no more arrangers were made I would be abundantly satisfied with my Tyros 4, and pamper my backup Tyros 5 that will remain in my home/studio unless an important occasion warrants playing out.

I invested my time and energy learning the Yamaha OS, but any major manufacture makes a very good arranger to satisfy ones needs far into the future. Have to remember that these modern arranger do wear out and age, so I keep two at a time and trade up the oldest model every three years or so. For live performances your arranger must be dependable and must help make sure they remain dependable as possible.
