Yes, that is the frustrating thing. While I love Tyros SA2 voices for Trumpet, Guitar and Tenor Sax there are other voices on Tyros I do not like at all. The Alto Sax is terrible, Electronic Pianos just OK, the Cello and Violin are also terrible. String Ensembles just OK with the exception of Live Strings being pretty good.
I have listened to many Arranger demos and tried many in stores and the sounds are all over the place. As I mentioned I like the overall sound of Roland Arrangers. They have the warmth of the Yamaha's but with a much livelier sound but also like Yamaha and Korg they have specific sounds I do not like. Seems like Sax,Trumpet and Solo Strings are the most inconsistent across the brands. Pianos in general sound OK on all Arrangers but different in subtle ways. Would be nice to own one of each.
