Hi,
Few more discoveries from Help of <<YEM>>
User voices has 256Mb dedicated memory and is works similar with YEM (Grand Suite)
Just this one have
-Mono, Mono Portamento, Mono legato
-40 Elements for each sound, more than KORG (I think 24).
-Kind of PPF or CPF but max 5 packs
-Style Edit - and open Yamaha styles (or midi file)16 tracks where you can edit, save settings and apply these settings to all elements that you want.
-Arpeggios Edit
-Voices edit works with keyboard sound board(only Genos is allowed to do this).
Adding here Bluetooth Audio & Midi, interface color change, 1100 voices, 3 Assignable Switches, ACC, 3 Vocal Harmony, 3 Vocoder, big screen and more.
I think must be compared at least with SX 700.
At this money, with quality of Yamaha voices, I will take one on Christmas tree, just to have it.
Regards!
