Hi Trevor,
I wonder if some of the new voices in Tyros 2 are using up more polyphony than similar voices in the Tyros1.

If the new voices are layered, and the old ones weren't, then you'd be chewing up more polyphony, therefore you may be getting dropouts?

Unfortunately I don't own a Tyros, but the manual may tell you if the voices are layered? and how much polyphony certain voices use up.

best wishes
Rikki

Some styles are faltering slightly and as T2 is supposed to have the same 128 note polyphony as T1 I am a bit puzzled.
