Sounds EXACTLY like an SD2. I
DID own one for a while. Sold it because I thought it sounded pretty ordinary really, for the money I paid. Good decent sounds yes, but nothing to make anyone go "wow".
To try and compare a SD2 to the Tyros 4, is well, silly!!
There is none. SD2 is a bread and butter GM module, sounds are dated and only sound
acceptable when in ensemble playing, as is the case with the demos.
