What synth is this?

Does anyone have any idea what keyboard was used on these beats? All three examples were produced by Mike Mosley & Sam Bostic between 1994-1995

Sounds like they're using samples on a Casio FZ-1 to me. The FZ-1's filter and filter envelope has a distinctive sound that can be heard at the tail of the stringy sounds. Obv could be wrong. And anyway, they could have sampled another synth into it, like... I dunno... a DX7 or a Casio CZ-1.. Tuff to answer really.... it could just be from a sample library.

Thanks man, I just listened to some clips, sounds very similar.
