It's certainly possible (to have variable-clock sample voices synched as a pair for stereo sample replay), I used to have a Synclavier 9600 and that managed it. It also had two D to A convertors per mono sample voice, one for the left output volume and one for the right. I'm not sure if Akai did the same in the S900/950.

Fairlights also had individual voice channels with their own clock to determine sample replay pitch.

I'd be interested if there are any other samplers from that crossover era that did the same e.g. Simmons SDX, Linn 9000 / MPC 60. Anyone know?
