can anyone help in programming that modulated lead sound. I'm presuming it's the LFO modulating the pitch. sound design is not my forte.

any ideas what synths were used on these old prelude tracks??? - I'm on a limited budget at the moment so it's plug-ins for the time being but would be interested if anybody has any ideas??

would really appreciate any help. cheers
