The Prelude is a rebadged SIEL Orchestra 2 with a new paint/silk-screeming job.

Oh yeah, in addition to my previouse post..... the piano [beep] s on this synth, and wine country productions will NOT fix this synth. because its a SIEL.

this synth is great, the flange is out of this world and the strings are to die for, very 80's B movie. on top of that the organ and horn sections hold their own even without being mixed with the strings. the organ section gets it right (at least pretty good for the money) I usually blend "pipe" and "organ 1" with the EQ set to bleed the lows to get a nice combo organ sound. the LFO can be set to mid speed and mid intensity to produce combo like vibrato and chorus can be added to the mix for a Lesleyish effect. AND (drum roll please) my prelude can play all 4 channels simultaneously! the only down sides are that you cant blend the channels, they only have preset volumes. another hindrance is that the pitch and LFO are on sliders instead of wheels which does not lend its self to modern playing styles. But on the bright side the board is encrusted with trim pots and for those with the know how and a few spare parts these provide perfect circuit bending options.
