Before you go off looking for all the other VSTi, take a look here at the gear that fellow members have put out for use in FL SynthMaker;

There is a good deal of interesting and innovative gear here to try out and once you are into Synthmaker mode you might try it yourself or perhaps look for other gear made using the original Synthmaker or SynthMaker CM, most it is interchangeable.
New and old gear you may have overlooked.....
