Yeah but the thing is, Repro is a SYNTH plugin, that was designed specifically to be a synth not an effects processor. If it happens neat, but if it doesn't, its perfectly normal seeing as you get exactly what the plugin was designed to do and nothing more.
I went the other direction here (not by choice). Always wanted a P5 but will never be able to justify buying one, good old Repro is scratching that itch just great though. Bonus points cause it was cheaper than buying a Behringer Pro 1 too during the NI sale last year!
