ACHTUNG, ich habe meinen englischen text kopiert, falls es nicht erwünscht ist (war zu faul ins deutsche zu übersetzen , übersetze ich es nachher wenn ich wieder zurck bin . okay im heavily into Roland synths atm cause so many old school new age, soundtrack and game musicians used their synths and i already heard so many sounds used in the tracks! these are the 3 modules so far which seem ALL synths? (NO ROMplers!) and which have not the same presets as the other one or are follow ups from any modules i listed and are the latest in their series'? please correct me if im wrong somewhere . Roland D-550: Module version of D-50? with more options, sounds etc.? full synthesizer? is it the latest of its kind or were there any follow up models which had all features + sounds of it maybe? Roland JD-990: Module version of JD-800? same questions Roland XV-5080: Module version of JV-80, JV-1080, JV-2080, XV-3080? same questions As for EVERY unit i listed i didnt find any VST's, i found some kontakt libraries which seem to be illegal and also they wouldnt replace the units as they only have presets and you cannot synthesize your own sounds.
