I think the virus is a very good snthesizer for emulating the roland classics like 808 and 909. I lately tried to emulate the standart sounds of these two machines like kickdrum, snares and claps and i must say, that the virus comes very close to the originals, because of its analog boost parameters and very analog sounding filters and noise generator. While designing the sounds i always comparded them to the d16 drumazon and nepheton, which are very good roland 808 and 909 emulations. I use the virus in multi-mode on one midi-channel and layer the single drum-sounds on the keyboard, so that i can play the virus like a drum machine on every key another drum sound. If someone like to hear an example of my roland patches, just write me an email ([email protected]) and i`ll send it to you...
