I have dealt with Spectrasonics over years with there fine Drum software RMX now they have come up with an amazing Bass module of sounds, the Chapman stick and fretless blew me away, go to this link and in the column 2nd one down they display, select electric demo's this is way worth listening tohttp://tinyurl.com/yfdknry  the attack and control of the sound is purely amazing, crank it up

Nice VSTi but I still prefer the real deal

yeah me too!

It's quite amazing what they are able to do with good sampling and programming nowadays.
